47 Antenna Phasing & Cupling Cntinental Phaser Design Practices Cntinental phasing systems ffer ptimal impedance and pattern bandwidths with wide adjustment range based n highly accurate, cmputer analysis f antenna twer impedances. All designs avid netwrk cnfiguratins which directly impair bandwidth, such as thse which have excessive individual phase shifts r excess twer base reactance tuning. If special bandwidth cmpensatin netwrks r rejectin filters are used, RF lsses, vltage gradient and circulating currents are carefully calculated and their impact is included in the final system design. All system cmpnents are carefully evaluated and selected n a best- perfrmance/ best- engineering practice basis. Fr example: vacuum capacitrs and vacuum RF cntractrs are used when apprpriate. Cnservatively -rated cmpnents are used thrughut the design. A static drain device is prvided in the antenna cupling unit fr each twer, unless this functin is perfrmed by the grund winding f an existing lighting chke, r ther means. Accuracy f netwrk calculatins is enhanced by the use f digital cmputers. Special system analysis is used t predict r ptimize adjustment interactin, sensitivity and bandwidth. Cntinentals nging antenna systems research assures all custmers that they will benefit frm the mst current prven designs. Intrductin Since its funding in 1946, Cntinental Electrnics has designed and manufactured phasing and cupling manufactured phasing and cupling equipment t meet the needs f bradcasters arund the wrld. Many f the techniques used tday in phaser design were pineered, develped and refined by Cntinental engineers. Cntinental engineering and manufacturing persnnel can draw upn a wide and varied experience in preparing yur phasing equipment prpsal: experience that includes designing, buiding, installing, testing and perating transmitters and related RF equipment ranging in pwer frm 1,000 t 2,000,000 watts. Typical System A directinal antenna phasing and branching system cnsists f: an impedance matching circuit which matches the pwer divider input impedance t the cmmn pint impedance at which the pwer input is measured a branching circuit in which pwer is precisely divided int the amunts f pwer necessary t give the prper rati f fields frm individual antennas phase shifting netwrks in series with each f the transmissin lines ging t the individual antenna twers the transmissin lines the antenna cupling unit (ACU) fr impedance matching between each transmissin line and its assciated antenna twer.

Then, three netwrk mdels f the twers are calculated: ne at carrier, and ne at each sideband. The cmpnents f each netwrk are placed in the phaser tplgy, and the whle system is then analyzed by a cmputer prgram using admittancy matrix algebra. Cmpnent reactances and transmissin line lengths are autmatically adjusted fr frequency. The effects f cil Q and transmissin line lss are included. The frequency- sensitive twer impedance mdel answers tw questins which cannt be answered if the twer system's current ratis r perating impedances are assumed t be cnstant. They are (1) Twer currents at the sidebands. (2) Twer currents at the carrier during the adjustment prcess. btaining the cmmn -pint impedance, VSWR and the twer currents, and the effect each cmpnent has n these parameters, enables Cntinental engineers t prepare an ptimum system design. In additin t "widebanding", this technique can be used t study adjustment sensitivity at carrier. It can als be used t give advance indicatin when a pwer divider cntrl is mre f a phase cntrl and vice -versa Adjustment interactin can be ptimized during the design prcess. Cntinental "Wideband" phaser Cntinental engineers have develped a technique that ptimizes the impedance and pattern bandwidths f a phased array. Fllwing is an verview f this technlgy. After cmpletin f the initial phaser design, the sideband self and mutual impedances are calculated, based n electrmagnetic prpagatin less than the speed f light.

Clr -cded LEDs give status indicatins fr each twer and phaser cabinet. the mmentary push -buttn switches must be depressed fr a full secnd befre switching will begin. This prevents accidental mde change if an peratr accidentally depresses a pushbuttn, and assures that the transmitter has adequate time t remve RF utput. If desired, the full- secnd cntact can be perfrmed autmatically with the additin f tw relays. Remte cntrl capability is built -in t the standard circuit with a "lcal nly" switch fr persnnel safety during maintenance. A separate remte cntrl panel is available as an ptin. Cntrl lines can be specified as 28 vdc r 220 vac. Line vltage t the cntrl panel can be specified as 120 vac r 240 vac; 50 r 60 Hz. A'Failsafé circuit will prevent the transmitter frm returning t the air if a mde change is incmplete. All relays are the same plug -in type. Time delay is accmplished with RC decay netwrks.

G5 Series, Circularly Plarized FM Antennas The G5 antenna was intrduced in Since then, it has becme the mst ppular FM antenna available in the United States. It is an electrically sund, mechanically rugged, thrughly field -prven antenna design. The antenna may be purchased in any number f bays frm 1 t 16 (Series A & B). Each bay level element cnsists f tw segmented series -fed diples that frm a space -phased, circularly plarized radiatr. Each segmented diple is manufactured using a custm -made Wallace Bending machine. The diples are cnstructed f 3-1/8".d. brass which prvides an excellent element bandwidth as well as prtectin against crna discharge failure. The islated feed pint f the tw segmented diples is pressurized t avid the effects f atmspheric changes and metal crrsin n the feed pint impedance. The insulatrs are custm -made melamine insulatrs with machined flange fitting fr blt dwn "" ring sealed flange assembly. Each feed pint is silver sldered t the inner cnductr inside the driven element; the entire inner cnductr assembly f the element is silver plated t minimize antenna lss. Each individual segmented diple can be remved frm any bay level element and replaced with a new segmented diple with n change in the VSWR f the antenna. Each segmented diple is cnstructed with a Page 47 captive male 3-1/8" cax 50 hm inner cnductr cnnectr, and is cnnected t the antenna element using a five blt pinned flange. This unique cnstructin design assures prper diple installatin. Electrically, each element in a G5 array is a 50 hm element at the frequency f peratin. When the array is matched, a quarter wave transfrmatin sectin is designed fr each element's feed stem, s that each element adds in shunt with the ther elements in the array, with impedance f n x 50 hms, where n equals the number f elements being added in shunt. This methd f matching limits the maximum vltage and current in the antenna array interbay cax while utilizing the advantage f a 50 hm bay level impedance. The G5 antenna design is very flexible: it permits side, cmer leg r tp munting n any type f twer. All radiating elements and feed stem are cnstructed f brass; all supprt brackets and hardware are made f stainless steel.

52 G5CPS FM Antenna G5CPS Super Pwer Circularly Plarized FM Antenna The brass radiating element has an utside diameter f 3-1/8 ". The feed pint is cmpletely internal with a pressurized envirnment up t the feed pint. The radiating element is rated at 40 kw, and is limited by the safe average pwer capability f the 3-1/8 rigid cax line. The heavy -wall brass tubing stem can withstand harsh envirnmental cnditins. Deicers are nt recmmended in mderate envirnments because typical VSWR is 1.5:1 r less with 1/2" f radial ice, if the antenna has been field tuned. Heaters fr deicers r radmes are available. All G5CPS antennas use silver -plated inner cnductr cnnectrs thrughut t reduce lsses and heating. Each antenna, supplied with a 6 ft input matching sectin has 50 -hm EIA input. Depending n mdel type, the input is either a 3-1/8 inch 50 hm EIA female input r a 6-1/8 inch 50 hm EIA female input. nce each antenna is cmpletely assembled and factry-tuned t the custmers frequency, it is pressure tested at 10 lbs. pressure fr ne hur t ensure that the antenna is leak -free prir t shipment. The antenna system feed pint is 6 feet belw the bttm bay fr end fed antennas, and apprximately 6 feet belw the center f the antenna fr center fed antenna systems. The hrizntally plarized hrizntal -plane radiatin pattern is mnidirectinal when ple - munted atp a twer; a ± 2 db circularity is typical when munted n a 14 inch diameter steel ple. When side -munted n a twer, the antenna pattern will be affected by the twer structure. Cmplete antenna pattern measurement services are available n a qutatin basis. Hrizntal plane relative field patterns are measured n a full scale mck up f a 20 ft sectin f the custmer's twer, including the ladder, caxial transmissin lines, cnduits, cables and antenna element. Pattern ptimizatin fr bth hrizntal and vertical plarizatin is available fr imprving the pattern circularity f the antenna -supprt twer cmbinatin. Precisin mdel studies are als available fr situatins where larger vertical aperatures f the array need t be analyzed. The G5CPS has a lw standing -wave rati f 1.07:1, r less. ± 200 KHz fr a given channel with field trimming. The VSWR at antenna input withut field trimming is 1.2:1 fr ple munting atp a twer; 1.5:1 r less when side munted n a twer. Multistatin peratin is pssible using a cmmn antenna system due t the excellent bandwidth characteristics f the G5 antenna design. Cntinental can qute filtering cmpnents required fr the diplexing r multiplexing peratin. Statins with a frequency separatin as large as 4 MHz can be diplexed n a cmmn antenna.

59 G4D FM Antenna G4D Dual Plarized Directinal FM Antenna The G4D antenna is designed and built primarily fr the FM statin lcated alng an cean cast r in muntainus areas where there is a need t radiate pwer in a 180 -degree pattern rather than waste energy ver water r int a muntainside. r, where the licensing authrity such as the FCC will allw the use f a directinal antenna t meet sme special requirement. The design f the G4D antenna is based n the elements being ple munted. rmally the antenna is quted with the ple included, but it can als be ffered withut the ple. In that case, exact details f the custmer -supplied ple will be required befre fabricatin begins. The G4D cnsists f vertical and hrizntal elements that are 3-1/8" in diameter and made f brass t resist the effects f weathering. The size f the elements cntributes t the unusually wide bandwidth f this antenna. Typically, the bandwidth is 5 Mhz between the 1.5:1 VSWR pints. And, because f this very wide bandwidth, the G4D des nt require deicing prvisins except under the mst severe cnditins. G4D antennas have been perated with up t 1/2 f an inch f radial ice withut causing serius detuning. Radmes are recmmended in severe envirnments. Because it is a directinal antenna, each G4D is pattern tested n the antenna range prir t shipment. Pattern dcumentatin is prvided with the antenna t meet the filing requirements f the FCC. Because the antenna and the munting ple make up an integral unit, field tuning is seldm required. Typical patterns which can be achieved thrugh the use f a G4D antenna are shwn n the fllwing page. The gain figures shwn are fr the particular pattern achieved and can therefre vary depending upn a statin's requirements. When rdering a G4D antenna, the fllwing infrmatin must be supplied: maximum ERP authrized, true azimuth rientatin, radiated pwer limitatins and their true rientatin, transmissin line efficiency r transmissin line type and length, and the pwer utput f the transmitter with which the antenna will be used. As with all Cntinental Electrnics FM antennas, the G4D is designed t be pressurized with either dry air r nitrgen. A psitive pressure f 3 t 5 punds shuld be maintained after the line and antenna have been initially purged t remve misture.

The gain figures will vary with the pattern shape, and the exact gain figures are determined when the final antenna pattern is achieved. The pwer gain fr the vertical plarizatin cmpnent may be less than the hrizntal plarizatin cmpnent since it will differ a bit in shape. The RMS f the vertically plarized cmpnent cannt exceed the RMS f the hrizntally plarized cmpnent. The vertically plarized cmpnent cannt exceed the hrizntally plarized cmpnent at any azimuth.

61 Antenna System Accessries Ice Warning System The Rsemunt ice warning system cnsists f a cntrller and an ice detectr'. Mst ice warning and heater cntrl systems are perated by a thermstat device; thus, antenna heaters are energized whenever the temperature drps belw apprximately 35 F (1.7 C). Statistically, the prbability f icing seldm exceeds 3 percent, even during the winter mnths. The remaining 97 percent f the time, antenna heater pwer activated by a thermstatic device prvides expensive and unnecessary insurance against icing. The Rsemunt system is designed t reduce antenna de -icing csts and t fully autmate antenna de -icing systems. The Rsemunt system will detect ice and energize antenna heaters nly when ice is physically present, but befre ice accumulatin can reduce antenna perfrmance. The Rsemunt system thus prvides reliable, cmpletely autmated antenna icing prtectin at a fractin f the cst fr cntinuus heater peratin whenever the ambient temperature is belw apprximately 35 F (1.7 C) In many cases, the Rsemunt system will pay fr itself in less than ne icing seasn. Micr -Trak 2580 Antenna Heater Cntrl System The 2580 senses ambient atmspheric cnditins and cntrls pwer t the element heaters in FM, TV, and ther electrically heated antenna arrays. The system prvides aural and visual indicatin f status, mnitrs the cnditin f the heater elements, and prvides an alarm in the event f a failure. The 2580 reduces peratinal csts by cntinually sensing atmspheric cnditins, thus restricting heater turn -n t ice- causing cnditins: freezing temperatures and precipitatin. The 2580 system cnsists f fur basic cmpnents: 2580 Cntrl Unit, TT Temperature Sensing Unit, PD Precipitatin Detectr, and the HF Heater Failure Sense Transfrmer.

These peaks ccur in tw ways: First, the CP -803 eliminates the brief electrical vershts that exist in all audi limiters and stere generatrs-even thse described as versht-cmpensated. Preventing such vershts increases mdulatin with essentially n audible effect n the signal. Secnd, the Prcessr cntrls the high -frequency peaks that are present in all prgram material. Thugh nt acustically significant, these peaks cause ver -mdulatin. Cntrlling them makes greater average mdulatin pssible. The audible effect is minimal, far less than that f cnventinal variable -gain devices. The CP -803 crrects the distrtin that cnventinal prcessrs smetimes create. But there's a basic difference in their peratin: Cnventinal audi prcessrs wrk with the left and right audi. But the Cmpsite Prcessr deals with the stere cmpsite signal that cmes ut f the stere generatr. this baseband signal is made f the left-plus -right main channel, the 19 khz pilt, and the left - minus -right subcarrier.

Mdulatin Sciences Sidekick' SCA Generatr & Audi Prcessr Sidekick cmbines the fur elements needed fr successful SCA peratin int ne package: subcarrier generatr, mdulatin mnitr, audi prcessr and transmitter tuning aid. Engineered t wrk tgether, these cmpnents frm an integrated system which prvides a level f perfrmance previusly unattainable. Crsstalk is dramatically reduced, signal quality is significantly imprved and peratin is greatly simplified. Sidekick is cst effective because there is n need fr redundant pwer supplies, packaging, r input/utput interfacing. Subcarrier Generatr Sidekick has the first crystal cntrlled SCA generatr in the industry. thers use simple free -running scillatrs which are easy t design and FM mdulate, but whse frequency stability is a prblem.the stability f Sidekick is ±0.005% frm 0 t 50 degrees C. Mdulatin Mnitr A built -in mdulatin meter eliminates the need fr an additinal SCA mdulatin mnitr. The peak hlding circuitry lets the meter rise t the maximum deviatin and remain there withut much wiggling. The meter can als be easily calibrated in the field with nly a frequency cunter and a DC vltage surce. Integrated Audi Prcessr Audi prcessing has traditinally been a weak link in SCA transmissin. It is nt uncmmn t find that the audi prcessrs used fr SCA are hand -me -dwn frm the main channel. Unfrtunately, the use f a 75 micrsecnd limiter in a 150 micrsecnd system results in almst n high -frequency peak cntrl. In additin, SCA audi filters which rll ff at 5 khz have the same kind f versht and ringing as the infamus 15 khz filters used in stere generatrs. As in main channel peratin, pr peak cntrl means lw average mdulatin. In SCA, this means increased susceptibility t crsstalk. Transmitter Tuning Aid In many transmitters, prper tuning f the driver and PA stages plays a majr rle in the reductin f crsstalk between the main and SCA channels. The Sidekick has a built -in nise generatr and incidental AM nise meter. ther equipment is needed t nise lad the entire baseband and measure the incidental AM frm an RF sample. The RF tuning can then be "tweaked" t minimize the incidental AM. This ften yields a dramatic reductin in crsstalk.

90 Stere Generatrs Mseley Series 8 Subcarrier Systems Series "8" Subcarrier System frms a revlutinary FM system prviding superir perfrmance. The Series "8" System cnsists f the Mdel SCG -8 Subcarrier Generatr and Mdel SCD -8 Subcarrier Demdulatr. These units may be individually used t meet specific requirements such as SCA service n an FM bradcast transmitter, r telemetry service. This system is ideally suited t aural studi - transmitter link (STL) service. Prviding a means f establishing a secndary prgram channel, the Series "8" System enables multiplexing SCA prgram audi, prvides fr remte pickup link audi, r serves as an interdm n an STL. Cmmand infrmatin frm a remte cntrl system can als be cnveyed by the SCG -8 and SCD -8. The Mdel SCG-8 Subcarrler Generatr is designed specifically t develp a direct FM subcarrier fr multiplexing an FM, TV, r studi -transmitter link transmitter and sund quality are just sme f the characteristics f the perfrmance f the SCG -8. Autmatic carrier muting functins with the absence f prgram audi input. The time delay frm the absence f audi until the carrier is muted can be adjusted frm less than 1 secnd t mre than 5 secnds. A frnt -panel switch enables selectin f this autmatic -mute feature r a cntinuus n r ff subcarrier cnditin. A secnd input applied t a rear -munted BC cnnectr accepts a subaudible telemetry signal. Subaudible telemetry infrmatin frm a Mseley Assciates Remte Cntrl System can be fed directly t the SCG -8. The Mdel SCD -8 Subcarrier Demdulatr was develped as a cmpanin t the SCG -8 Generatr and encmpasses the same design philsphy. Input carrier bandpass filtering enables peratin frm a cmpsite signal surce withut external filters. This filter is a plug -in assembly enabling easy field changes t ther frequencies. The audi utput is sufficient t drive mst bradcast equipment and is adjustable frm the frnt panel. Carrier bandpass and audi lw -pass filters are used in the Series "8" Subcarrier System. Audi perfrmance is tailred t the intended applicatin based upn the carrier frequencies f 26 khz and 39 khz, the nrmal applicatin is either cmmand r telemetry fr a remte system. These applicatins require a 3 khz audi bandwidth. Frequencies f 41 khz and 67 khz nrmally are used fr SCA service requiring 5 khz respnse. As a 67 khz carrier frequency may als be used fr secndary prgram service n a mnaural studi- transmitter link (STL), it can ptinally be supplied fr 10 khz perfrmance. Likewise, 10 khz respnse is prvided when perated at a carrier frequency f 185 khz when using a cmpsite STL fr stere transmissin.
