SITUATION The DIRECTV () polarity SlimLine dish with SL5 LNB to receiver distance exceeds 100 feet. (Reference SlimLine installation manual) SOLUTION Model -T powers a DIRECTV SlimLine dish with strong levels and polarity locks the four dish outputs relieving the receivers from powering the LNB. RELATED CONSIDERATIONS Splitting the -T output to two switches requires DBS splitters with passing to only one port or diode steered splitters. Models HFS-, HRvSP or HFS-D may be used. Color coded jumpers are suggested to be sure the polarities are maintained through the splitters to the switches. FEATURES DBS Compatibility.......

(500 ma total) 18 V = 00 ma, 18V khz = 00 ma, = 50 ma, khz = 50 ma. The 18 volts originating at the must arrive at the SL5 above 16 volts for the SL5 to operate correctly. Up to () volts can be lost in the coax. Current x Resistance = Voltage loss Solid copper RG-6 has a typical loop resistance of ohms per 100 feet. At 50 feet the resistance is 10 ohms. 0. Amp x 10 ohms = volts loss DIRECTV recommends that the distance between receiver and dish be less than 150 feet of solid copper RG-6. LA1A LA1A 16 V minimum 00 feet RG-6 0 V -T Model -T starts with 0 Volts to provided extended dish to home distances. The extra volts buys an extra 00 feet RG-6 distance. The extra coax distance increases the signal loss which model LA1R offsets. Amplifiers near the dish increase the current draw from the Polarity locker and increase the voltage loss to the dish. Model LA1R draws 50 ma per polarity. The LA1R at the polarity locker does not affect the current loss in the cable to the dish. At 00 feet the resistance is 16 ohms. 0.5 Amp x 16 ohms = volts loss 0 V - V = 16 volts to the SL5 Revised Aug 1 01
5 to SL5 Communication Multiple s talking to the SL5 creates strange field problems that can be attributed to khz phasing. Multiple apartments could potentially power switches, an amplifier and the LNBs. However, splitting the inputs with passive splitters combines the outputs of the switches. Multiple khz signals when combined can create constructive and destructive interference. 180º out of phase combining will reduce the khz signal to zero! Model -T polarity locker located between the splitters and LA1A amplifier blocks the khz signals generated by multiple switches and generates a fresh set of voltages and khz tones. 16 V Min 10 1 17v LA1a 1 18 Legacy Legacy 99º/º 18V 18V k Legacy Legacy 99º/º 18V 18V k Legacy Legacy 99º/º 18V 18V k SWM k Port SWM 10º/110º /119º k Port SWM k Port HRvS HRvS HRvS HRvS 0.
