The Loop Antenna has the advantage of being less affected by reflection signals due to its Faraday shield. By itself, the Loop can provide the entire Antenna requirement for direction finding provided the signal is strong to be received by the untuned Loop. If the signal is too weak, Yagi is recommended for its directional gain. If the signal is to strong, the use of an attenuator may be required. Radio direction Finding is partly art, partly a science. It requires skill. You may need to practice to acquire that skill. Happy Hunting Actual size of the Loop Antenna BNC Connector Usable from 1Mhz to 800Mhz Max Signal Max Signal Null line 1

2 2 RDF1 Get the direction Batos Radio Direction Finding Antenna RDF1 can provide a very sharp bearing, readable to plus minus 5degrees and has the advantiage of beeng less affected by reflection signals due to its Faraday shield and construction.so the antenna can be used for selective signal reception & in turn antenna can be used for direction finding. Radio Direction Finding is part scince part art. It requires knowledge and skill. RDF1 Loop Directional Antenna Get the direction

3 3 Electronic Variable Attenuator 0-100dB Fixed Attenuator 25 & 50dB

4 4 Wi-Fi B1 Wireless Lan Antenna 11 Mbit/s(802.11a,b,g,n) Antenna 6dB gain used for Wi-Fi (Wireles Lan) 800 & 2400Mhz. omnidirectional with BNC male plug. Wi-Fi B1 270mm by 16mm

5 5 Field Strenght meter with sensitivity Adjustment RF Sniffer Rf Sniffer is a Simple (no batteries required) Field Strength Meter yet also quite sensitive. It has sensitivity adjustment.

6 6 Antenna Inductive Coupler 3 Simply place the Coupler over the Antenna (Rubber Duck) and join the plug to your home Base Antenna.Now you can Receive or Transmit without removing your portable antenna and get the benefits of the home base Antenna. For CPF applications (2 way radios)in order to stay legal you will require Inductive Coupler to use your handheld radio on a Car or Home Base Antenna. No Mess no Fuss! Plug and Play!
