MODEL 3110B BICONICAL ANTENNA Introduction INTRODUCTION The ETS-Lindgren EMCO brand Model 3110B Biconical Antenna is specifically designed for radiated emissions testing. This high performance, receive only, antenna operates with in a frequency range of 30 to 300 MHz. The biconical elements are made from aluminum rods and are welded into a fixed assembly. The elements mount onto a balun network which is fabricated of aluminum and the necessary impedance-matching components.
Mounting Instructions MODEL 3110B BICONICAL ANTENNA Step 3. Repeat Steps 1 and 2 with the other washer and biconical element . Now you are ready to mount the antenna on a tripod for testing. Belleville Washer Balun Biconical Element Clamp (Open Position) Output Connector MOUNTING INSTRUCTIONS The mounting clamp of the Model 3110B uses standard 7/8x14 threads and comes with a 1/4x20 thread adapter for versatility when connecting to an ETS tripod or most other tripods for support.
MODEL 3110B BICONICAL ANTENNA Application APPLICATION The Model 3110B is ideally suited for swept site attenuation measurements per ANSI and FCC specifications. Also, the Model 3110B can be used for horizontal as well as vertical site attenuation measurements. A 20 dB pre-amp is recommended in line with the receive antenna to minimize the required transmitted power and to reduce the possibility of saturation of the transmitting antenna.
