Whip Antennas

Because the transmitter tunes across such a broad
frequency range, it is best to use the appropriate antenna
for maximum operation. Two antennas are included with
the transmitter, and are shipped from the factory pre-cut
and fully assembled. Each antenna covers three blocks.
Use the chart below to determine which antenna best fits
your needs.

Looking into the 3 pin LEMO mic connector from the out-
side of the transmitter, the pin centered in the two guide
slots is pin 1 (ground). Pin 2 is a 1k resistor to ground.
Pin 3 is the audio/bias connection for two-wire micro-
phones and line inputs.
