ANTENNA CONNECTION

The type of the antenna system, consisting of the antenna, ground, and feed line, will greatly affect the successful performance of the transceiver. Use a properly adjusted 50 antenna of good quality to let your transceiver perform at its best. Use a good-quality 50 coaxial cable and a first-quality connector for the connection. Match the impedance of the coaxial cable and antenna so that the SWR is 1.5:1 or less. All connections must be clean and tight.

While the transceiverÕs protection circuit will activate if the SWR is greater than 2.5:1, do not rely on protection to compensate for a poorly functioning antenna system. High SWR will cause the transmit output to drop, and may lead to radio frequency interference to consumer products such as stereo receivers and televisions. You may even interfere with your own transceiver. Reports that your signal is garbled or distorted, especially at peak modulation, may indicate that your antenna system is not efficiently radiating the transceiverÕs power. If you feel a tingle from the transceiverÕs cabinet or the microphoneÕs metal fittings when you modulate, you can be certain that, at the least, your coax connector is loose at the rear of the radio and, at the worst, your antenna system is not efficiently radiating power.

Connect your antenna feed line to ANT 1. If you are using two antennas, connect the second antenna to ANT 2. The EXT RX ANT jack can be used to connect a separate receiver. Note that this jack must be enabled by Menu configuration {pages 24, 27} before it can be used.

CAUTION:

Transmitting without first connecting an antenna or other matched load may damage the transceiver. Always connect the antenna to the transceiver before transmitting.

Use a lightning arrestor to prevent fire, electric shock, or damage to the transceiver.
