Antenna Connectors
The front of the receiver has two SMA connectors, intended to connect to external 50 ohm log-periodic (“Shark-
fin”) or whip antennas. For best performance, keep any transmitters at least 3 feet (1 meter) away from the
antennas. This is because strong radio frequency sources reduce the receiver’s sensitivity. The receiver is
optimized for properly tuned external log-periodic antennas. When whip antennas are used, there is a noticeable
reduction in the receiver’s range. You should periodically check that the connector is still securely tightened.
