Uhf bi-directional antenna
The ALP-600 will receive any frequency from 520 MHz to 760 MHz. The "gain" of this antenna enables it to receive signals from a greater distance than a typical "whip" type antenna. Log periodic antennas are also directional and will have the best reception when pointed at the transmitter. This yields the benefit of less interference from unwanted signals coming from the back or side of the antenna.
