This is a 150.8-162 MHz, 1/4 wave, roof mount antenna intended for customers who do not plan to use the GPS capability of the radio. The signals for these antennas radiate vertically, making them ideal for urban environments where buildings can obstruct the signal.
This through-hole mount antenna is compatible with the APX mobile radio series. If the mobile is programmed with multiple RF bands, one mobile antenna is required for each band. Each frequency band has its own RF port.
