Product Description

The GMRS J-Pole  is tuned for maximum performance on the 462 – 467 MHz General Mobile Radio Service and UHF public safety band. GMRS radios are gaining in popularity daily; inexpensive and effective, these radios are redefining how families keep in touch. Installing a good external antenna will give you the fange you need to keep everyone in touch.

This antenna has an SO-239 connector on it which mates to a PL-259 connector. These are the standard style UHF connectors. Please contact me if you radio system uses a different style connector, as you may require an adapter. If your base radio can accept an external antenna (many of the better models can), then adding one of these antennas will greatly improve your range. This antenna will also work on any of the commercial land-mobile and public safety frequencies located between 462 and 467 MHz.


  • GMRS Simplex and repeater operations, extend the range of your GMRS radio
  • Low noise floor easily captures weak signal stations
  • Omnidirectional radiation pattern works great with handheld and mobile radios
  • Works with UHF Public Safety, Business, and Land-Mobile radio bands
Not all GMRS radios can take an external antenna. If you have questions about this antenna or don’t know if your radio is compatible with it, please contact me first with the model of your radio. I’ll try my best to help you out.

    How is the UHF GMRS antenna 19″ long when a 1/2 wave at that freq is around 12″?? This is assuming 30″ total subtracting 11″ base equaling 19″ radiator. This is not adding up to me…

    The J-Pole antenna is a half wave radiator with a quarter wave matching section. The overall length of the GMRS J-Pole is 30 inches, so if you take the length of the 1/2 wave radiator, plus the length of the 1/4 wave matching section, and the length of the mounting section below, it all adds up to to about 30 inches.
