    Comet GP-9

    Comet GP-9
    Price: $167.95
    
    Manufactured by: Comet Antenna

    The GP-9 is the highest gain, dualband fixed station antenna available from COMET. If you desire the absolute maximum coverage area, this is the antenna to choose. The radiation pattern is directed to the horizon omni-directionally around the antenna. However, keep in mind that a high-gain antenna pattern has narrow elevation angle.

    In mountainous areas the pattern may not reach valley floors or mountain tops. If you need to cover areas around the antenna that are a few thousand feet above or below the antenna elevation, the GP-6 may be a better choice due to the wider radiation angle of a lower gain antenna.

    A short threaded sleave screws onto the bottom of the antenna providing the antenna/coax connection protection from the elements.

    Although hundreds are in use in repeater systems, it was not designed for mountain-top installation where extremely high winds, ice and other extreme conditions exist. It performs best in low to mid elevation installations where the high gain radiation pattern is most effective.

    I've made many purchases thru The Antenna Farm web site over the years and these guys always get it right! Been using the GP9 for years, it's my go-to antenna for setting up any new stations. I finally talked my neighbors into getting their license so ordered three more of the GP9 and a couple spools of coax to help them get started. Prices have really gone up since my last order of coax but The Antenna Farm is always very competitive in price. Their flat-rate shipping costs less than the gas to drive to my local HRO 100 miles away. Thanks for another great purchasing experience and for taking care of all us radio nuts!!
