Comet GP-9 Antenna
Dual-Band 146/446MHz Base or Repeater Antenna

Please note: Due to the size of this antenna, additional shipping charges will apply.

The GP-9 is the highest gain, dual-band 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 will 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.
