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.

  • GAIN dBi: 2M: 8.5dBi 5/8 wave x 3, 440MHz: 11.9dBi 5/8 wave x 8
  • Max. Power: 200 watts SSB/100W FM
  • Length: 16′ 9″
  • Connection Type: SO-239 (UHF Female)


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.
