Comet GP-9M Dual-Band 2m/70cm Base Antenna, 16 ft 9 in, SO-239

The Comet GP-9M is a high-gain dual-band 2-meter/70-centimeter base antenna with a three-section fiberglass construction. Its omnidirectional pattern concentrates coverage toward the horizon, with 8.5 dBi gain on 2 meters and 11.9 dBi at 440 MHz.

• Bands: 2 meters and 70 centimeters
• Gain on 2 meters: 8.5 dBi; three 5/8-wave elements
• Gain at 440 MHz: 11.9 dBi; eight 5/8-wave elements
• VSWR: 1.5:1 or less
• Maximum power: 200 watts SSB / 100 watts FM
• Connector: SO-239
• Assembled length: 16 ft 9 in
• Antenna weight: 5 lb 11 oz
• Fits mast diameters: 1.25-2.50 in
• Wind survival rating: 92 mph
• Construction: heavy-duty fiberglass, three sections
• Threaded sleeve helps protect the antenna/coax connection

High gain produces a narrow elevation pattern. Comet recommends low-to-mid-elevation installations and does not design this model for extreme mountaintop wind and ice conditions. Observe the separate SSB and FM power limits.
