BROAD BAND ANTENNA
The Comet CHA-250B is a newly design broadband vertcal requiring no ground radials.
this antenna is extremely easy to assemble, requires no tuning or adjustmnets and VSWR is under 1.6:1 continuosly from 3.5MHz-57MHz
it is not a 1/4 wave vertical, but an end-fed long wire type antenna with a matching transformer in a vertical position.
Broadband:
TX: 3.5-57MHz

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. A 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. A In mountainous areas the pattern will not reach valley floors or mountain tops. A 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.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.

MEDIUM DUTY LIP MOUNT
Medium duty lip mount, 3 adjustment planes.
Attach to any lip on the vehicle, vertical or horizontal, as long as the lip is no more than 1/4″ thick. The mount will adjust to vertical.
The RS-720 has a 5/8″ hole to accept an SO-239 (PO) type connector like the standard mobile cable assemblies: 3D4M, 3D5M, CK-3M, CK-3M5
The RS-730 is a similar lip mount however the footprint is larger. If you have limited space along the lip edge, the RS-720 or RS-720NMO is a better option.
Footprint: 2.1″ x 1.15″
SKU: RS-720-28
