Looking for replacement parts for your 3db Gain VHF Racing Antenna? Look no further! Our selection of replacement parts is here to help you maintain and optimize the performance of your antenna. Whether you need a specific whip length for a particular frequency or mounting instructions for optimal range, we have you covered.
The 3db Racing Antenna is the perfect choice when mounted in the center of a flat roof with no obstructions within 18 inches in any direction. If your setup includes a roof rack, light bar, or requires mounting away from the center of the roof, consider the No Ground Plane Antenna for a suitable alternative.
The frequency range of this antenna is 138-174mHz, and you can specify your desired race channel in the notes section during checkout. If not specified, we will tune the antenna to the mid frequency of 151.625mHz. Our convenient cut chart provides whip length recommendations for various frequencies to ensure optimal performance.
Proper mounting is crucial for maximizing the range of your two-way radio. For metal roofs, mounting the antenna in the center without any obstructions within 18 inches in all directions is recommended for the best performance. If you have a roof rack, place the antenna at the highest point for optimal reception and consider using a no ground plane antenna.
When mounting on a car with no roof, selecting a spot in the middle or utilizing the intersection of two tubes as a ground plane can enhance performance. Mounting the antenna to a corner triangle tab and using a no ground plane antenna is another effective option.

Mounting your antenna properly determines the range of your two-way radio. A metal roof with an antenna mounted in the center with no obstructions (roof rack, light bar) 18" in every direction provides the farthest range.
Roof Racks - Mount the antenna at the highest point of the rack. Use a no ground plane antenna.
No Roof - Pick a spot in the middle of the car. The intersection of two tubes can also act as a ground plane. Mounting the antenna to a corner triangle tab and using a no ground plane antenna will work best.
Do not run radio coax and intercom helmet cables in the same wire loom. RF can bleed over when transmitting, putting noise into the system. Never run coax or power cables near MSD or igniton equipment. They create noise and if the coax is too close to the MSD, transmitting can even power the vehicle off!
When tie wrapping the coax to the frame, do not crush the coax. If your coax looks flattened, kinked, frayed, or worn, replace it!
