Whack, whack, whackwhackwhackwhack. Hear that? It’s the sound of low hanging branches, thick brush or the drive-through clearance bar giving your antenna a decent beating. Protect your CB rig with our medium-sized spring, designed specifically for antennas that are up to 3’ tall. This durable, stainless steel spring is rust- and weather-resistant so you don’t have to worry about it lashing around in the elements either. For antennas above 3’, we recommend our heavy-duty spring.

Every antenna should have a spring to protect the antenna, mount and vehicle from hits to the antenna. Firestik springs are made from long-lasting, top-grade electro-polished stainless steel. The upper and lower inserts are made with chrome-plated machined brass and have standard 3/8" x 24 threads to fit all standard 3/8" antennas, mounts and accessories. The medium-duty model works especially well with Firestik's 2' KW & FS series antennas, as well as the 3' FL or RP antennas. Each spring is about 3.0" (76mm) tall with a diameter of 0.800" (20mm).

Medium CB Antenna Spring

Does what it is supposed to do. I will note for others that the 3' Firestik will fold over about 40 degrees with this spring at 60 mph.

antenna spring

spring is to light weight for a 3' antenna should be classified as lite weight spring, when traveling at highway speeds antenna is almost laying flat

Works as it should

Was having trouble with my trunk mount (used it on the lip of my door) constantly slowly tilting back no matter how far I drove. Since I’ve put the spring in I haven’t had the issue once.

Could be firmer

Good quality materials but seems a little too soft for my preference. Bends at least a foot from wind drag at highway speeds with a 3' antenna.
