Product Description

Antenna Spring

Introduction of CB Antenna Springs
A CB antenna spring is a compression spring coil that is typically installed between the mount and the antenna itself. Springs are added to antennas to provide stress relief to both the antenna and the antenna mount in wind and in situations when obstacles such as tree limbs are likely to be struck by the antenna. Springs are also sometimes added to an antenna to add length for SWR improvement.

Usage of CB Antenna Springs
A spring is beneficial for most CB antennas, provided you are using a good, conductive spring of the correct size for your antenna. You should definitely add a spring if there is a chance your antenna will strike limbs or other obstacles, or when you need to add length to an antenna for SWR improvement.

CB Antenna Springs options
When adding a CB antenna spring, it is important to use the correct spring, and a spring that is conductive. Any spring specifically sold for CB antennas will be conductive. They often have a wire running through the center of the spring to make sure of this.
The size of the spring is important as well. The weight of the spring should match the length and weight of the antenna. Usually, the spring will fall into one of 4 categories:

Light duty - These are small springs that will usually only support 0.6m or light 0.9m antennas
Medium duty - These are mid-sized springs that will support up to 0.9m antennas
Heavy duty - These are heavier springs that will support up to 1.5m antennas
Barrel springs - These springs have a distinctive bulge in the center. They will support very large antennas like the 2.5m steel whips
You don't want to use a light duty spring on a large antenna. It will sag and do more harm to the antenna and mount than good. Likewise, you shouldn't have a heavy spring on a smaller antenna. The spring will not flex enough to save the antenna if you hit something.
