2G 3G GSM Built-in Antenna Spring Coil Helical Antenna for TV Remote Controller

 

A CB antenna spring is a metal 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.
