Extension Mast HD 2'

Shakespeare Classic Extension Masts can be used to extend the reach of smaller marine antennas by increasing their height above the water or by helping them clear obstructions that would otherwise interfere with proper radiation. They are extremely easy to install and mount between antenna base and coupler to raise the antenna above potential interference for increased line-of-sight. They have standard 1"-14 thread with the upper being male and lower female.
