Shakespeare 4700-1 12-Inch Stainless Extension Mast

This Shakespeare Style 4700-1 Extension Mast can be used to extend the reach of smaller marine antennas by increasing their height above the water. It also helps them clear obstructions that would otherwise interfere with proper radiation.

Shorter masts like this one are especially useful for mounting marine TV antennas, GPS receivers, and marine satellite TV dishes. A small height boost can make a real difference for those applications.

This version measures 1 foot in length. It's built from stainless steel for corrosion resistance in a saltwater environment. See what else we carry in marine antennas.
