The 4008 Series Extension Masts are manufactured of the same Shakespeare fiberglass reinforced composites as our fine antennas. Use them to extend the "reach" of your marine antenna by increasing its height above the water.
Constructed of high-quality Shakespeare white fiberglass, and finished to match Galaxy½ antennas. This extension mast can be used to increase height of an antenna and thus improve effective range, or to boost placement of an antenna above on-board obstructions.
Stainless steel upper and lower ferrules with standard 1"-14 thread
Shakespeare Limited Warranty: 5-Years
Mounts not included.
IMPORTANT! If the combined length of your antenna and all extensions is more than 8 feet, you MUST use an upper support bracket.
