Constructed of high-quality Shakespeare white fiberglass, and finished to match Galaxy® antennas. This 1-1/2" diameter extension mast can be used to increase height of any antenna and thus improve effective range, or to boost placement of an antenna above on-board obstructions.
The Galaxy series features the strongest construction in Shakespeare's product line.
• Stainless steel upper and lower ferrules with standard 1"-14 thread
• Suggested mount: a style 409 or 410, 2-part mounting kit is required for the 8 ft. extension and suggested for the 4 ft. extension. Shorter extensions can use a ratchet mount such as the 4187.
