Constructed of high-quality reinforced fiberglass and finished to match Digital Antenna’s award-winning antennas, our antenna extenders are used to increase the height of an antenna to improve effective range or to place an antenna above on-board obstructions that may interfere with proper radiation.

All extenders mount standard 1"–14 threaded mounts. Use a DM268 center brace when the combined length of your antenna and all extensions is more than 8'.  Straight and tapered extenders available.
