Spiderbeam 3 HD – 3 Band Beam Antenna Kit 20-15-10 Meters


The Spiderbeam HD 20-15-10 m is a specially reinforced version optimized for permanent installation at your residence.


Doubling the wall thickness of both the aluminium and fiberglass components resulted in an additional degree of robustness to the design, rendering it strong enough to permanently endure extreme weather conditions for many years. All parts are crafted from premier quality materials that can stand up against weather, UV radiation and corrosion.


The 3 monobanders remain in their well-proven electrical concept on one boom, forming a highly efficient 3-band yagi. With a weight of 10.7 kg this antenna is considered lightweight compared to its peers in the same performance class. Assembling this antenna from the kit is an enjoyable and educational experience; it contains all the essential parts, along with an instruction guide for complete construction. The reward of hearing pile-up breaks while using an antenna you built yourself cannot be beaten!
