Spiderbeam 20-15-10m HD

The Heavy Duty Spiderbeam is a specially reinforced version, optimized for permanent installation at home. Doubling the wall thickness of the aluminium and fiberglass parts added a lot of extra ruggedness to the design, making it strong enough to permanently survive severe weather conditions. for many years. All parts are made from high quality materials resistant to weather, UV rays and corrosion.

The well proven electrical concept remains unchanged: 3 monobanders are interlaced on one boom, forming a highly efficient 3-band yagi. At 10.7kg this full size beam is still a lightweight, compared to many other permanent yagis in the same performance class.

Putting together this antenna kit will be a fun and educational project. It contains all the necessary parts to make a 100% complete antenna, as described in the construction guide. Nothing beats the satisfaction of cracking pile-ups with an antenna you built with your own hands
