Spider Beam Hf Antenna

Spiderbeam high performance lightweight antennas.

Spider beam hf antenna. The driven element is a directly fed multiband dipole again contributing to a simple broadband and low loss construction. Further development yielded a complete 5 band beam 20 17 15 12 10m a warc. It is constructed of 3 interlaced wire yagi antennas strung on a common fiber glass spider. Spiderbeam yagis feature full size elements with individual driven elements for each hf band fed from single feedline for monobander level performance.

The spider beam is a trapless multiband yagi constructed of 3 interlaced monobanders making it a highly efficient antenna and simple construction. The whole antenna weight is only 5 5kg 11 lbs making it ideally suited for portable use. Www spiderbeam us is the exclusive distributor and online shop for usa canada.
