FOR HORIZONTAL ANTENNAS, HEIGHT = MIGHT!

A new antenna concept for combining lightweight wire antennas with lightweight telescoping fiberglass poles, enabling rapid deployment of efficient antennas (within minutes), at heights previously unobtainable with portable products.

Users of the popular Model 404-UL antenna requested an 80m version and Spiderbeam responded with the Aerial-51 Model 807-HD wire antenna. Our 807-HD (heavy duty) uses strong CQ-532 wire for permament installations.

The 807-HD was designed with the same focus on material quality as the other Aerial-51 antennas. It uses insulated, stranded copper-clad steel wire with a breaking strength of 50 kg, and a Teflon-insulated SO-239 coax jack with gold contacts. The Hybrid Balun and RMU are the same as used in the 807-L portable version, but in this heavy duty version the Balun is also potted with Epoxy for better weather protection. This combination of Balun and RMU optimizes resonance of the antenna on all bands, while assuring the antenna and feedline are not plagued with problems caused by common mode current, as most competitive OCFD products are.
