Overview

Bushcomm Three-Band End-Fed Antennas

Bushcomm Three-Band End-Fed Antennas are designed and manufactured in Australia and are intended to offer simple and very efficient operation on the 40, 20 and 10 meter bands.

Constructed for emergency, temporary or permanent installation in some of the world's most inhospitable environments, they are built using only the highest-quality materials. At only 12 meters in length, they will easily fit into most installation scenarios.

Commercial antennas are rated with a usable VSWR of 2:1 or under. Rating the Horizon End-Fed using this method the resonant band width is appropriately 100 kHz at 40 meters, 300 kHz at 20 meters and 400 kHz on the 10 meter band. In most cases this will be fine. But if you prefer wider band width or tighter SWR an on-board tuner or the addition of a good-quality external tuner will help.

These antennas use the grey balun box as their feed point and termination point for one end of the antenna. This end can be a tower, pole, side of the house, tree etc. Simply stretch the main radiating element outwards and pull it tight with your support rope. As the wire is G304 stainless steel, it may be pulled quite tight and will not stretch. This antenna is ground independent so grounding or radials are not required.

When manufactured the antennas are hand tuned at approximately 3m (10 feet) above ground. For this reason when you install the antenna the height above ground or proximity of trees buildings sheds and so on will affect VSWR. You may have to retune for your requirements.
