The Horizon End Fed Tri-Band Antenna was designed and manufactured in Perth WA. It's a simple and effective option for operation on 10m, 20m and 40m for temporary or permanent use. They are built with the highest quality G304 14 gouge wire with a sturdy grey balun box, designed to withstand the Australian climate. 

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 approximately 100 kHz at 40 meters, 300 kHz at 20 meters and 400 kHz on on the 10 meter band. If you require a wider band width or tighter SWR an on-board tuner or the addition of a good-quality external tuner may be required.  

The Feed/Termination points on one end are enclosed in a sturdy grey box on one end of the antenna which can be attached to a mast, pole, house or tree etc.
