Sigma HF-360
Selected and Distributed by Eco Antenne in collaboration with Sigma-Com
Multiband Efficiency (80m - 6m)
The Sigma Euro-Comm Ltd HF360 is an "End Fed" vertical antenna designed to provide full operation from 80 to 6 meters. Thanks to its versatile design, it can be pole-mounted both at ground level and in an elevated position, perfectly adapting to the needs of any radio station.
The antenna is constructed in four sections: three high-strength fiberglass poles and a stainless steel conical whip. At the base, a 1:6 UNUN transformer enclosed in an IP65 watertight box reduces the impedance of the feed point, facilitating matching via integrated or external ATUs (automatic or manual).
