SIGMA EURO-COMM SE-HF-360 FIBRE GLASS VERTICAL ANTENNA 80 TO 6 METRES

Un box and test... Sigma Euro-Comm SE-HF 360 Fiber Glass Vertical antenna The Sigma Euro-Comm Ltd HF360 is an end fed vertical antenna, capable of allowing the user to work 80 meters through to 6 meters using an ATU. The antenna can be pole mounted at ground level or elevated depending on the user’s personal requirements. The antenna is rated at 400W pep. The antenna comes with fixings and installation guide. The power rating is for intermittent amateur (400W CW or 400W SSB) use and not for AM broadcast or constant carrier data modes. For AM broadcast a much higher power BALUN is required." How it works: The antenna is fed using 50 Ohm coax via a SO-239 socket at the base of the unit. A 6:1 UNUN transformer is located in an IP65 weather sealed box at the bottom of the bracket section of the fiber glass elements. The antenna comes in four parts, three fiberglass poles and one stainless steel tapered whip. The transformer reduces the impedance at the feed point to a more acceptable level making the antenna much more efficient and allowing proper and easy tuning via an external ATU and automatic ATU’s found in most modern radios. The antenna can be grounded if the user experiences excessive local static noise, but as the UNUN is DC grounded: grounding will not affect the tuning ratios. The Highlighted bands in the chart below will require a manual ATU, the others an internal ATU.
