Productomschrijving

The Sigma Euro-Comm HF360 XP is an end fed vertical antenna, capable of allowing the user to work 80 meters through to 10 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 1KW* pep. The antenna comes with fixings and installation guide.

How it works: The antenna is fed using 50 Ohm coax via a SO-239 socket at the base of the unit a 4:1 UNUN transformer is located in an IP65 weather sealed box at the bottom of the bracket section of the fibre glass elements. The antenna comes in four parts, three fibreglass 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.
