80m - 6m

The X80 is an end fed aluminium vertical antenna, capable of allowing the user to work 80 meters through 6 meter bands using an ATU, also not requiring any counterpoise and can be fed using coax cable.

The antenna can be pole mounted at ground level or elevated depending on the user personnel requirements. It is rated at 300 watts pep and comes complete with all fixings and fixtures and full installation guide.
How it works: The antenna is fed using coax via an SO239 socket at the base of the unit a UNUN transformer is located in a weather sealed box at the bottom of the 6 meter telescoping aluminium element. The transformer reduces the high impedances generated to a more acceptable level making the antenna much more efficient and allowing proper and easy tuning via a manual and most automatic ATU’s. The antenna can be grounded if the user experiences excessive local static noise, but as the UNUN is DC grounded, grounding will not effect the tuning ratio’s.
