SE HF360 Vertical HF Antenna

The SE HF-360 is an end fed vertical fibreglass antenna capable of allowing the user to work 80 meters through 10 meters using an ATU, also not requiring any counterpoise.

The SE HF 360 can be pole mounted at ground level or elevated depending on users requirements. The antenna is rated at 300 watts side band. The antenna comes complete with fixings and full installation guide.

The antenna has 4 sections, 3 high grade fibre glass sections and one stainless steel whip.


SE-HF360 - How it works

The SE HF360 is fed using coax via an SO239 socket at the base of the unit. A UNUN transformer is located in a IP65 weather sealed box at the bottom of the fibre glass element. The transformer reduces the high voltage 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. The antenna was tested without an Atu and with an Atu. Different locations and antenna configurations may alter the results obtained.
