Ham radio antenna SE HF 360 80 To 6 meters

  • £139.95 GBP

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.

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 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.

The Highlighted bands in the chart below will require a manual ATU, the others an internal ATU.
