SIGMA U.K. - HF - X-80 XP - VERTICAL ANTENNA - 80 TO 6 METERS (3.5-54 MHz) - MAX. POWER: 1 kW p.e.p. - LENGHT: 6 m

- HEAVY-DUTY VERSION WITH 1.2 mm (18 GAUGE) THICK ALUMINUM TUBING -

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 comes complete with all fixings and fixtures and full installation guide.

The antenna can be pole mounted at ground level or elevated depending on the user personnel requirements.
 
The UNUN is BIGGER than the smaller sister X-80, and can withstand power up to 1 kW p.e.p. at the best tuned point.
This antenna is recommended for anyone operating in FT8 or other continuous carrier modes with powers above 80 W.

How it works:
The antenna is fed using coax via an SO239 socket at the base of the unit a UN-UN 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. 

TO FURTHER IMPROVE THE EFFICIENCY ON THE 40 & 80 METERS BANDS YOU CAN PURCHASE THE
"PLUS KIT" OPTIONAL RADIAL KIT (see at the bottom of this page)

The antenna can be grounded if the user experiences excessive local static noise, but as the UN-UN is DC grounded, grounding will not effect the tuning ratio's.
