SE HF X-80 XP 1kW High Power Vertical Antenna
(Please note the aluminium tubing used for the X-80 XP is 1.2mm 18 gauge wall thickness which is an upgrade from the standard X-80)
The Sigma Euro-Comm Ltd X-80 XP is an end-fed vertical antenna, capable of allowing the user to work 80 meters through to 6 meters by use of an ATU. The antenna can be ground mounted or elevated mounted depending on the users personal requirements. The antenna is rated at 1KW* pep. The antenna comes complete 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 housed in an IP65 sealed box at the bottom of the 6m aluminium telescopic element. The transformer reduces the impedance at the feed point to a more acceptable level, making the antenna much more efficient and allowing for proper and easy tuning via an external ATU. The antenna can be earthed if the user is experiencing excessive local static noise, but as the UNUN is DC earth: earthing will not affect tuning ratios.

Please use good quality 50 Ohm Coax.
*The 1kW power rating is for intermittent amateur radio use (CW or PEP) for data modes (FT-x, RTTY, etc.) or constant carrier data modes, a lower maximum of 200 Watts is recommended.
*If using a high power amplifier it is essential that an external ATU be used between the antenna and the amplifier, otherwise damage may occur.
The antenna can be earthed if the user is experiencing excessive local static noise, but as the UNUN is DC shorted, earthing will not affect tuning.
