SE HF X-80 XP - 1kW HF Vertical Antenna 80 to 6 Metres with Heavy Duty Aluminium

(Please note the aluminium tubes used for the X-80 XP are 1.2mm or 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 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 1KW* 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 4:1 UNUN transformer is located in an IP65 weather sealed box at the bottom of the 6-meter telescopic aluminium element. 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. The antenna can be grounded if the user experiences excessive local static noise, but as the UNUN is DC grounded: grounded will not affect the tuning ratios.

Band with External ATU:

• 3.5 MHz 80m 1:1
• 5 MHz 60m 1:1
• 7 MHz 40m 1:1
• 10 MHz 30 m 1:1
• 14 MHz 20 m 1:1
• 18 MHz 17m 1:1
• 21 MHz 15 m 1:1
• 24 MHz 12m 1:1
• 28 MHz 10m 1:1
• 29 MHz 10m FM 1:1
• 50 MHz 6 m 1:1

Technical Specifications:

• Type: End fed vertical
• Frequency: TX / 3.5 - 30 MHz, RX / 1.8 - 55 MHz
• Power Handling: 1 kW PEP or CW & 200 watts max for data modes
• Impedance: 50 Ohms
• Connector: SO-239
• Length: 6 meters (19.7ft)

Please use a good quality 50 Ohm coax, RG-213 or Mini 8 are probably the best choice.

*1kWpower 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 you are using a high-power amplifier, it is essential that an external ATU is used between the antenna and the amplifier, otherwise damage may occur.
