Thank you for purchasing the SE HF X-80 VERTICAL, this instruction sheet should help you get the
best from your new antenna.
The SE HF X-80 consists of a 6 m aluminium vertical radiating section and an UNUN transformer
used to lower the high impedances found at the feedpoint of the vertical to the 50 Ohms that is
required by your transceiver.
-Type End fed vertical antenna
-Frequency TX/ 3.5 – 52MHz (with ATU)
RX/ 1.8 – 55MHz (with ATU)
-Max power 400 Watts PEP
-Impedance 50 Ohms
-Connector SO-239
-Height 6 m
Assembly and mounting:
Before you install your antenna, select the most available open site away from power lines and
telephone lines. The antenna can be mounted at ground level or at height so giving you many options
for installation.
Mount the antenna using the u bolt or other attachment.
Assemble aluminium elements using jubilee clamps, leaving 11cm in each section and secure.
At the top of the base cradle place the three nuts and bolts into the black moulding and secure.
Attach the PL-259 plug on the 50 Ohm feeder coax to SO-239 socket on the UNUN.
We recommend that you should always earth at the tuner point rather than at the transformer for best
performance and safety. If you wish to ground the antenna, attach adequate wire to the base cradle.
For permanent installation it would be prudent to seal the jubilee clamps with amalgamating tape or
similar to prolong the life and quality of the antenna.
