1 Scope

After using a GAP TITAN for over 10 years, I found that it was more and more out of resonnance, due to oxidation and moss growth. So I had to buy another shortwave vertical.

The small 1" pole was too lightweight, so we had to remove the fundaments and install a new massive tube as a mounting base for a new mast.

My friend Bernd DJ6PA advised that I should try another vertical which he had good experiences of, this time a HY GAIN AV-6x0, and since I have little space, I decided to buy the type with most shortwave bands.

WIMO sent it to me in no time, as usual: https://www.wimo.com/hygain-hf-vertikal-kw_d.html

And WIMO also has the original documentation for download.

Note the spokes in the upper section of the antenna. There are two extra spokes in the package, you have to trim them in order to adjust the resonnance. Tuning is done by modifying the capacity.
