5/8 Wave vertical antennas for HF

Our 5/8 vertical for 20m, during a windy day.

Lots of radio amateurs build their own verticals. Most of them tend to stick to vertical antennas with a 1/4 or 1/2 wave sizing. Just a happy few build a 5/8 wave vertical antenna. This is remarkable, since the 5/8 has the lowest angle of radiation and has about 1dB more gain (compared to 1/4 and 1/2 verticals). So the 5/8 should be the favourite choice for DX’ing.

My Altoids L Tuner

A while ago Tjeerd PA3GNZ donated me some Barkleys mint tins (identical to the famous Altoids tins), which are rather popular by QRP builders to house small homebrew stuff. Two weeks later I found a czech webshop, offering a kit called “Altoids L-tuner”. This kit perfectly fits in such a tin. Since this tuner would be a perfect add-on for my 30m QRP transceiver, I immediately ordered it. — more →

Bad luck

Since Adrian PA0RDA was ill during the contest weekend, and we were not able to setup all antennas due to poor condition of the field, we decided to skip the PACC contest. However, on Sunday morning I could not resist to give away some points, so I made a bunch of CW QSO’s on 15m. We hope for more luck in 2014.

Fieldday setup of the revised AV-12AVQ antenna

After more than 40 years of service of my Hy-Gain AV-12AVQ groundplane antenna, of which 25 years on top of an apartment building at about 100 feet, Ernest PA3HCM and I decided that it was time for some refurbishing. The plastic parts were partly broken and others suffered from the heavy conditions the antenna had experienced. — more →
