...under perpetual construction.
My vertical antenna; actually it is a L antenna, with a vertical section of 16 m and a horizontal part comprising two wires departing from the top and ending on my house roof, with a spacing of 1 m and a length of 23 m (the wires are barely visible in the picture). It has been used on 137 kHz, 1.8 MHz and 3.6 MHz. And, yes, I'm the one at the base of the antenna.
To tune the antenna on 137 kHz I now use a homemade variometer. Its inductance can be varied from nearly 3.9 mH to 1.3 mH; this wide range is useful in /P operation, where one don't know in advance the aerial characteristics. Anyway, my fixed vertical at home need "just" 3.3 mH to reach the resonance. To get an idea of the coils size here is a picture of me holding the variometer at the base of the antenna.
The two coils were designed using the tools described in my variometer design page
I'm also active on the 1296 and 5760 MHz microwave bands, but unfortunately the time available for this activity has decreased much lately. Anyway my brother Nicola, IN3LBQ, which shares with me the interest in ham radio, keeps proposing new mountaintops here in north Italy for the contest weekends; here is a picture of him on the Hühnerspiel (Amthorspitze) (2750 m a.s.l.), near the Austrian border, one of the many mountains visited during our endless search for a better /P location.
In this photo you can see some of the equipment I use for the 6 cm; the 5760/144 MHz transverter is mounted directly behind the 60 cm dish corrugated feed. A small 3 elements Yagi is used to monitor the 2 m band during the contest.
