Switching to vertical: First results

A few months back I switched from a magnetic loop antenna to a vertical one. There were two main reasons to do so. The first one is the ability to be able to remotely tune the antenna. With the I3VHF-loop I wasn’t able to. The second reason was to have¬†support for the 80 (and soon …

Building Inverted-L

I’m busy building an inverted L antenna. Going about 10 meters up and 10 meters horizontal. This gives me the possibility to work on the 80-meter and 160-meter band, using a CG-3000 tuner. I’m currently using about 2x 12 meters of wire as counterpose. This will be a bit more in the near future, but …

Going topbands with new loop

I like my I3VHF loop, like Wimo sells it as Baby loop. It has full coverage between 6,5 and 30 MHz and provides me with the 40, 30, 20, 17, 15, 12 and 10 meter band. I can work around the world in digimode (JT65) with it and there aren’t many day’s I can’t work …

Another new antenna: MFJ-1788 loop

I should stop ordering stuff. Really. The antennes I’ve ordered a month ago aren’t in yet (shame on you¬†vpa-systems.pl) but today I’ve ordered an MFJ-1788 loop-antenna for the 40-15 meters band. Let’s see how this works, in particular on 40-meter, where my day-to-day QRM is always S9 till S9+10, thus quite unworkable. Now wait a …

Testing a new antenna

I’ve bought a Comet H422 rotary dipole to do some tests. This is a trapped V-dipole for 10, 15, 20 and 40 meters. The assembly went fast. It took me half an hour to do so. Now have to find a way to get this thing somewhat more in the sky since it picks up …

Going vertical

I’m currently testing my EndFed antenna vertical, on a 40ft/12m glassfiber spiderpole. I still got the same QRM as before (S9+ on 40m, S6+ on 20m) but the first results look quite good. This is just an expiriment to see if an vertical antenna will fit my needs. I’m in doubt between the Hygain AV-640 …

Sporadic E season started

Around half may the Sporadic E season starts. That brings a few good things for the summer months. The first one is that the 6 and 4 meter bands open. I don’t have a 4 meter transceiver but am able to transmit on the 6 meter band. The only problem for me is that it’s …
