2019-06-13 Visiting the Trintelhaven location again for amateur radio 4 months ago
After my earlier stories about amateur radio at the Trintelhaven location Kees PA5Z wanted to go there too to test a dipole antenna for 80 meters that wasn't going to fit in his garden. I felt like taking the fibermast again and the linked dipole on 40 meters, an endfed antenna and enough rope to be able to hang it in some tree. So we loaded radios and antenna material in a car and drove over there. Weather was nice, not too hot. We were hoping to get on one of the grassy fields of the site, but most of the site was taken up by the trucks and equipment for the work going on.So we settled for the far end of the parking lot, away from the restaurant Checkpoint Charlie. We saw that Checkpoint Charlie had a big antenna themselves, most likely an antenna for the 11 meter (27 MHz) band.

It all worked fine on the 80 meter band. The dipole antenna became a bit detuned when there was a big truck parked right next to it. We were at the edge of the parking lot so it could happen.
The 80 meter dipole set up by PA5Z, picture by Kees PA5ZI set up my fibermast and used the rubber strips to lock the elements, because it was windy. I set up the linked dipole for the 40 meter band. There wasn't a lot of room for the guy wires and after a while one came lose making the fiber mast fall over. Some damage: one corner of the balun broke and the antenna wire came lose. But with a simple fix it was up again. Later one element collapsed because one rubber strip wasn't tight enough. I made only five contacts on the 40 meter band. Propagation wasn't cooperating a lot. Kees did not hear a lot on the 80 meter band until later in the day when some Dutch amateurs where in a conversation. Kees was able to report in and get some signal reports.
