My activation of Long Mynd G/WB-005 on 160m last night (4/11/20) was more successful than I expected - and I may not have got around to trying it but for the challenge.
A 1.8MHz dipole is big, and quite a lot of tension is required to keep the wire from sagging. I was a bit over enthusiastic during setup, and split a section of my telescopic pole. Happily it was the bottom section, so the rest of the pole was useable. This put the centre of the dipole at about 6m.
I initially rigged the antenna along a wire fence, as I have often done before, but the sag in such a long antenna brought it too close to the fence, and I couldn’t get a match with the Elecraft T1 tuner. So, I moved the ends 3m or so away from the fence, using my walking poles to keep the ends clear of the ground. The match was still less than ideal, but not bad enough to upset the FT817.
I fired up on CW and the first three stations were soon in the log. As I changed to SSB, I noticed that I was still running the 2.5W used for antenna tuning, and from then on I used 5W.
I wasn’t sure what to expect, but I hoped for at least one contact. Four to qualify the summit would have been even better, but to get get ten callsigns in the log was very pleasing!
From this statistically insignificant sample of 1 activation, there does seem to be a sweet spot around sunset. Playing with the antenna from 15:50, activity seemed to be growing. In the minutes after sunset, I was bounced of my chosen frequency by a strong station, and took a little while to find a clear one. (The station did repeatedly ask if the frequency was in use before CQing, but he clearly couldn’t hear my puny signal). Then, by the time I pulled the plug at around 17:45, activity seemed to have dropped off. (Was that condx, or just meal time…?)
Thats a lot of wire to coil up!
I can see there is a case for using a shorter, loaded, antenna and a bit more power to compensate - but I might try this again. Must get some kite winders…
Many thanks to all who chased me, and all who listened out just in case.
