Another month on, and my home brew 23cm yagi has not progressed very far. In my defence, I was distracted by the gift of an old J Beam 15 over 15 (or 16 over 16, depending on which bits you count!).
This I have cleaned up, and tested in last night’s 23cm UKAC from Long Mynd G/WB-005.
It isn’t at first glance the most practical antenna for SOTA, but it is very light, 900mm long, and hangs easily on the back of my rucksack.
Results compared to last month, using the PCB patch antenna, were better with 36 versus 34 QSOs, 9 Locator squares versus 8 and ODX of 240Km versus 198Km. Not a statistically significant comparison of course, because conditions might have been different, and different stations will have been active.
In the context of SOTA (rather than a contest) perhaps not enough of a difference to make it worth the extra weight and mounting requirements?
“Pointy” antennas do have pros and cons. I heard two strong stations in QSO. They had been working (calling CQ) on the same frequency as each other, but it was only after an hour and around 20 QSOs each that they became aware of that, presumably when their beam headings coincided! Having laughed about it, one of them agreed to move up 5KHz.
My ODX contact was with the same station as last time - though he was in a different location. I heard him for the first time late in the contest, and we had an easy exchange both ways, as compared to a bit of a struggle both ways last month.
Here is a photo of my set up, the transverter being mounted above the antenna. Happily the forecast heavy rain and lightning didn’t materialise:
It was good to be chased by Matt G8XYJ, and have a S2S with Frank G3RMD on Cleeve Hill G/CE-001
