KY6R Mag Loop Gamma Match

4 Foot Mag Loop With Gamma Match (Before Trimming)

From Gamma Match

Thanks to comments from Bas,  and John, I will try another feed loop – and because I have experience with building gamma matches for my home brewed HF yagi’s- which worked very well, I will switch to a gamma match – or “psuedo gamma match” as John suggested.


I’ve also ordered a NOS vacuum variable that has less range – and I expect better tuning than the one I have. This one is 5 – 100 pf instead of the one I have – which is 7 – 1000 pf. I need something that isn’t so ridiculously sharp to tune. The antenna as is is a very narrow bandwidth antenna – so while I love the gear and the stops on the cap I have now – I’ve learned it probably wasn’t the greatest choice. I should be able to sell it pretty easily – and I got a really good price when I bought it – so I should be able to recoup that cost.


I found this as well – actual size calculations
