Toroid windings for EFHW

[MM0FMF]

Trapped EFHW match unit

I have a Hamshop.cz Trapped EFHW for 40/30/20m. I acquired it several FN rallies ago (2017?) as I had some Czech Crowns left from a trip and Juerg HB9BIN recommended it. It works, I’ve used in France, Germany, Czech Republic, Poland , Switzerland when doing light-weight activations. (Simple walks, small hills etc. outside the UK) But I don’t know if it works well or not. Yes, I make QSOs but I don’t know if it’s better or worse than a centre fed dipole. I only use it when I don’t want the extra…
