This is a quick tour of my Novel EFHW transformer for high frequency bands.
It’s easy to build if you have the right skills, a bit lossy (as they are) and is power limited due to a single core and high frequency,
But it has great SWR, great SWR bandwidth for a half wave, acceptable losses, no ‘controversial capacitor’ and once built it is ridiculously easy and inconspicuous to deploy even on a daily basis whether for 10 m (or 12 /15m) or CB.
And before anyone asks – yes it definitely ‘gets out’ even from a low height in a wooded valley
