Re: EFHW from ARRL

What’s not discussed is the wide SWR bandwidth measurement relative to the NEC model. Worse is the compensated model that shift the 10m frequency to get low SWR in-band. Bu,t that occurs as a result of added system loss. When I see flattened SWR curves over a wide spectrum, I reach one conclusion.
For me, the unun EFHW would be an antenna of last, or nearly last resort. If it was my only antenna, I would still use it if shipwrecked on an island. But, I would likely turn it into a symmetrical dipole and take my chance of rescue on a single band.
