EFHW Wideband width

Post by **Buick Mackane** » 24 May 2023, 11:50

Recently over hauled my 49:1 EFHW And for some inexplicable reason i have a super wide bandwidth on the higher bands from 25 - 30 Mhz that's 12 - 11 -10m

Approx 1.5 - VSWR All the way through

No idea why, The best my other 49:1 could manage was a 1.8 VSWR on 10m only,

Maybe down to the winding spaces on the unun

Either way i'm not complaining

Check your coax feeding it. could have gone lossy and thats why youre getting low swr readings.
maybe water has gotten into it?

Coax was replaced a few months ago
