EWE for 41M?
 
I am looking for EWE dimensions/termination value for an EWE optimized for 41M

Anyone know what they would be???

Thank you!

Too many variables to say for sure.. IE: end fire or broadside, etc...
They are not that critical it seems, but certain lengths show more f/b
than others. For 10 ft tall vertical elements used at 41m, 10-20 ft
horizontal lengths might be fairly good judging from versions for 80
and 160 meters. You might be able to scale those band dimensions for 41m
and get fairly close. The termination resister value is going to depend
on the ground quality, lengths, etc.. But for 41m, I suspect 300-800 ohms
would be in the ballpark. You would have to experiment and find the best
overall f/b ratios.
There is lots of info on the web such as..

Plenty more where those came from..
