My 66ft EFHW is resonant on 40 thro' 10 including 30m (SWR is just above 1.5:1 on 30m) it is strung up with a dogleg around mid length.?
What appeals to me is that it is simply fed at one end and only has a single 2metre counterpoise.
I found it best with the feedpoint elevated above ground (1.5 metres in my case).
I estimate it is a few db down when compared to a dipole and seems to be borne out in real life when observing signal reports on FT8 - it is a compromise antenna after all.
All in all, it's decent performer with minimal visual impact (essential according to SWMBO (She Who Must Be Obeyed)) !
I plan to extend it to 80m with a loading coil as per some of the linked designs in the above posts.?
