According to Editors and Engineers Handbook, the inverted L is a form of
Marconi antenna. It further says that it is usually 1/4 wavelength long which
is approximately 137 to 138 feet long for 160 meters.
Does an inverted L antenna have to be resonant?
What would be the result if you had room to make the inverted L 5/8 wavelength
long? Would that make the feed point impedance higher and easier to feed. Also
would the antenna have better radiating characteristics? Maybe give it a little
gain? I have the room to extend an inverted L in that manner.
I am in an antenna project re-erecting towers, and loops as well an HF quad. I
am still in the planning stage for the lower frequency HF antennas. If you have
experience with longer inverted L antennas or have experimented with them, I
would appreciate knowing the benefit of your hands on experience. Thanks and
