Then it should be a good basis for comparison, at least on 20 meters.
Even the PAR EF-20/40 may not be comparable on 40 since it's physically only

The definition of Marconi antenna is that it is quarter wave.
A half wave antenna is called a Hertz antenna in some older literature.

In re the comments on Marconi antenna and ground effects, Isn't the Par
end-fed a vertically polrized Hertz antenna, not a Marconi?

Hello,
I have plenty of experience with antennas on mountain tops.
I have tried dipoles on mountain tops with good results. I usually tie
off the center of the dipole at around 15' to 20'. The mountain height
does the rest. I once had a very interesting experience with the issue
of HF and antenn
