A 70 microhenry, or any inductor, is lossy. Why not make the RV part of
a small loop which can be tuned with a low-loss capacitor?

My father-in-law was W1DBM, now SK (born 6-6-6) who did the RV thing and
ham radio most of his life. He found his Airstream loop was 15 to 32 dB
better than a trailer dipole or whip.

W1DBM`s loop appears in a 1978 ARRL "Antenna Anthology"
