[Heathkit] HN-31 Cantenna

Dick,
The mounting method and probably the oil to some degree, causes the load to
be reactive as you go up in frequency.
It never was designed for anything more than a basic load.
There was a article in the ARRL Handbooks explaining the problem; dont know
if its still there.
