[TowerTalk] Hustler mobile resonators dipole

[Pete Smith]

Pretty funny -- I wasn't sure what Tom meant by a "Marconi", so I went to 
the ARRL Antenna Book to look it up, and the only reference in the index 
was to the guy who did those early experiments -- *that* Marconi.  ON4UN's 
book had no index reference to Marconi at all.

 From context, I infer that Tom is talking about base-feeding one mobile 
whip, as originally intended, and placing it over a good ground 
plane.  Correct?  In that case, wouldn't another, more efficient mobile 
antenna be a better choice?  I used a Hustler mobile whip in a garden 
apartment back in the 70's, and while it worked, I never had really good 
feelings about the resonator, since it got warm with only 100 watts CW.
