[TowerTalk] What do do on 80 when height restricted?

[Mike & Becca Krzystyniak]

Hi John,

   Back in the 70's, on a city lot in W9 land, I used a 40M vertical and
added a make shift ~12' diameter top hat.
   Maybe more like an umbrella hat but it did it's thing.
   All you needed at the base to tune it was a tapped inductor (making an
L-match).
   Adding a relay to select the tap points I recall ~75khz BW on 3.525 MHz
for CW, and switching the match achieved something similar at ~3800 KHz.
 
For comparison, I also had a low dipole at 35' on 75m.  
For DX the vertical won out most of the time by around an S unit.

YMMV

PS: I have a 5BTV at the Montana cabin. 
    It hears okay but Xmit on 80M always seems futile.

My son KC2PWX is looking for a solution to a 80 meter antenna, problem is he
has about 30-35 vertical feet he can go. He is using a ground mounted 5btv
but is is awful on 80. Any idea?
