My brother Paul, W6PR, uses a five-band 4-element quad at his place on Point 
Loma (San Diego), California. It works quite well on 10, 12, 15, 17 and 20 
meters. He has it on a crank-up tower that is bracketed to the house (and 
therefore a lot of noise is transmitted into the house when the wind blows). 
But he can crank it down to a level where he can work on it on the roof, 
which is somewhat frequently. Salt water corrosion is one of the problems.
The W3LPL contest station has 2 or 3 80-meter 2-element fixed quads. One is 
aimed at Europe and another at South America. Maybe there is another for 
Japan; I don't remember. They are suspended between towers, and he wouldn't 
keep them up if they didn't work.
While I lived in Cedar Rapids, I had a 2-element quad up 40 feet. It worked 
very well, although I wouldn't say it opened and closed the bands. I still 
have most of the parts, but will probably never put it up.

well, if you have the space for one on 15 meters and down, then you =

HUGE the further down spectrum you go. THe loop size for an 80 meter =
quad is 270 feet and just to have the second element as a director will =
mean an antenna that requires nearly a full acre just to be free and =
clear of obstacles. The tower will also have to be in excess of 100 feet =
just to keep the silly thing off the ground. Now imagine the antenna =

privilege area (about a 4 acre plot) He has a 150 foot tall tower, a =
boom that is 80 foot and the rotator is a custom 1 HP electric motor =
with a reduction gear box. I am not sure he is still on the air. the =
last time I got to check the thing out was about 20 years ago.
