I have a coworker that would like to put up a 40m antenna on his

and
while they are fairly satisfactory, I wanted to see what ideas the
group
had.

The approximate limitations are as follows -

o Boomlength 30 feet
o Element length 30 feet
o Any vertical components are max -10 feet from the plane of the
boom
and elements. The reason here is that it's a crankup, and his roof

clearance would be about 10 feet when lowered.

It would be desirable to have both CW and phone covered, but phone
only
is ok.
It will need to be coax fed.

Thanks.

So, no ideas? At all? I thought better of the group.
You are asking near impossibility, that is why there was no response.
QST had an Article on short, loaded beams, and W4RNL has written an
excellent Article on the same. Check those out.
Are you wanting to build or buy? This group, whom you don't think
much of, is mostly about design and building.
