Default suggestions for a limited space HF antenna.. vertical or dipole

Dan wrote in message . ..
I live is an area that really does not mind antennas however my home
and property are limited. I have about 70 by 130 feet an da coulpe
small trees about 25 feet high. I think my best bet is a vertical.


That depends on what bands you want to work, time of day you operate
and whether you're after DX or closer-in stuff (such as closer than
1500-1000 miles). Well-installed verticals are fine for DX but if you
want to ragchew on 80 or 40 they're not the best choice.

Also be aware that most manufactured verticals are severely restricted
in "SWR bandwidth" on 80 and to a lesser extent 40 meters.



I
also think i woud like one that states no radials required such as the
Diamond 80 to 6 meter CP6 vertical or somethin gsimilar.. Any
suggestions.. what am I missing ? verytical or diploe type or
somethign else.. Thanks for any suggestions


With a 70 x 130 foot lot you have room for a full-size 80 meter dipole
if the trees and house are in the right spots. 40 meters can be
handled by a second dipole in parallel at the feedpoint, or with
easily-made traps.

If your house is in the middle of the property and there are trees at
the edges or ends, consider putting some TV mast on your roof, vent
pipe or chimney, and supporting the center of the dipole. The trees
support the ends. If your house is 2 stories and you use 15 feet of TV
mast the center will be at least 35-40 feet up and the ends 20 feet or
so.
