Default antenna among the trees.

hi!
i'm using a sloping dipole for 20m inclined at about 10 degrees off
the horizontal with my rig. the feedbond is not thoroughly collinear
to the rest of the dipole but incoming signals are very, very (many
many verys here) strong; rarely below a 9.

the thing is, the dipole at it's lower end is from just over my window
at about 50 feet up to a tree across from it. now i'm in a moderately
noisy environment, hospital next-door, rail tracks a building away on
the other side, and boxed in by buildings on 3 sides and a layer of
tall-trees closer than all the buildings.

a fellow ham said the proximity of so many trees have an adverse
impact on my out-going signals, but i'm not sure.

may i have the opinion of the group please?

regards,
abhishek.

I would not worry about the trees on HF. My tribander is at 40 feet. The QTH
is surrounded by trees 50 - 100 feet tall; yet, there have been times when
European stations have told me I had the strongest signal coming in from the
States.

Abhishek,
The trees will affect your signal to some small
extent, but so do the buildings around you and the
one you are living in. By the sound of what you
are hearing, it doesn't seem like the trees, buildings,
or whatever, are causing you any real problems. Unless
those strong signals are noise, in which case, those
trees are the ~least~ of your worries.
The 'ideal' location for an antenna is high above
ground and far from any surounding structures. Very
few people have 'ideal' antenna locations, almost all
are a compromise in some way. Yours doesn't sound
unusual, and since it seems to be working well, I wouldn't
change it (well, at least remember how it's arranged so
that you can change ~back~ to it if you do make changes LOL).
