Is it possible for an antenna to see through a thicket of trees? I
noticed a picture on a web site of a UHF antenna in an attic.

Yes it's possible. The signal will be attenuated slightly by the treesIs it possible for an antenna to see through a thicket of trees?

My TV antenna is in my attic and it works fine through the roof tiles.I noticed a picture on a web site of a UHF antenna in an attic.

Speaking of weak, at one time I laid the antenna and pole on the ground
to attend to something else. I happened to have a strong signal that I
had been looking at, and could see a somewhat dimmed view on the TV
screen. Strange stuff.
I would have guessed that leaves contribute to any trouble. I supposeOn 25/01/2011 19:53, W. eWatson wrote:

As I distantly recall, attenuation of a signal varies a lot by frequency
through leaves. Probably some frequencies have difficulties with the
atmosphere, etc. Dunno... There are probably charts on these things.

army personnel discovered that they could receive transmissions

of us on the western slopes of the hilly terrain could get a
usable signal. The reception at the house of a friend, though
facing west, was very bad - more snow than picture. There was a
medium-sized tree 100 ft away right in the reception path. I
thought that was probably blocking the signal, so they chopped
off most of the branches. The difference was quite significant.

Another not see through transmission of trees is Satellite TV.
