Also, to the OP, if you're interested in playing with this some, even
just to the point of seeing what some of the radiation/reception
patterns look like (goes-out signal strength is the same pattern as the
goes-in sensitivity, btw) hop over to http://home.ict.nl/~arivoors/ and
d/l a copy of Arie's version of the 4nec2 antenna modeling software.

There are example files that are similar to typical TV antennas, among
others. You can get a list of channel assignments versus frequency on
Wikipedia.

Hi - I need to receive VHF TV (channels 6,7,9,13) and would like to
make a super-duper antenna for inside my attic. I would have thought
that I could easily find (simple) instructions on the internet but
can't. Does anybody have a simple idea that just uses wire (wire
should be easy to attach in an attic).

There was an article in Electronics World in December 1967 by Harold
Pruett titled "Designs for Log-Periodic FM & TV antennas". He used two
lengths of hookup wire, attached to a wooden frame in a zigzag
pattern, and gives all the dimensions needed. I built one then and it
has worked fine ever since, though now there's nothing to receive in
this area so I've switched to a UHF-only antenna in the attic. I can
mail you xeroxes of the article. I'm adouglas (at) gis.net.
