I'm guessing OK Don, Jim or someone knows the answers to this antenna
theory question.
For the telly, there are stations 60 miles more or less due West. There
are also stations about 170º from those, also about 60 miles, roughly
E-SE. In between there is a Propaganda BS station and a low power
UHF. I used a Maker coat hanger antenna (8 half pieces of coat hanger
arrayed 4 x 4 on a 1x4) for years with pretty good results,
considering. This winter it didn't seem to do much, even with a new
signal amp.
I bought a Lava 2605 directional antenna, and mounted it about 25' from
ground. It is a little better than the coat hanger antenna, but not
enough better to justify the price. I was going to buy the Lava 8008
omnidirectional, but lava said the directional would pull in stations at
a distance better. (it is aimed to the west stations) The signal amp
didn't seem to do much, so it is currently not in the circuit.
What I really dislike is that if I re-aim it to the ESE, I have to
rescan to get stations, and thus wipe out the stations we get from the
west. Not having set tuners kind of defeats the "advantage" of a
directional antenna.
Here's my question. Can I build a larger, better version of the
coathanger antenna for better reception? The half coathangers are 8"
I believe that was 1/8 wavelength or something like that. (maybe less)
If I built 16" wire loops or had more loops, would that be helpful? I
am pretty sure the increase of size would not result in a proportional
increase in signal. 10-20% stronger signal might result in less
pixelation and dead air.
TIA
