[TowerTalk] Take off angle of yagi vs a wire antenna at about 30'

[Tom Osborne]

Hi David

When I go camping, I have a wire antenna that I use with my setup. It is 
about 100 feet of wire fed in the center with ladder line.

Sometimes I have a camp spot that doesn't allow me to put that much wire 
up so what I do is take a couple of 2-liter pop bottles and just wrap 
the excess wire around them until it will fits the spot. With the tuner 
and ladder line, it works pretty well and will get me on all bands.

You might just try putting a wire as long as possible up and feed it 
with ladder line with a couple of coils wound with about 30 feet of wire 
or so in each half to make up for the shorter length.  That would 
probably work better than the 33' end fed wire.  Never modeled it but 
just put it up and made contacts with it.

It is not fancy, but works for me when camping :-)  73
