Subject: Re: [TowerTalk] Mosley Antenna Question
Tom,
You hit the nail on the head. Nobody said that XXXXX doesn't work. I
worked JA's on my Cantenna with 100 watts on 10m. You can work people
on anything. I didn't pull my tower over in favor of stacked cantennas
though....
People were saying there could be better options. I know the C3's I
have worked much better than the TH7DXX. Smaller, lighter etc... Do
they both work. You bet.

## A F-12 C3 is only 2 els on each band. Imagine that, 2 full size els
outperforming
a TH7DXX...which has 3 els on each band, 4 on 10m, and a longer boom.
## This is all old news really. 2 els, full size, only has aprx 4.1 dbd gain.
So much for
traps. A F-12 5ba has 3 els on each band, and will make lunch meat out of a
trapped yagi.
## Baffles me why M2 doesn’t make any multi-monbanders like F-12, optibeam,
and
jk ants. Just thought of something else. Putting a coil inside of an
aluminum cylinder
will decrease the inductance of any coil. So now you need more turns to get
the same uh.
Wind small gauge AL wire onto a grooved polystyrene form, encased by an AL
tube,
and you now have the worse possible config for a coil. Q of the coil would be
through the floor.
Try that on a tank coil in a linear to see the effect.
