hello. I just had a few questions about building 2m antennas.

This will be used indoors. I havent decided if its worth the trouble to
climb around in the attic or if I should just mount it on the wall. I have
vinyl siding so hopefully that is a plus.

My first is about the classic ground plane built on a so239 connector. I
went with #14 wire and soldered the center wire on no problem. My question
is whats the sturdiest way to stick on the radials? I have a 100 watt iron
and still can't get a solid connection for the radials.

I was also considering just putting up a vertical dipole on the wall. I've
heard people say they had better luck with the ground plane but maybe they
didnt have the coax ran off to the side far enough or just dropped it
straight down? It seems a little tricky feeding it from the center and
having the antenna vertical but maybe a few wire tacks can fix that.

As a alternative to the dipole on the wall I also thought about just getting
a connector and soldering the wire directly to it bent upwards and then
using some flexible wire for the ground and let it hang below the shelf.
Would this work ok being connected directly to the radio?

What do you guys suggest?

thanks
