[Yaesu] RE: Silver Mica

[Jim Hargrave]

John,

I agree.

A very common use of coax is for building antenna traps. You can tape them
to the wire or tubing elements. I recently built an all band Trap dipole
wire antenna for my Son-N-Law. I wound the coils on 3/4in PVC pipe and used
Coax for the capacitors. They are easy to tune with a grid Dip meter and a
pair of wire cutters. I always seal the ends with a dab of RTV to keep
moisture out and keep them from sparking across.

I guess we got a little off topic...(:->
