Topband: Homebrewing Hairpin System and its Dimensions for my 160m T-loaded Vertical Antenna

[Jo, YC0LOW]

I am in the process to re-build my vertical TX antenna for 160m. Still
using the 18m Spiderbeam fiberglass pole. But I found its SWR and feedpoint
impedance values (using hairpin matching at feedpoint) were far from it
used to be.

Maybe I must make NEW  Hairpin System and its Dimensions for my 160m
T-loaded Vertical Antenna. I'd be grateful if you could send me practical
hints to rebuild that.

Also, I am willing to receive any advise for my new TX antenna. Having been
in illness since April 2012, I'd like to reborn on TB, this season, hi hi...
