I get 225 kHz between 1.4:1 points. 14.3 to 14.075. The entire band is
under 1.5:1 with the lowest spot being 1.2:1. Seems to work fine with
the legal limit. No loading problems with both the fb and gain
seemingly good. I do realize these are not precision measurements, but
I'm pleased with the results. Yes, I would like something bigger and
broader, but it is doing the job so far.

Hi Guys:
I just picked up a Hy-Gain TH-5 Mark I in a tower package. I notice that
the 2:1 bandwidth of this antenna is only about 250 KHz on 20m. I'm sure
this is why Hy-gain came out with the 2 driven element version in the Mark
II version.
I'm wondering if this is even worth restoring now. From the yagi gurus out
there, are there any clever ways I might get a bit more bandwidth from the
antenna (even 300 KHz would be better) without any major redesign? I'd like
to use it on phone and cw on 20m.
