Thank you, Ralph

I'm sorry if I am giving inadequate information. Besides the basic
description of the antenna, I'm not sure what else to offer. I doubt it took
anyone long to realize that I am a novice and have as much info on antennas
as one learns for the Canadian basic exam, and and can glean from a borrowed
copy of the ARRL Antenna Book.

The only additions I have are that on closer inspection, the balun is Van
Gorden's (the manufacturer of the original antenna) Hi-Q Center Insulator.
Also, I am using an external automatic tuner, a Z-11 Pro by LDG. It
apparently tunes the antenna down to an SWR of 1.5, but doesn't have the
means to give a more accurate figure. My FT-875 displays SWR, as a bar
display, but when the tuner has done its job, the rig seems to display no
SWR bars, which I take to mean the rig sees a 1:1 or close to it. Still, I
guess that's no guarantee that the power is being used efficiently.

Anyway, thanks again for your help
