Comparing that to the ~20 ohms of the Hustler and bugcatcher leads me to
suspect the difference is in the loss resistance which is consistent

observed performance on the air.


There's something wrong with the bugcatcher feedpoint impedance
unless there was a matching coil, cap, or transformer at the base.
Did you have any coils shorted out on the loading coil for tuning
purposes? Shorted coils lower the Q.

Nope
Just the Hustler base, the entire bugcatcher coil and a 103 " whip.
I expected it to be lower in impedance at resonance.
Now I've ordered a BBS screwdriver to see if the copper base is better than
aluminum.
Copper has about a tenth the resistance of aluminum, we shall see.

What bugcatcher coil was it? Obviously not the big one. Is the
Hustler base the one that hinges? If so, it might not be
conducting properly.

Yes it is the "big one" but I suspect that, since I cobbled it together,
that R is a big issue.
I don't care since it isn't a realistic solution. I used it "parked mobile"
in 1970.
Comparing the Nott with the Tarheel should be fun.

Yes it's the big one; I suspect dirt in the threads.
It's an impractal monster anyway.

H.,
When you find out that the aluminum/copper base
makes no difference at all, can I have the one you
don't want?

So you have done the measurements?
And no, I'm gonna run two screwdrivers; Then I can talk to myself.
