You have choices here, and I don't much care for generalities that
unnecessarily limit the choices. Just because one person wants to use
a tuner, and retune after any QSY greater than 20kHz doesn't mean
another who wants to use a broadband system should be discouraged from
doing so.
Hi Tom,
The thread was "wire thickness versus bandwidth" As you know, to scale an
antenna from one frequency to another, you need to scale the wire diameter as
well. This will keep the bandwidth pretty much the same.
I thought I was commenting on the bandwidth as one changes the frequency and
length of an antenna, but keep the effective wire diameter constant. Of course
if you vary the effective diameter, 3 parallel pieces of #8 a foot apart on 1.8
mhz, you change the effective bandwidth.

unnecessarily limit the choices.
I did not mean to be general and limit choices, sorry.
