Are you saying a recieve antenna tuned for 49 mhz will give the same
meter reading from a 49 mhz antenna as one tuned for 27 mhz. If that was
true why the different need for recieve antennas just hook up any length
of wire. Now will it be a night and day difference I don't know but here
you have a guy testing antennas trying to eliminate variables, looking at
a meter on a 31" tv. Is that the best you can do is argue this point? why
not tell us how max FS doesnt mean lowest SWR.

How dense...or is it argumentive can one be? Let me clarify.

The receive beams gamma was adjusted for a best match around the
CB ssb channels. A typical way to set up a antenna.

The transmitting antennas where all set for the best (nulled) SWR
at the same CB ssb channels. All the antennas achieved a 1.5
to 1 or better match at the SWR null. A typical way to adjust a
antenna.

Even if I replaced the resonant beam with a coathanger the S-meter
would still yield the same gain ranking of the antennas.
