Mike, The antenna feed point terminates at a four foot ground rod and then I am
running a number 14 wire from that ground rod to my existing radial field. That
run is about 40 feet. The radial field consists of 3 8 foot ground rods and
nearly 2000 feet of wire spread out over my entire front and back yard. I
didn’t want to run "new" radials over top of the existing so that's why I did
what I did. I am measuring SWR from the shack end of the feed line. My old L
was only 35 foot vertical. I thought 65 foot vertical would be much better but
sometimes the old L hears and transmits better by a couple S units depending on
where the station is of course. So I think something is off? Hopefully I didn’t
build myself an accidental dummy load? -Joe

It sure IS broadbanded. Couple of questions:

The ground is connected to the existing ground system for the old L.
Can you describe this?
<blockquote>
I get a 1.1 SWR reading from 1.8 to 1.9 before it moves up to 1.3 and slightly
higher to 2.0. The antenna seems to be working OK (relative to the old L). This
seems awfully broad banded?

Where are you measuring the SWR? At the feedpoint or at the end of the 125'
coax?
