Resonance and VSWR are NOT related!

My 75 meter mobile antenna is resonant at 3.94 MHz. My VSWR is 5:1.

You are measuring two different things.

The dipper is a very nice tool. I owned the Heathkit unit in the olden
days. I now use the Military surplus AN/PRM 10.

OK - I just bought a new in the box 1955 Heath GD-1B grid dipper
with the extra low band coil set. $25. The dipper works FB and I
used an old SO-239 chassis jack plus a bit of 22g wire and a cut
down pill bottle to make a 4t coupling loop big enough to "dip" -
that is I inserted the dipper's coil inside the pill bottle coil
attached
to my feedline.

Now here is where I make myself look stupid - My antenna's best
SWR is at 7185 with a 1.1:1 but the dipper showed max dip at
6990 (I tuned into the dipper with my K2). What's going on here?

Someone educate me.....lol
