I guess you have a larger end capacitor (also called "end effect") due to the
larger wire. That's the same reason your "half wave" dipole is slightly shorter
than half a wavelength. The thicker the wire, the shorter the dipole. That's
why you have resonance at a lower frequency as you made the antenna with a
heavier/thicker wire..

Subject: [TowerTalk] 160 meter odditiy
I have been using an inverted l from my hdx 89 tower with much success. It is
made of #12 stranded wire and I have decided to upgrade it to something more
beefy. I removed the antenna which played at 1840 like gang busters and cut an
Identical wire #8 and put it up in its place. No other changes were made but
when I went into the shack and checked it it was at 1723. Anyone have an idea
why 2 identical wires would appear so different?
