I have made a indoor/outdoor STEALTH of sorts, a Multiband HF LOOP Antenna,
approximately 540ft long (from center connector back around to the other
side of the connector). I am using 13 gauge - copper - stranded plastic
cover - wire! Does anybody have a velocity factor chart?

At the present time - my MFJ Antenna Analyser has it resonating at approx
10.5Mhz, and I am trying to get it to resonate at 1.8Mhz (160M).

I need the info to try and figure out how much I need to reduce the overall
circumfrence.
