OCMike doesn't do FB so I'm posting here. Design freq is 444.500, I cut it a little long but still ended up with great numbers.
SWR 1.5 down points.........
437.000
456.500
Best was at the mathematical middle 446.500 1.1-2 or so
Note the ultra high tech matching network. I used about 12 ft of RG8/U mini foam for a feeder. This is #6 solid copper grounding wire I bought at Lowes.
