Good grief, they have left hams behind! That's close to an HD series plug in coil, of which I have several. For 160, i wound AWG 10, stranded, on 3" PVC pipe, works fine. I could even sell you an HD jack bar. Somewhere, I have a big old Johnson roller coil that, I think, gets to 25uH. The 2404 is 32uH. Wilson W4BOH
