No, actually that loop is for SW. It is a 1 turn loop with a 9.5-365
pf variable cap. If your run 1 turn loops of various reasonable
sizes through the calculators online, including Bruce Carter's, they
will fall in the SW range.
Using that calculator, 1 turn, 36" sides, gives 3.8 mhz - 23.6 mhz.
With 1 turn, 30" sides, it gives 4.2 mhz - 27.2 mhz.
If 1 turn, 24" sides, it gives 4.8 mhz -29.8 mhz.
MTM scientific has a 15 turn tuned loop, 17" sides, that covers the
I have photos of my MTM AM loop in the Photos section in the Loop
