Actually, this model has benn floating around for quite some time - I don't claim to have created it. Someone measured the loading coil inductance and posted it. I'm using NEC2.

I don't claim it's accurate.

As with any modelling of antennas (and HFTA), I don't take it as accurate. I interpret the results as indications of trends that might be useful.

My old man made microphones. He sent them to an acoustics lab to get them tested. Here's how he interpreted the results:


"If it tests good and sounds bad, it IS bad. If it tests good and sounds good, it IS good!"
