I have a W9INN 130' (or so) loaded dipole. Not bad. 2:1 VSWR bandwidth
appears to be about 25 kHz, but even a full-sized job is only about 50 kHz.
I'm using coax to feed it, but if I was serious, I'd switch to ladder line
and let my tuner expand its bandwidth more. Never tried the 71' long model,
but I imagine its BW would be quite small, maybe 10-15 kHz or so. I don't
know how much suds the loading coils will take before they fry, but I've
used a kW on CW (intermittent-duty) and they seem to handle that okay. Same
power on RTTY might create crispy critters....
