These two statements are conflicting. If you're going to have a StepIR
that will go down to 40 meters, you aren't going to want a Ham IV on it.
That's way too light, for this country anyway. In fact, a T-Twister
isn't enough for that. If you were going to limit it to 30 and above, I
might go with a T-Twister, but I really feel my TH7DX tri-bander puts
mine through more than it wants. It needs to be rebuilt now and then.
StepIRs are heavy too, at least the ones I've seen. But you're right.
It's really nice to have the tunable frequency range
Did you follow his link? He's got tons of space and can put up wire for
anything out to 160M dipoles, with a single support tower or pole.
Further, he can go almost any direction with wires without having to
weave in and out of tree branches, etc. I sure wouldn't mess with
anything like a G5RV or OCF in that situation. The gold standard basic
antenna on the lower bands is a simple half wave dipole. He's got room
to do that down to 160M. Why go with less? On upper bands, a ground
plane does wonders, but a simple 3 element yagi is excellent.
