Advice on constructing half wave dipole with reduced velocity factor for site that is not quite big enough?
Velocity factor is something that applies inside the coax, where the fields are all inside the dielectric medium. Antennas in the air are not subject to "velocity factor".
A plastic coating ...

Advice on constructing half wave dipole with reduced velocity factor for site that is not quite big enough?
Since each leg of the dipole is a 1/4 wave, electrically, I imagine the antenna design you're contemplating is a fairly lossy design that happens to give a good match. As far as coils, they always ...

Advice on constructing half wave dipole with reduced velocity factor for site that is not quite big enough?
This technique basically works, in that you can get a resonant antenna at a shorter length than you would with plain wire. It's a form of linear loading.
But, it's a worse (lower efficiency) antenna ...

Antenna tuning confusion - help!
You are asking two questions, tune the antenna, or tune the coax/antenna system for low SWR. Or tune for best performance/tune for lowest SWR. They aren't mutually exclusive, but pretty hard to ...

Is a vertical noisier than a dipole, and if so, why?
I'd like to corroborate one of the other anecdotal answers: my vertical is both extremely sensitive and noisy. It picks up all kinds of noise from my suburban neighborhood, even with my entire house ...
