Default Dipole-2 different wire sizes?


"Joel365" wrote in message

I have a dipole with 134 feet of 20 gauge insulated copper wire. What
would happen if I wanted to replace one leg (67 feet) with 18 gauge
copper clad insulated steel wire but chose to keep the other leg with
the 20 gauge wire?

Hi
Interesting question.
As the others I don't think anything useful will happen.
In such cases it is convenient to put the things to their limits.
Imagine the diameter of one half is infinite.
You now have a quarter wave over a ground plane.A well known case.
Impedance is halved .
Resonnance is only dependant of the remaining wire and unchanged.
Your result should be somewhere between no change and that.
Another similar question :
Instead of burying lots of radials at the base of a vertical
what about digging (or using) a well and having a quarter wave of wire
dropped into it ?
