Okay, you've got a good argument, the coax and balun are already up from a
previous dipole so I wanted to use them. I will get copper wire. I really
like the idea of a remote tuner at the antenna. I will be building an AT11
and may later, try to install it at the antenna.
If the loop is multiple wavelengths of desired bands why won't the
coax+balun adaquetly (not ideally) match to the loop?
In your opinion, would 300ohm line be better than RG8X? Without the balun
of course!
Remember it's fun to just experiment sometimes and climbing up and down a
ladder is good cardiovascular exercise!
