I'm on the 23rd floor of a building so I get
good signals.

Good deal, you can have quite the setup living up that high. I also have a 4:1
balun, for whatever reason...I only used it once and it went into the closet. I
got it out last week.

To you and the more knowledgable in here. What exactly would a 4:1 balun be
used for? I figured to string up some wire or dipole and be able to run coax
into your shack. I'm sure there is a better reason. ;-)
