No twin lead, there is a coax that comes from the antenna, so it's not THAT old, there is one very long bar that is broken, this should be the lowest stations, and the lowest channel (ch 2) is less then 15 miles away, at 110kw, it should come in on a paperclip.  The next one is a now digital Global repeater which is 21 miles away (Azimuth of 161 degrees), third is an A channel repeater (Azimuth of 184 degrees), which is 44 miles away, and it comes in, but without sound.  I figure if I can point the antenna at about 175 degrees, they should all come in clear as a bell.  I have a couple of other things I might try, I think I have 50' of RG6 here somewhere.....  I wonder though, if as usual when Global went digital, they didn't do something stupid, like cut power from 44kw to 4.4kw.....
