have tried atached the end of a coax cable comming from the tv antena
to the telescopic antena on the radio and that doesn to seam to do
much but i want to know if i can run a whire along the tv antena
towner that is metal and to my radio

what is the best way to seup an antena?

any help would be great thanks

You should endeavor to get the wire at least 5 to 10 feet off the roof.

Use a BALUN to connect the wire to the coax lead-in to your radio where
the BALUN ground is connected to the metal roof.

Conversely if raising the wire is a problem then keep it a few inches
off the roof and connect the wire directly to the coax center conductor
and the shield to the metal roof.

Well first of all your TV antenna will be too short to pick up shortwave
signals very well. You might try connecting just the outer shield of the
coax to the radio's antenna input and see if that works better.

I believe the ATS-505 is a portable radio, so you may want to construct
something like the following:

wrap some wire around the radio's whip antenna, and get the other end of the
wire up high somewhere. Or you may just want to get a wire antenna up high
and attach it directly to the radio's whip, but this may cause overloading
since most portables use a lot of preamplification to compensate for the
relatively short whip.

Oh, I see that you are talking about a wire along the TV mast. Depends
on how long the mast is if it worth doing. Chances are it is not long
enough. Better would be a horizontal wire across the roof.

OK, I seem to understand better now, too. I used to have a random wire that
was over 100' long and had the near end of it attached at the top of my
VHF/UHF antenna mast. It came down next to the mast (lead in part) down to
the radio, and I never had any problems with the mast affecting the signal.
Of course the main part of the antenna was up & away horizontal with the
mast with only 15' or so of the antenna running down the side of the mast.

If you think there might be problems with it, you could always put standoffs
on the mast and run the lead in wire down through them.
