Thank you to all, i appreciate all the help and ideas on this matter, any others, please chime in!!
After i get things in working order, i would like to know what caused it so i dont run into anything like it again!
Climbing gets old real quick, lol
No preamps are used, but when i tried amps, More troubles arise.
Power down=turn off 1 scanner.
Antennas are electrically insulated from one another.
If i put stock antenna on 1 mobile scanner, leave the other connected to a discone, and scan with both mobile scanners, the trouble is not noted. The only thing is, i do not get the distance i could with an external vs stock.
Thanks for multicoupler suggestion.
