Mobile Co-Phase


any of the wilson trucker antenna's will do just fine. do not run the coax that come's with the truck they use a spilter box for the fm radio and cb. if you take the panel off where the air brake and trailer supply is and move the houseing that the air brake supply that's is bolted to the dash thats where the coax spliter is


just did a radio install in my father inlaw's frightliner couldnt get a good swr we had to run a new 75ohm cophazing harness and all went well after that.


good luck 73's

are you pulling a dry box or reefer/trailer?

karo,
i hope you didn't use 50 ohm feedline for that harness.

Well no I would not use 50 ohm for the entire feedling. Just 50 ohm to a T- junction then 75 ohm from the T- junction to the antennas.
and why would that be? Wm?

because you can't properly match two 50 ohm loads in parallel using 50 ohm feedline. 75 ohm feedline in odd numbered electrical 1/4 wavelengths is required for proper current distribution and impedance matching.

Hey sleepwalker, what ^ he said. :p
