    This really has nothing to do with CB but every time I see a tilted antenna it reminds me of the conflict between the Cherokee County GA Sheriffs Office and Clayton County GA SO. The FCC granted both agencies permission to use 158.775 as their dispatch freq. I live in Cherokee Co and quite frequently I'd hear Clayton on that freq. One of the directives from the FCC was for Cherokee to tilt its transmitter antenna a few degrees. You can find the full directive on FCC.gov. Easy to Google

    Interesting that a small tilt of the antenna would prevent same-frequency conflict.

    I'm puzzled why the FCC would approve the same freq 40 miles apart

    Because of the radiation pattern within the area. The same goes for other services.

    Seems like a risk to approve the same freq so close together. In this case they obviously got it wrong and put lives in peril

    Not really, there also is a issue with the application from the counties, some have single frequency use for adjacent counties for operational reasons.

    Is it your position that when neighboring police dispatchers accidentally interfere with each other it's "not really" a problem? If that is your position I'll know what I'm dealing with.

    "some have single frequency use for adjacent counties for operational reasons.."

    Not in this case

    Yes, someone screwed up. You can't have the same freq used in neighboring parishes (or counties for you weird folks). They're going to step on each other. Tilting antennas does nothing but change the radiation pattern and makes reliable communication impossible. It makes for dead spots. Not good advice.
     
    Timin770 Thanks this.
