I know your field pattern and efficiency changes when you have more than one resonant antenna on a vehicle. What happens if you have a main tx/rx antenna dead center of the roof and another rx antenna 8 inches away? Both are the same type of cb mag mount antenna.
 

it will change the feedpoint impedance of the DE, completely distort the radiation pattern, create reflect issues and possibly destroy the front end of the receiver thats connected to the RX ant.
