I have the same issue as everyone else does with poor recieption from the radio. I took mine out and found 2 3ft pieces of wire connected to the radio. I was wondering that if a person could find the exact dim on the roof that a whole could be drilled into the wall cavity where a external antenae could be mounted and wire ran to the radio. sounds easy Maybe someone has done this already..I will wait to hear from them..My worry is hitting a hot wire in the ceiling...Has to be a better way..Dont know why Keystone just didnt drop a antenae wire down the wall cavity...Oh yea...MONEY !!!!!
