If it was an external source, he would be hearing it in HIS radio too. Now, duals are very directional.my dad's setup work awesome for everyone in front of him.but sucks behind him.Īnd, I don't know why we are talking external noise sounds to me like an internal problem whether it be a broken coax, bad connection, bad ground.but it sounds to me like it is in the coax, mounts, or antennas (and/or mounting).if he swapped antennas and it went away, that tells me he is on the right track with the antennas. He is using a Uniden PC76 with hot finals (I know, what a waste of $$) in this setup. Spacing really has nothing to do with duals as long as they are not right on top of each other.
He is SWR'd in at 1.2:1 and talks well over 25 miles on a clear night and depending on which way he is facing.I know, I was on the other end that night talking back to him. Try talking to someone when you are not moving and see what happens.Ĭlick to expand.This is so wrong it isn't funny.I have a set of no name 4' fiberglass true duals mounted on the fenders of my dad's 99 ram (I got them at a Flying J).same width as an RC. Also believe it or not but wind can have an effect.
I dont really remember but if you want to run duals like that and get the most out of them I would check into it. Those antennas are supposed to be 10 feet apart I think. Commonly enters the radio via the power leads but can enter via the antenna too.Ĭontact a local CB shop or ham radio club. Alternator - usually detected in the radio as a whistle or whine and follows the engine speed. Sorry, I don't know the name but the search engines on the web should help here. I have heard that some HAMS have had good luck with some very pricey ignition cables.$100+ for a set of wires but they have suppression built into them and the owners claim they worked well. I have read of people taking the braid off of coaxial cable and making sleeves for the spark plug cables, etc. Ignition system - the spark plug wires are like little antennas with a spark gap transmitter hooked to them. I have heard of some vehicle companies providing RFI (Radio Frequency Interference) filters to car owners who have severe problems. I have seen people use bypass capacitors on the power leads for the pump, near the point where the pump wires enter the gas tank. Fuel system - mainly the electric fuel pump and the injectors (the pump is easily detected as it causes the noise when you turn the ignition key to ON (not Start) and then if it is like most pumps, it will pressurize the fuel lines and the cut off). There are three main sources of noise on most vehicles that enter via the antenna.
