Can someone tell me to stop buying antenna's.Im new to this and have a cobra29(my first radio) with 2 4ft firestik's on my 379 peterbuilt currently.I was told not to skimp on the antenna because it is a big part of the system,so I went out and forked out the cash for a wilson 2000 trucker.When I switched out the wilson (1) with the firestik's I was told that there was no difference so now Im confused?I have bought francis also and still no difference I was under the impression that a good antenna would make a small radio(which mine is no mods)sound big and blah..blah...blah..I am willing to spend the money IF it will make a difference I mean is approx. 4 miles all I can expect to get with my stock radio no matter what antenna I buy?How does a 20$ antenna work as good as a 70$ (FIRESTIK VS WILSON)?
