I have a freightliner Columbia that I drive for work most every day. Currently I have a predator 10k mounted on the mirror but am looking for something that I could put on top of the cab. I have heard and read a lot of good things about the sirio 5000 but I am wondering if someone can tell me approximately how long it will tune for 11meters. I want something that works well but that I dont break off in a month. Thanks.
