Hello group. I am going to install a new setup in my 90 chev p/u with a stepside bed. All is good with a 225 amp alt. dual yellow tops, Lincoln radio, and a 2x4 (I have 3 to choose from, MF, XF, or DM, which one would you all suggest) amp. My only problem now is where to mount the antenna. I want to use a 102" whip with spring but dont want to drill big holes. Ive seen on a past post where someone mounted an antenna on the bed rail, center of the bed, behind the cab using a mount called "boss hawg". I feel this would be the best place for me. Anyone know where I can get this mount? Also am I going to have any problems with my antenna mounted directly behind the cab, ie: Higher swr, or not getting the distance, etc? I wish I could use my Wilson 5k mag mount but I have heard the coax would not hold up and I wouldnt get proper grounding. Looking for any good ideas. Thanks to all.
