  1. Best trunk mount I've ever used. review by Callsign: W2ROD, Rodney on 2/13/2015

    I have tried various other trunk mounts on my cars and others cars and this is by far the sturdiest and best made mount I have tried. The RG-316 coax used with this mount is state of the art coax, it beats the other smaller RG-174 coax hands down and is easier to run than the RG-58. My only complaint is I wish instead of 13.5 feet of coax it comes with, It instead would come with 15 ft of coax. It would make some of my installs easier. After I replaced a Comet CP-5NMO mount that I did have on my car with this mount I noticed right away that reception was clearer and gone were the little clicks and pops I got while listening to others talk. I highly recommend this mount if you are looking into trunk lip mounts.
