You will need to get a different mount for the predator antenna as it has a 3/8" bolt type screw that screws into the mount. Where as the sirio is a pl259 connection. When buying an antenna, remember height is might. At nearly 7ft the performer 5000 is a pretty tall antenna. To get the same type performance should require an antenna of equal or taller proportions. The predator 10k is a good antenna and I'm sure the bad to the bone one is too. Just some Info to help hopefully. I have worked most of the world with my mobile setup, sirio 5000 per. Mag mount, optima mk3 and a magnaforce 350hd, (same as the tnt350hd). Normally don't run the amp if not needed. Have made contact to AU while driving down I-4 at 70mph. Get the Breedlove puck mount and the sirio performer. Probably will have to trim about 1/2" off the antenna to get it to tune correctly, they normally are a bit long. Got my swr reading to 1.1 to 1.2 across the cb band. I'm sure if I put the analyzer on it I could get it near perfect. Anyway good luck and have fun.
