I am looking at buying a P10K but am unsure of the proper shaft length. It will be mounted on on the mirror a Kenworth T800 with low mirror arms. I have heard that the coil should be higher than the roof...any truth? Also the predator stud mount uses terminal style coax connections...what is the benefit? Will a regular heavy stud mount work as well? |

I run a P10K with 9 in. shaft. It has a 5 ft. whip and must be tilted forward about 45 degrees to keep it out of the trees. This is a great antenna, LOTS of bandwidth. So long as the coil is 18 inches or more away from the cab it shouldn't be a problem. Mounted low might make it somewhat directional though. If you have the plastic fairings over the fuel tanks you might have grond plane problems. |

A bud of mine is using a dual coil 10K on his long nose Freightliner. It tuned at 5 and a half ft and does him a great job. A single coil will work but tune much longer. |

Yes I have the dual-coil version also----and it performs well. It has been on a 2006 Freightliner Columbia OTR rig. A 10K rep. says that it performs a little less than their single-coil "comp" version, but not enough to notice for the "average" driver. I like it.
The dual-coil is mainly designed for the "Big Truck" to begin with---to help with a large truck's usual high-mounting location. My shaft length is 30-inches from bottom to top/stinger insertion point (this includes dual-coil section of course), and the stinger is cut at 25-inches for my particular tune.
As a footnote----I've really found that the best place really to mount such an antenna as this is behind the sleeper/cab. It has/provides the most metal-mass below that mounting location. Mirror-bracket mounting is a pretty poor location to start with, with virtually no counterpoise. Most mirror brackets are powdercoated nowadays and are not connected to any metal at the cab because of nylon bushings. Moving the antenna to the rear of the cab made a huge improvement. |
