On top of the cab is a stubby little antenna, from this antenna proceeds a co-ax-type cable, through the sheet-metal, to underneath the passenger seat; there is a ton of room under this seat.

The end of the cable has a two-part threaded fastener, much like a C.B. co-ax, but maybe 2/3 as large.

Under the seat, zip-tied to the cable, is an all-the-time HOT cigar-lighter plug.


I am thinking this has some kind of cell-phone application, maybe there was some kind of antenna booster, or maybe the guts of a big phone, that plugged into the lighter-plug.


Any educated ideas as to just what this antenna and power source may have been for ??


Thanks.

sounds like a cell phone booster like a smoothtalker.

Sometimes also used for VHF/UHF radios , my truck has one also.

If you take some pictures of the antenna and the connector on the end of the coax, I can tell you what it is. It could be anything. If the antenna is NMO mounted with a whip approx 3-4 inches long, then it's 800 mhz. If the whip is 5-8 inches long, then it's uhf. If it's 12-16 inches long then VHF. All 1/4 wave.

Again, a picture or two would be worth a thousand words in this case.

What is "NMO" ??

The little antenna stub is about 3-4 inches and looks possibly to have been clipped with cutters, instead of a finished tip.


I have never quite been able to get the picture thing figured out; that's something I need to work on.


Thanks.

NMO is a standard connector used for most mobile antennas. If the thing is 3-4 inches long, then it's probably an 800mhz antenna. Where did you get the truck from?

BearKiller

91 D-250 Cummins, it was a one-owner truck, we are second owner, the guy was a mechanic for a big under-ground coal-mine company in Eastern Kentucky, but retired probably 8-10 years.

Probably an antenna for a mobile radio.

Have you tried signing for photobucket.com and uploaded to there?

gps maybe?

jthorpe

GPS doesn't use RG-58 coax. Also a gps antenna doesn't have a whip. It's probably a 1/4 wave 800mhz antenna used for either an old mobile cell phone or two way trunked radio.
