Ok So I have a Panasonic tough book cf-31 along with a Gamber Johnson docking station in the vehicle. The toughbook has a built in Verizon LTE card in it. I recently installed a NMO mount external antenna on the top of my truck to increase reception. Past vehicles I have had had this set-up with the same antenna and it did increase reception noticeably. Especially in fringe areas. However this is not the case with this one. With the built in antenna on the PC inside the vehicle, I am getting around -71db. as soon as I plug it into the dock and connect the external antenna, it drops to -85db. I have tried two different antennas that I have used in the past. (one browning and one Pctel). both yield the same results between -83 and -85db. Signal jumps back to -71 as soon as I disconnect it. Same results with both rf ports on the docking station.
last night while in town with great coverage I did a download test and was getting 23 megs down on the internal antenna. as soon as I connected the external one, the speeds dropped to around 10 megs. I tried this twice to verify...same results.
I tested the antenna cable and it seems great. .02 ohm.. on both wires.. going to try to probe the docking station next. going to also try to test my PC in a different vehicle next week when I get a chance.
Any other thoughts or suggestions??
