Mainly laziness. But also, the more I do something the greater the probability that I'll eventually screw up. There is a chance that if I install / remove the mast for every trip, at some point I won't fasten something correctly and it will come loose while I'm driving down the road. Or I'd forget the thing and leave it at home. So as long as I think it's safe I'll leave it on the trailer.

No, I'm afraid you would have an impedence mismatch. The TV cable is 75 ohms, the antenna wiring for the cellular amp is 50 ohms. This would cause problems like reflection of the signal in the line. You need to connect cellular stuff with 50-ohm cabling.

I agree with Jim - knowing to ask shows wisdom.

It's certainly possible. Unfortunately, when you go to get adapters to make the different cable connectors go together, they will probably be difficult to find, because this isn't done. The problem is that all transmission lines (including coaxial cable) have a property called characteristic impedance, and it needs to match for the system to work properly. The cable used for television video signals (including "cable TV" and satellite dish to receiver links) is normally 75 ohm (such as RG-6 and RG-58 types of cable, and the F-type connector on them), and the cable used for other radio antenna systems is normally 50 ohm. The Escape's built-in cabling should be 75 ohm, to suit the intended purpose, but that won't match most WiFi and mobile (cellular) radio gear.

My Wilson Sleek has a 50 ohm antenna connection, with an SMA connector. You could presumably get an F-type to SMA adapter, but that wouldn't fix the mismatching impedance.

I assume that what was happening was that the mismatch of impedance killed so much of the signal that the net result was useless.

Edit note: Mike beat me to posting the answer, but at least the answer is the same (differing only in degree of detail).
