Thats hilarious, many hams have been crimping CATV soft cable for decades. I
started doing it with RG-11 in the late 70's and RG-6 a bit later and have
never had a problem from 160M to 70cm and running up to 1500W (1200W on 75
with RG-6 to a sloper). The clad center conductor is soldered.

As I said earlier try a RG-8X/LMR-240 connector. With the various shielding
combinations available some trimming may be required.

Proper preparation and sealing goes for any cable.

Not necessarily. If the cable is slightly oversize a good crimp can be had
by not compressing the ferrule too far.
