The duty cycle of cheap PM motors is very restricted. Better at light load, but should be considered. Drum capacities are severely limited.
Wireless? Are you kidding? How will you feel when the wireless goes wild and two blocks your antenna up against the top of the tower? What will break first?
Never mind the anonymous programmers of questionable ability, what happens when you are swamped by RFI, ignition noise from the tractor, or hash from your HT!
Switches can fail too. I have experienced two runaways of a HF winch, caused by their crappy switch coming to pieces. I never operate my winch unless I'm standing beside the battery with one terminal loose enough to pull off by hand. Also, I've replaced the HF switch with two independent toggle switches of known parentage! One of my runaways would have pulled a small (40') tower over! FYI, Northern Tool small winches seem a cut above HF. My latest one, inexpensive, came with a beefy reversing relay, so there is minimal current in the hand held controller.
Reading again, always a good idea, it seems you are talking about the support cable. Sure that can be tightened, but where is the 250' stored? And do you really want a hot wifi remote controlled winch tied to the top of your tower by a 3/16 cable?
What about the traveler cable? The pros I've worked with use nice capstans mounted on their trucks. Very cool, as long as you pay 110% attention to the rope and its handling. If you let it jump off, you're in deep doodoo! I helped tram up some 500+ pound antenna assemblies, to 800', with 3/8 Kevlar line. The ONLY thing that kept the load from running back down was the guy on the rope! A one way grabber on the traveler loop (If there's a name, I don't know it) would have been a good idea, but they certainly didn't use one. I stayed out of the fall zone!
