Hello,
here is a Link to Alpha 2400C cable specifications.
http://export.farnell.com/_/dp/1619556Looks pretty light... 24 AWG
From the switch manufactures.
"the remote has been tested up to 150 feet using quality Alpha 2400C cable."

50 meters = 165 feet
If there "Braggin' " about 150 feet that may mean that it only worked
99.8% of the time at 200 feet. If it gives you trouble you could add 20 or 30
feet of heavy wire between the control box and the run to the switch
to get back into spec. It's a Crap shoot.
