I have all sensors separated here. Rainbucket, T/H, solar and UV have all their own extended cables, length about 5-6m or so each. The connections done with waterproof 3M Scotchlock's, easy to add, cheap, and works just perfect, even wothout additional shielding. As cables i have used plain normal phone-wires, just remember to check how many wires each sensor needs first

Ex. the solar/UV-connections are up in my windpole without any more shielding than the Schotclock's itslef gives, this in our wintry conditions
