No at all but instead Scotchlok's to extend the orginal cables. Been in use and out without additional coating in finnish weatherconditions for 8 years now with success for both my UV and solar-sensors.

Be sure to check that wires in the final RJ11 are in the same order as in the original Davis RJ11. Phone cables can often be crossed and you don't want that.

Cheers Niko, ha ha, funny ya say that, i bought 4 rj11 couplers, they were crossed
easy enough, 1 side was the same as the davis cable, so i just pulled the pins out of
the other side and refit them in the correct order, i learnt quickly that you only get a
max of 2 goes at bending the pins to get them out and refit them.  The only way i can
waterproof them is to hot glue then electrical tape, amalgamated tape would be better.

I was hoping to find something along the lines of the Davis version but cheaper, i need 3

Phone wires seem to work on the "two wrongs make a right" principle, crossover in the cable cancelled out by another crossover in the connector  :lol:

Those scotchloks are quite small, they only need protecting from direct driving rain, so yes, tape to mast will work. For a bit of extra protection I would make a drip loop - u-turn the wire from the sensor back up the mast for a few inches so that the connectors are pointing up when you tape them.

Yep, thats the way i have done it too. Of course a layer of tape around the whole thing would give even more protection but the tape-packet would need to be 110% water/moist-proof then wich is in de facto impossible when 2 wires goes inside it. The experience from my own fiddlings togethter with our wet/humid/frozen fall/winter where humidity stays at around 100% for months are that no protection at all are better than bad protection.

Well, if you really want it weatherproof :wink:  Get a short length of plastic tube (e.g. pvc conduit), cap one end, fill it half way (or more) with hi-temp silicone electrical (dielectric) grease. Mount it open end down on the mast, u-turn the spliced wires up into the tube so that the spices and ends of the cable jackets are well in the grease. Tape/clip the wires to the mast, stuff the open end of the tube with rubber/plastic foam to keep it clean.
