Hadley has the waterproof versions with silicon leads in 1m or 2m for
$20

re waterproof enclosure
Many years ago Telecom had sealed yagi antenna, which eventually needed
servicing.
When the riggers took them down they had a large quantity of water
despite triple O-rings and grease on the fibreglass shroud.

The solution was to drill a hole and fit a small diameter rubber tube to
act as a breather and drain.

I'd suggest using a larger dia rubber tube, sealing the end with a
flexible cap and cutting a small slit, so any water can escape, but
wildlife can't enter.


Hadley also has a I2C temp and humidity sensor which may suit.
