HG beehive on a low voltage pin i hammered into the top of a clothes line pole, i had an aqua hemi 20 signal up here but a week ago i went to take it off the pin and somehow it split right in half at the wire ridge, I'm wondering if its because it rained and the temperature got down to 30 degrees one night. Did the moisture get into the glass and expand? if anyone has any insight to this it would be appreciated, i can post pics if needed :)
