There is an age old saying….
“If it ain’t broke don’t fix it….”
However when it come to radio work especially antennas there is nothing to stop you from checking everything over before the snow falls and the temps drop because its much easier to work on re soldering things and running new feed lines and cleaning connections now before you need to work with gloves on…
Would you like to check the connections on this array at -20c?
So if you have antennas out doors and your areas are subject to freezing temps then really think about checking everything that can break… BEFORE… it does break… Thing about your support lines for dipoles….. are your coax connections outdoors still watertight???? How are your grounds????
An afternoon of checking stuff now can give you a winter of fun operating from the warmth of the shack…
Hope it works out for you
