What is a weather boot and why do you need one?

A weather boot is a little bit of rubber that slides over your cables or connectors. It doesn’t make them completely weatherproof, but it does keep the majority of water away. It’s totally unnecessary inside, unless you’re running your cables through a swimming pool or cold water line or something. But, it’s really critical outside unless you live in Death Valley where it never rains.

In parts of the country that aren’t total deserts, rain and snow are the most destructive forces to hit your outdoor electronics on a daily basis. The rain and snow themselves aren’t so terrible but the water they leave behind can be lethal. Water makes it easier for metals to oxidize — everyone who’s seen a rusty bicycle outside knows how destructive rust can be, and rust is just a form of oxidation. When metals combine with oxygen, they form new compounds that are generally weaker and conduct electricity less well. This is especially true with copper, the primary conductor of signal from your antenna and satellite systems. Copper oxide is a fairly poor conductor so avoiding it is very important.

That’s where a weather boot comes in. The most important thing it does is keeping water away from the little gaps and cracks in the cable and connector. The water that’s on the outside generally dries quickly but the water on the inside takes a much longer time to dry. The more time a surface stays wet, the more it’s going to oxidize, and the more it oxidizes the less effective it gets. It’s simple as that.

If you need weather boots, of course you can get them at SolidSignal.com.
