Yeap. When installing an aerial installers should include what is referred to as a "drop loop" to make sure the water doesn't run all the way down if compromised. A lot of aerial installers unfortunately seem not to do this. Old installations get water in the cable. My old girlfriend's tv aerial cable was compromised by water making the signal poor.
Water's getting into the top of the antenna (where the co-ax joins the antenna) and running down the inside of the cable. This poses a few problems like
Risk of electrical shock
corrosion of the cable
lowering the signal strength
Best if possible to get it looked at right away, or if you;re planning on doing it yourself you need to seal up the junction box on the antenna and replace the co-ax...

Fire risk. Make sure when it is reinstalled that a drop loop is installed on the cabling if it isn't already.
Drop loops only work for water on the outside of the cable, on the inside it has very little effect...The water needs to be stopped before it gets into the cable
Once the water is in, you almost always need to replace ALL the cable, but a neat trick is to blow dry air through it for a few hours (use a vacuum cleaner or whatever) then seal the top end.
Great, ariel, water, all you need now is a washing machine :D
/me gets coat
Seriously, you'll probably need to get that aerial lead changed, since liquid ingress isn't good (and make sure they seal the joints and make a drop loop this time).
