I have the short pair. Holding up well. They are about 15 years old. Loved them enough to buy other non-satellite yagis ( for satellite use nonetheless!)
Maybe it was bad batch of plastic?!

Well I look my antennas over each year but they have always been relatively easy to get at even when they were on a glen martin tower on the roof, I could see every other year if it is a major undertaking but based on his call he is in New York, to think you can put a antenna up and ignore it for years in a area with snow and freezing temps stretches reason.
I'm also a fan of coax seal and some sort of coating on the elements, When I look my antennas over I'm checking for loose bolts and UV damage to plastic parts and coax, out on the west coast it is the Sun and heat that is the thing to worry about.

There is no mention of maintenance. Of course, it would be a good idea to check things out regularly. But, depending on where the antenna is installed, it could be quite difficult to get to it once it's put up. I can't think of anyone that actually does yearly maintenance on their antennas. My rule of thumb is to anticipate what problems could occur and do what's necessary to avoid them during the initial installation. I always use Coax-Seal and spray the heck out of everything with clear Rustoleum.

Might I ask what sort of preventative maintenance did you perform each year?

White plastic cracked and allowed water to ingress to the switcher. Customer service?? No return call. Pics on request.
