Topband: Common mode chokes

[doktorij at bellsouth.net]

I've been using a red Folgers Classic Roast for three years now at the base of my vertical with no signs of damage. I'd be surprised if many TopBand antenna installations, at least at my level, stay in the dame configuration for more than a few years. Seems we all like to tinker with 'em.

Bill noted painting as another option. So far the only exterior boxes I'm had to paint were made of fiberglass. It seems they only take a few years of weather before they need attention. Probably need to treat them like a boat and do annual treatments...

So far, when I can find them cheap, the best general enclosures are grey PVC and stainless steel. Finding the "right" size has been a challenge, usually waaaay too big or just a smidge too small hihi
