[TowerTalk] Chokes, toroids and coax (Oh my!)

[Steve Maki]

What I've been doing for venting 4x4 or 6x6 PVC boxes is to drill a big 
hole in the cover with a hole saw, like 2.5" or 4". I take a square 
piece of plastic screen repair material that is slightly larger than the 
cover, and sandwich it between the cover and box. Voila, a nice large 
vent. Of course the box must be installed cover down.
