The following is a summary of replies I received in response to my inquiry
on small outdoor enclosures for beverage transformers. Lots of great ideas.
Right now I am leaning towards the gray PVC electrical boxes sold at Home
Depot. Physical size and price are about right for my application.

Thanks to all who replied!

> Take a look at the little grey boxes that WX0B uses on his baluns.  You can get them at Home Depot for about $5 to 7 dollars.
They are tough and have a gasket to seal them.  I also have had good luck making cylindrical containers using schedule 40 PVC and
pvc cement.  I like the boxes better though.

I have been using Radio Shack mini boxes for over 20 years now and some of
the 9 to 1 beverage impedance transformers I built then, are still in good
shape, according to the usres.  See me at 1.865 khz after dark.  Willy K3VW
