Topband: Beverage transformer enclosures

[ZR]

Ive built them in both plastic Hammond boxes and PVC pipe with caps.

Both have survived up to 30 years in NH weather. The ones I took apart last 
year when I went to binocular cores and 2 wire Beverages were completely dry 
with no sign of ever being wet.

Of course the pipe cap version had to be cut open.
