Clint, I would recommend plastic. There are circumstances where one side of the balun output can be grounded (think vertical antenna), and under those conditions, there is a chance that a metal enclosure will connect one of the balanced legs to the coax shield - that will bypass one side of the choking impedance and render the balun ineffective.
If you are careful to avoid the circumstances mentioned above, then either metal or plastic can be used. 73, Don W3FPR On 11/9/2012 12:41 AM, Clint wrote: > I just received my BL2 kit.
