Just got my new ARR SP432VDG preamp in the mail today. Since I'm on a budget, I opted to buy this unit rather than a mast mount outdoor amp. It is still my intention to mast mount this preamp though. Advanced Receiver Research themselves say that you can do this using a NEMA outdoor electrical enclosure. The problem is that I've been looking at outdoor electrical enclosures and have yet to find one that has dimensions that the preamp will fit in. I have really only been looking at outlet type boxes. Anyone have any suggestions as to what I can use? The unit is about 3 inches tall including the N connectors and about 4 and 5/8 inches wide. I need something relatively cheap that will give reliable protection. Thanks, Michael, W4HIJ
