Jim,

Very well built.  I am curious about one thing.  Their write up states 
that this unit
uses 4  cascaded ferrite cores.  In the picture I can only see 2.
Thanks for sharing !

##  It has 4 x cores in total. 2 per stack.  It just isn’t readily apparent from the pix. 
However they do mention the use of 4 x cores in the write up. 

##  double braided teflon coax used, silver braids + center conductor. 
Not shown in their pix,  ( pix shows one per core assy)  but on the actual units is the use of two mounting
assys per stack, forget what they are called,  very similar to whats typ used to clamp bifilar rods to standoffs. 
Sorta like a white nylon  wrap around mounting strap, which is then machine screwed down.   It doesn’t
budge, even if inverted and shook. 

##  Plenty of mounting options on each end of the casing flange.  Bolted solid, or quick release. It’s a well 
thought out piece of kit.  Even though its  totally enclosed, water proof, and  UV proof, and zero ventilation,
I cant see it getting hot.  Both the Z + RS is sky high, through the roof on every band.
