[R-390] Re: R-390 Digest, Vol 10, Issue 23

Hi,

The last time I was in Skycraft Surplus, 2245 W. Fairbanks, Winter Park, FL
32789 (407) 628-5634, they had a whole bin full.  According to my old
catalogs, the correct designation for these connectors is type MB.

Hi,

Does anyone have a source for the mini BNC connectors
used on the R-390A RF deck?  I would take right angle
or straight.  I need these to build up a "as is" deck.

Please email me with any info.

Thanks in advance,
