[R-390] MB T connectors? Adapters?

You could do what we did in the lab when we needed a custom converter. We
would take two connectors and connect the center pins with teflon coated
wire and silver solder the bodies together.

It would take about a half hour to get things to line up nicely and to use
a torch to heat things up so the silver solder would flow. We created some
real weird connections, GR connectors to SMA, APC-7 to RS-225. For one-off
testing we would just use adapters stacked on adapters but when we needed
to make a test jig then out came the creative use of a torch.

The first (and only) time I ever ran across the MB was in the R-390A. I
hate the little things, if you are doing something special than make an
adapter from MB to SMA and do everything outboard of the chassis
connections with SMA. I literally have hundreds of short SMA cables,
adapters, attenuators, tees, diode detectors, etc.. for SMA.
