[ARC5] Collins stuff and RCA jacks

Why didn't Collins use a BNC connector? It's better mechanically.

It has been proven repeatedly that the RCA jack has a lower (like none) 
impedance "lump" than an SO-239, is easier to use (no cross-threading 
problem, doesn't vibrate loose), and is fully as capable at the 100 watt level. 
Furthermore, those insulated with ceramic are even better.

There is absolutely nothing wrong with the RCA jack in RF service at the 100 
watt level with small coax, especially when good quality ones are used.
