In this video I take a look at a 778D Dual Directional Coupler that was part of a lot I won at auction - I really wanted 1 but ended up with 6 - 3 of which didn't pass manufacturer perf test - So I thought I'd take it apart and have a look inside.
The Standing Wave Video can be found here • AT&T Archives: Similia... - Go watch it, it's awesome.
