I am very interested in building a return loss bridge to help with
antenna experimentation, especially in the VHF/UHF region. The
designs I'm interested in are at:
Of course, if anyone has other circuits they like PLEASE
send them along. I haven't found much beyond what I posted
above. I'm more interested in the resistive type rather that ones
that use a balun transformer.
I built a return loss bridge for 3.5 to 30 MHz with a type 43 ferrite
core and four windings.
For 146 and 440 MHz I use a lab type (Narda) single directional coupler.
Works great. (the only way to fly, short of a network analyzer)
