[Antennas] Return loss bridge.

Sun, 26 May 2002 00:25:30 -0400

       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)
