3-M impedance bridge?
 

Hi,

Does anybody have any experience with the above, as discussed in The
Antenna Experimenter's Handbook, by Peter Dodd G3LDO?

I'm planning to build a version, with a 4-channel A-D to take the
measurements, and display the results on the PC. A further stage of
development will be to add a DDS as the signal source, giving me a PC-
based antenna analyser.

Assuming I go down this route, what do people think about using the
voltage derived from input power (Ea if you know the circuit) as the
reference for the A-D, giving me a proportional figure for the other 4
measurements without having to scale in software? More to the point, has
anybody actually played around with this setup, and would like to share
tips?

Thanks
