In the U.S., General Radio is champion. But, in Europe we used a British
Wayne Kerr UHF admittance bridge on lines and antennas in the middle of
a high frequency broadcast plant with a dozen or more competing
transmitters on the air at full power, as they always were.

The secret of success is the bridge detector used. A Collins 51-J was
useless, solid noise across the H-F bands. A Hammarlund SP-600 worked
like a champ.

Hi Richard,

Interesting you mentioned the Wayne Kerr UHF bridge. In my impedance-measuring
arsenal is the Wayne Kerr B108 admittance bridge. The beautiful aspect of this
bridge is that it's unknown terminals are balanced, thus allowing direct
measurement of balanced lines.

My arsenal also includes: 2 HP 8405 Vector Voltmeters with HP-778D dual
directional coupler.
HP-4815 Vector Impedance Meter
GR-1606A
GR-1606B
Boonton 250A Impedance Meter
PRD-219 Complex Reflection Coefficient Meter, 20 to 1000 MHz

What would you like me to measure?
