Many thanks to those who responded to my question regarding an 
Admittance to Impedance converter.
I have a further question. Since most of the measurements we make on 
antennas and transmission line require the answer in term of impedance 
why are there so many commercial instruments calibrated in units of 
Admittance, particularly at VHF and UHF. I suspect that it is because it 
is easier to make accurate variable bridge standards if they use a 
parallel arrangement; is this true
Regards

Peter, G3LDO
