TOP5

I heard two excellent questions in the past monts ( years? )

1. how may I connect an ammeter in the circuit, in series or in parallel ?
2. I think ... the loss signal can be measured with an ohmeter...


You may calculate the power loss, right, but you need a capacimeter and
not an ohmeter. Cut a know lenght of wire, measure the capacity between shield
and active wire. Apply the capacitor coaxial formula and found the
dielectric parameters. Use these parameters to found the loss at desired
frequency. ( is not the same between 100MHz and 2.5GHz... )
