Curious about the I.R.E. Standard Dummy Antenna
GREAT info, that's why I lurk here often.
Just one teensy question, though...is this polarized?, e.g. the 200pf cap is the receiver probe, the inductor plus shunt is the signal gen connection? or versa-vice? Thanks, Terry Bakowski [see you at the Peoria Superfest] H. P.

The "IRE Standard Dummy Antenna" consists of four components--- a 200pf cap in series with a 20 uH inductor, which links the signal generator to the receiver's antenna input. A 400 pF cap in series with a 400 ohm resistor is connected in parallel with (shunts)the inductor. |
