Hello Folks, Is it possible to use NIC to overcome losses in terminated loop antennas? If so, how would one measure the NIC input impedance with say a Signal Generator and an Oscilloscope to check fo
I'm probably not the only one...please define NIC. That comes up in my head as Network Interface Card. 73, Guy. _______________________________________________ Antennaware mailing list Antennaware@co
Guy, NIC stands for Negative Impedance Converter. These are active devices that have a negative resistance i.e. the voltage is 180 degrees out of phase with the current. They can be uses to cancel ou
Hi, Andy. Thanks. However, attachments do not make it through the reflector. Please embed the link url in the text proper and resend. 73, Guy. _______________________________________________ Antennaw

It seems to me that I have seen stuff like this, but it was never referred to in your terms. It is an old idea, back into vacuum tubes, as mentioned. The devil has always been in the details, and whe

Andrew, It seems like you could put a resistor of the design "-R" value in series with the input of the NIC and check for a short circuit. If you're thinking of using this to cancel the resistive loa
