Best tools for analysing Receiving (Active) Antennas?
(1/4) > >>
vinlove:
For transmitting antennas, we use SWR readings for checking the efficiency of the antennas with SWR meter.
But for receiving antennas, what do you use for the checking and analysing?
Especially for active rx antennas, what are the factors for checking and testing?

What tools are the best for the tests, checking and analysis of receiving and especially the active rx antennas?
wasedadoc:
A SWR meter reveals nothing about the gain of an antenna (transmit or receive) which is achieved through its directivity.  What parameters of receiving antennas are you wanting to analyse?
Berni:
Id say a directional coupler connected to a spectrum analyzer.

That way you can see how much of a signal is coming in and how much noise/interference there is around it.

Resonance for the receiving frequency.

Could it not be possible also just by listening to the signal on the radio?
