Simple. Connect the analyzer output to one antenna, the input to the
other. Set the sweep range for that where you want to look at antenna
coupling (usually one band for which the antennas are used). Make a
sweep and tell the analyzer software to display S21 in dB. S21 is the
gain of a device
In this case think of the network analyzer as a transmitter with a receiver
tuned to the same frequency. Before testing you connect the two together and
normalize the receiver response to unity at each test frequency. Now connect the
transmitter port to one antenna and the receive port to the o
Hi,
That ought to be fairly straightforward. Connect one antenna to the the
output port of the analyzer and the other antenna to the input port. Then
set the sweep for the frequency range you want to test.

Yes. AND, more important, calibrations can be saved for standard

I use mine in the field all the time using a Win 10 touch screen tablet. The

I have one more suggestion. I have a MiniVNA Tiny, expensive at about $600,
but it is a full two port Vector Network Analyzer in a 2.5" X 2.5" X 1" box
connected via USB. It has both a computer app and a phone app to run it. I
have taken it out in the field where I would never consider taking a 75
The choice of analyzers is not that simple unless cheap price is the only
factor.
I have four analyzers: Rigexpert 230Pro, FA-VA4, VNWA3 and Mini60.
Rigexpert covers up to 230 MHz and costs about $500. It is the easiest to
use and has the most functionality. Less accurate because it does not have
John,
I saw that one on FunkAmateur/Box73, they sell the kit.
What appeals me is the price (155 euro), the simplicity the way it can
be built, the features, apart form being a nice graphical analyzer it's
much more like a signal generator from 100 kHz to 100 MHz. It's readable
