The
SARK100 antenna analyzer I bought
also has the option to be controlled over an USB interface (other versions even
have bluetooth support). Over USB it is possible to automate the measurements
and have the results returned to the controlling computer.
For Linux software is available:
SARK100 Antenna Analyzer Linux Software
also via github with updates
coddingtonbear/sark-100-antenna-analyzer.
I cloned the git repository and guessed that the command to build a 32-bit
version would be:
koos@thompson:~/radiowork/sark-100-antenna-analyzer$ mkdir build
koos@thompson:~/radiowork/sark-100-antenna-analyzer$ cd build
koos@thompson:~/radiowork/sark-100-antenna-analyzer/build$ qmake -spec linux-g++ -o Makefile ../analyzer/analyzer.pro
This indeed compiled into a working 32-bit binary. Needed because the 'main
radio desktop' can't run a 64-bit linux. The laptop does not have this problem.

And after compiling the software comes using the software. It works nicely
and does what it says on the packaging.
