Hi all.
I need to test the gain of antennas before installing it.
I have panels, grid and parabolic antennas.

I need to test the effective gain for different tilt and azimuth.

did someone have hints of how to buil a test system ?

Thanks in advance.

Hi, make anechoic chamber with mast fitted with servo rotation system. Buy some network analyzer. This is not bad

Make measurement and calculate compare with 1/2 wave dipole.

how much are those R&S®ZVL6 ?

Something around 20k Eiro

how do you use them lol do you power up your anntenna and it tells you if your anntenna is broadcasting on high gain or low gain ? is their a tool to test if a sector is working or not?

You can check antenna quality measuring for example antenna gain or SWR and compare with producer information. In attachment you can see two same type different company antenna SWR
