@BoRRoZ the cable plays an important role to, so yes I’ve tested cable+antenna with at least 6 db because I noticed that lower generator power gave wrong results.
Stop and think about that for a moment. With your setup you got different results at different powers, I would suspect some issue with the measuring equipment.
The antenna and its cables are passive, they should react the same (in proportion) to a power level of 10dBm as for a power level of -10dBm. If it were not this way you would have a situation where things such as antenna gain, VWSR and cable loss would vary depending on the power level in use ?
I test a F range from 100-200 mhz in steps of 1 mhz normally, that’s fine enough (and fast
The fancy antenna gizmo (N12101SA) uses up to 1khz steps.
I never meassured this (did you maybe ?) but the RF output of that rf95w when set to a certain level… how consisted is that level over the whole range ?
When I measured it with my RF Explorer, the output was surprisingly flat, although as is the case with most types of vector type analyser there needs to be a calibration step so that a ‘flat’ output is achieved for the purposes of the test.
