Aaronia Spektran review (the DB measurement device)

!DISCLAIMER! - ORT sent me some antennas for review, you can buy them here
Banggood sent the Foxeer Lollipop 3
I DONT use affiliation links - I'm not a sales guy, here you get HONEST reviews and opinions.

My test-setup:
I use 1mW on the transmitter, 5m distance to a VERY SENSITIVE receiver (Aaronia Spectran HF6065 -150dB!) and take enough samples from the -DB reading on the display to get an average.
The VTX is warmed up before the test - this way I can be sure it stays at the same output level for all antennas. This is not 100% accurate. On start I had 815uW and after 1h testing it showed 1029uW or 1mw - but this should not impact measurements too much!
