Did anyone done any measurement on video transmitter power and compare with what the manufacturer claimed? I did exactly that using a Agilent spectrum analyser. Below are the results.
Brand Spec Pwr Measured Pwr
BOSCAM TS832 #1 600mW 302mW
BOSCAM TS832 #2 600mW 363mW
ImmersionRC 5.8G 600mW 540mW
I can get min 1.6km range with iImmersionRC. However with exactly the same antenna setup BOSCAM only provide less than 100m range!
Anyone have similar experience?
