In this comparison video I wanted to find out if the Black Pearl (all in one - Display with diversityRX) is compareable to the dedicated ImmersionRC Duo5800 receiver. On paper they both have 90dbi sensitivity. See in the second part how they look in comparison. For my test setup I seperated video TX and RX with a few thick walls at home.
Also I measured all my antennas with the ImmersionRC RF Powermeter. You see the values at 2:24.
The normal ones were affected by alignment (horz vs vert) and the SPW ones were "immune" to different alignment - as expected. The directional antennas had great antenna-gain in the cone and somewhat less optimal outside of it.
Btw. you can also measure the mW of your video TX. You plug a 30dB attenuator in between and set it in the powermeter. Great to measure the advertised milliwats vs the real output!
Sorry for this not being super scientific but it gives you an idea of the image quality.

►in case you wanna buy RCSchim a beer Thanks!!! ;-)
what is your personal pref for usage ?
what give the most effect or (the best result) for the least amount of money ?
I think everybody would be interested what to buy not to spend a lot and have the most fun
big thanks

if you only fly with gps stabilized Phantom2 or Naza quadcopters for aerial filming, the monitor might be the better option. you're not so deeply immersed but well aware of your surroundings, can check LOS what your copter does from time to time, etc.
than the TFT with diversity is best option.
if you use goggles anyways the diversity from IRC might be better (has 2 good outputs, better quality and is even more handy).
Sunlight is no issue with goggles...
I like both but I think will rather use IRC duo (maybe with the antennatracker) in future.
