Re: Phantom 2 Vision 1.7 KM (5,600 Feet) Long Range Test
For FPV video range, the repeater is mainly for RX. The range does NOT make too much difference for a 1500mW or 500mW repeater. The key factor is RX antenna attaching to the repeater, and the TX power and antenna of P2V camera.
Imagine, when you hook up a 14 dB panel antenna to stock repeater (50 mW per DJI claimed), you may get 800-1,000M range. When you use the same antenna on 1,500 mW repeater, you probably don't have too much gain in range considering 30X more power.
If you further look into detailed spec. of ARG-1211 (AKA Docooler), the TX power of 802.11n is 25 dBm (~320mW, not 1500mW) as I recalled. I believe P2V is using 802.11n though no official spec. from DJI.
It is hard to estimate 2.4G FPV range since environment (mainly RF noise floor) affect the range most. If you stand nearby a high power RF noise source, you probably would not reach 100 meters range.
RemE said:Since you have so much experience, what do you expect the range is for the Docooler 1500mW repeater with 9db dipoles on it to be? Just looking for a educated guess.
