I have installed the ITElite DBS antenna and I flew with the mod today, I use to get 1.5 Km distance at 71 Meters height with the factory omnidirectional DJI antennas. I went the same route same height today but with the Itelite DBS and at the same point (as in the past with the factory antennas) at 1.5km my signal started braking up like it was doing with the factory antennas, then I climbed at 120M and got full signal, went up to 2.98Km eventualy with Itelite, when I lost signal all together at 2.98km and my Phantom 3 Advanced when into RtH mode. My mod was flawless (I have an electronics engineering background and had all the right tools for the mod) and I used silver-plated shorter cables from the SMA connectors to the ITelite antenna. I honestly hoped I would get more range as I was flying in a non-densely populated suburban area, is this ItElite DBS antenna not having any real effect? I am not convinced (however DJI states that with the factory antennas the max range is 1.2miles and I did 2.8km = 1.8miles today) Could it be the short silver plated cables that I used from Horizons, should I use the originals that come within the ITelite the box? Could it be the fact that I was recording at 2.7k and the power consumption of Phantom's CPU was draining too much battery to let the bird’s transceiver to work at it peak power output and gain? Could it be that there was signals degradation (attenuation) due to the fact that I was not on a hill or high ground but at sea level and there was small patches of trees along the route even though I was at 120 and up to 145m high clear and above the trees? How is it that you guys get these ranges (4.8 or 5Km)?
