Great distance with my P4P but I do have line of site in country setting in North Alabama, No mods, no antenna booster of any kind have done this flight 2 different times, I keep my controller on auto and it chooses the 5.8 and at some point over half way there it looses connection on the video so I switch it manually to the 2.4 and it regains connection, never drop in the controller signal just the video part of it.
Here's the tradeoff on 2.4 versus 5.8 (in the USA anyway). The 2.4 band has only THREE non-overlapping channels to chose from in the USA - 1, 6, and 11. All the rest of the 2.4 channels overlap one of these three. In a populated area, even a normal low population-density residential one (maybe especially in a residential area) - your aircraft and controller are going to likely have a hard time finding a good channel to communicate on.
With 5.8 you get more "non-overlapping" channels to choose from (in a usual residential setting) - so it's much more likely that your aircraft and controller will find a relatively clear channel to use.
So use 5.8 all the time, right? No.
The flip side of the coin is radio propagation characteristics. The lower 2.4 frequency propagates better than the higher 5.8. That's why some users report losing signal at 5.8, switching to 2.4, and regaining signal.
I also find that the "auto" mode (where you let the aircraft and controller decide to make the 2.4 versus 5.8 decision) often makes terrible choices. My last flight was in an area where there were many, very strong 2.4 signals nearby - but the 5.8 band was wide open. The firmware chose 2.4 and reported the "poor wifi" warning. I switched to 5.8 by hand and had a perfect flight.
So it's a tradeoff - as most things in life are. But if you know the good and bad points of each band, you can make better guesses about which one would work best for the flight you're about to undertake. |
