Flying from the outside I would get choppy video when I got near the building.
Can I use a ferrite/torid(sp?) ring to help? Maybe if I got my GPS away from all interference on my hexa it could overcome the metal building limitations? I am fine flying ATTI in the building, just was hoping for some extra insurance because the winds in that building are insane. It can change directions completely in a matter of 5ft with the giant shop doors and fans and such.
I am pretty sure I will be buying a 600mw vTX today to see if more punch helps... I need one anyway.
Can't fly GPS like that. The receiver needs very critical timing data directly from each sat it sees, and if one or more of those are multipathed, your position can be from a little wrong, to hundreds of feet. Also you cannot use a repeater for all the above reasons.
For the 5.8, same thing. You are flying in a metal chamber generating nothing but multipath to the receiver and nothing short of very directional antennas on both ends will help (not fix) that. Al stronger Tx will make the problem worse by increasing the strength of said reflections to the Rx. In this case it's better to drop power as far as possible.
It would be interesting to see how many dropped frames the 2.4GHz Rx had?
Same when flying 5.8 outside. Often the breakup that people see is not signal loss, but reflections from nearby objects. And the building is a big one.
