What Magic Power does is simply tweak a bit of setting in the drone that determines the output power of the image transmission signals, not the remote control signals. MP overrides restrictions based on your location and allows for maximum performance possible.
The DBS antenna will more so improve your remote control signal, rather than dramatically improving the video signal (although some can do this well too). If you wish to further improve your signal quality overall, you can combine MP and the DBS antenna, however when using the mod you shouldn't change the output power past 20dbm (from memory, please correct if anyone knows otherwise) so you don't burn out anything.
Sorry if this comes across as confusing, but definitely ask for any clarification [emoji3]
Awesome thanks, so I'll probably need Magic Power as well as DBS then really.
