That's the $64,000 dollar question. If you're doing long-range jollies (way past Line Of Sight): you will get attenuation and then signal dropout.
If you're getting signal attenuation at closer (and regulation) range: then D-H FCC BOOST will increase your signal strength to a noticeable degree but also leave it
just within the legal maximum transmitter power defined by the FCC.
Certain
Mavic 2's do have problems with really bad signal attenuation at close range - usually on the default wavelength (2.4 - 2.48gHz). You can counter this by manually switching to 5.8gHz in the transmission tab. This will give you a good strong control and video link
when flying LOS.
