Radio tech is a hobby for many of us. I've been building an improving radio gear since I was a kid, and admittedly, I have a fetish for antenna tech. Often times it's not the distance we are looking for, but rather an improved signal in wifi congested areas - or in my case, a better signal through the heavily forested lands of the Sierra Nevada foothills where I live. Your response demonstrates a lack of desire to fully understand the gear you use to operate your RC craft. I would think that many of us would be interested in learning more about the technology that we literally hold in our hands. By doing so, incidents where you may lose your video signal, while retaining flight control, would result in a calmer reaction, and the proper response to reacquire your signal without immediately hitting your RTH button.
If you own a Mavic, then you are presumably ok with Mavic's stock (best scenario) specs of a 4.3 mile transmission range, which is clearly beyond LOS. And again - YOU already own it. But, you are struggling with a 5 mile range? My brain hurts.
