Yes. I learned this the expensive way. Be very liberal with RTH height.

I did the Alfa mod sort of "half-way", just the 2.4ghz antennas - I still have the stock 5.8ghz antenna - I was able to make it to 2500 ft out in the country flying over trees. Video was still going when it RTH'ed. Doing the 5.8ghz antenna this week, hoping to get a mile. However, I was very happy with 2500 ft, able to survey 80 acres, which was the goal!
