Long flight for a new guy

[Pete43]

I flew this morning at the Normandy dam. I've flown 1500ft with the stock antennae with no loss of signal. Today I flew a little past 2000ft and according to healthy drones, I got a great signal as long as I wasn't close to the controller. I did my first waypoint mission today and I had good video feed the whole trip. Isn't this a little far to keep a good signal? I've got a Argtek antennae to put on it but I'm worried i might loosen the connections if i change the antennae's...
I use Litchi now and I setup my missions on Mission Hub. I set it to start recording at the first of the mission but the recordings didn't happen and so I didn't set them. Is there a special way to save a mission?
Sorry my other monitor shows in my screen shot

I did a little trial and error and figured out why the camera wasn't recording when I set it to in a mission. You can't have camera snapshots or recording when it makes a radius in the corners while flying? Why is that? Anyway I turned off the radius'd corners and the video and snapshots work fine now.
