I would be interested in what the 2.4 would have done. I appreciate your honesty, i am a newbie also to this technology and would not feel comfortable about tearing my controller apart. That being said mine is only 1 month old. I love my little Mavic Air, but i am looking at a 4w upgrade when the battery life gets there. Thanks for the post i truly enjoyed reading it.So I ordered the control antenna and a set of their 9db whip antennas. They are 14” long by the way. When you get this stuff in the mail it all looks pretty amazing. Some people could care less about the packaging. My thoughts are if you care enough to pack it and present it nice then you probably put that same attention into whatever is inside the box. For this antenna you have to modify your remote a little. You remove your factory antennas and replace them with little jacks. I was pretty stressed about tearing apart a $300 dollar remote. The stress was uncalled for. I watched the video they have as I done it and it was pretty simple. I got it all together pretty late but I had to take a test flight to make sure my controller still worked. First off let me say this. I’ve been trying a lot of test flights from my house checking distance in 2.4 and 5.8. With and without the little cheap parobolic deals you can stick on your stock antennas. So I know pretty much the distances I was getting going north and going south. I live kinda in a small valley and there are a ton of house so I get a ton of interference from my house. That’s why I’ve been looking for some kind of range extender. I always do better in 5.8gz so that’s the way I ordered the control antenna in 5.8gz. All my numbers will be at an altitude of 350ft. So with stock antennas to the south(the most congested direction) I usually got about 2800-2900ft. Same set up going north I got consistently 4300 ft. Before you tell me you get 13000 ft remember I’m in a hole basically and surrounded by trees. So far I only got to take a few trips with the control antenna. Two trips to the south, first trip I got 3450. Second trip 3500. I’ll be honest I was disappointed. I will say this. This thing looks so bad *** as long as I didn’t get less range I wouldn’t think about getting rid of it. Ok so I had one battery left and went to the north with it. To the north I got 5800ft and I didn’t lose signal but it was almost dark so I turned around. I was just happy to see that A. I didn’t break my controller and B. I did get a significant increase in range atleast one direction. I know this isn’t a ton of info but when I was shopping this is the kinda of numbers I was dying to know and couldn’t find them anywhere. Let me add a few things real quick. As I practice I’ll keep putting my results here. I’m sure things will improve. I rushed out to try it so although I already feel like it was worth what I paid I feel certain the numbers will get better. I haven’t even tried the whip antennas. As soon as I get home from work tomorrow I’ll be trying those out. And I have to add this about the company. They are pretty awesome. They have answered a ton of questions from me. And have always answered very quickly. Also, I told them my situation and they tried to tell me to get the powered version they sell. It’s called a switch. And I do intend to but I couldn’t spend that much right now and didn’t want to wait. I’ll pay a little more buying everything separate but I’m cool with that. I just wasn’t patient enough to wait. So if anyone actually cares about any of this hang tight and I’ll try to share my results as I get them. But so far for what I have in them I’m very happy with them and would recommend them to anyone. More to come...
