Alrighty folks I need to big time help with my antenna mod, trying to isolate down what part is the issue but frankly I’m pretty unhappy. I bought the cleaninstall controller adapter kit from maxx UAV. Instructions were ok and part seemed fine. I reinstalled and verified the cable to mother board connection twice but my base line controller range decreased drastically. I emailed Jake at maxx Uav to workout issues with install but haven’t heard response in months.
So I have a run a lot of tests here to help isolate, hoping someone smarter than me can help find the culprit. I’m about ready to just buy baseline mavic controller and give up the MOd.
I bought 3 antennas all pictured in attachments. For post sake we will call them 7 dB (pannel antenna) , 5db (came with amp and shortest), 15 dB (longest).
First test I did was with each antenna over the same course i have flow with non-mod controller. Results were abysmal.
15 dB- lost track and signal 50 for above ground . I moved antenna and made sure I wasn’t pointing at the drone due to pattern . Still no difference.
7db - best result, naturally had to point at it, went about 70%of range of stock antenna and then lost signal
5db - was 2nd best and went about 40% of range of stock antenna.
No antenna- controller sees drone and video fine on ground but obviously doesn’t work greater than a few feet away
All this made me initially skeptical of two things, mother board connection /insertion loss of Maxx Uav kit. But verified solid mother board connection by opening controller back up. No way to verify antenna quality other than cutting them open. Maybe invest in $$$$ antenna with verified Db?
Second test I did was with the amps. Not impressed at all. I did the test with 2x amps on each rp sma. Verified power was on and put each type of antenna on the kit for the test . All had the same result . Lost signal at 50ish ft. This tells me there was huge insertion loss with no gain. Only two things I can think of to cause this:
1. The mini connector cable from controller to amp is garbage and bleeding all the signal strength so there is nothing to boost when it hits booster
2. There isn’t enough bolts going to booster. It’s advertised as up to 16volts. There was zero heat sync issues when they were powered on. This made me wonder what volts or power were going to the amps . I used stock power supply from kit . Is this enough power?
Also looking to make a mobile kit, but don’t know how to power both off one battery and how to control voltage via rc style battery. Any product recommendations
? I currently have what is below in pics but it’s one cable and frankly I haven’t gotten it to work because power pin isn’t small enough .
Really hope the forum can help me out here, lots of questions folks!
