Well, I can't find those darn U.FL connectors so the factory aircraft antennas will have to wait. I put the bird back together and started to test external antennas.

I started with the circular antennas I found on eBay. This did not go well, I took off and 20' up and already at 3 bars of signal. Those were a fail. I suspect the merchant mislabeled these as 2.4, but from the size they look like 5.8gHz.

Then I got this error below. I have never done this calibration so I will go look it up now.

Once I get her flying again, next on the menu are these 6dBi gain omni's.

Beautiful..just gorgeous!

It seems like just about any type of antenna would work better than the stock inboard one.

you may reach out to the talented amateur antenna builder and personal friend ( I only say amateur because he's not publicly known) @procharged97 .
he could prob build you a set.

You guys all need to get on Ham radio so we could all talk together. That's another not so cheap hobby of mine.

What were not all already ham operators?

I have been pulling my hair out troubleshooting and finally realized that my sunhams amp's are defective. Lets see how responsive rexuav is with exchanges.

Good luck hopefully they will turn them right over for you without any friction.

These the golden 3w ones? Wow. How the heck is that possible?

beanbubba · Jul 19, 2017

I received the off-brand 2W amp's today and I bet these suckers will fit in the space between the mother boards (the one and only open space on the mavic). But it might overheat making contacts with the chips on both boards??

I am not sure, but possibly over ran the receiver sensitivity with some unsanctioned testing

To be honest: I would not put these inside my mav! It would be like swallowing glass.
They will overheat and make other stuff overheat and cause motherloads of interference.

I sure hope DJI releases a Mavic2 that has just a little extra breathing room inside, slightly bigger motors, and an external southbound battery input

I know... dreaming...
