Phantom 3 standard hd on wifi icon

[Ross1137]

Hi guys, now I've searched the internet for 2 days about this with no success , but every now and then my phantom 3 standard controller will show a hd icon next to the wifi icon! Now from what I understand it's only displayed on phantoms with lightbridge technology, i have an argtek antenna system on it with a homemade windsurfer (3000 metres!)
Can someone out there please explain why I get this hd icon, I've only seen it since I put on the windsurfer.
Thanks for your help

I think that's normal, I think the icons changed slightly with newer versions of DJI Go.

But it comes and goes which I find strange.

If your phantom is working fine with no issue, don't worry about the icon. Enjoy flying!

I haven't flown a standard for quite a while, but my guess would be that HD is showing a strong enough signal to downlink at 720p, and disappears when the signal downgrades to 480p
