How do I order the high gain antennas? I didn’t get them with my initial purchase and I’m regretting it. I’m using the flightbox from FL 300 to 400 and the reception is pretty weak. I don’t see the high gain antennas available anywhere in the store.
Thank you

Don’t know if you found them somewhere else by now, but if not, I found this source:

Thanks, Steve sent me a link and I ordered them. They made a huge difference! Everything works perfectly now!

Great! I have been having trouble getting mine to work with the original antennas too.
Did you mount the high gains to the box, or remotely?

I put them on the box. I had to take it apart to install the “ground plane” (the foil-like tape), but that was no big deal.

I already installed the foil tape ground plane, and you’re right, it wasn’t a big deal, but it wasn’t enough to make the standard antennas work for me. Your experience gives me hope that the high gain ones will be the step that gets things working properly. If not I guess the next step will be to get some SMA extension cables for remote mounting the antennas.

For reference, here’s the link to order high gain antennas:
