Yup, that is the orientation I used. I got more than 6200 feet (1.18 miles) out of the stock antennas of the ST16 of the Typhoon H Pro.I have been playing with different antenna orientation over the last few flights and I have found for me at least that if I have them pointing at 90 degrees up I get the most stable connection with no losses at all,tried a few flights and stable as a rock then changed orientation and video loss occured as before.
I was actually shocked how well the antennas work, given the limited range of 2.4GHz and 5.8GHz WiFi.
