GPS signal booster

[syotr]

Hi. I tried to fly my phantom today with cloudy weather but could not lock more than 5 satellites.sometimes 6 but after I move it I lost 1_2 satellites.
any gps antenna for better signal or anything I can do to have better signal?

I installed the 4mm thick GPS antenna on my Dex quad. It uses the external NAZA GPS/compass module on a mast. It definitely improved reception and speed of satellite acquisition. I can lock enough satellites inside the house to fly with GPS if I wanted to.
