GPS scratches

Is there any problem with small scratches on the top of the GPS. I'm assuming the antenna is the large square part or is it the small circle in the middle?

 

I got two of these today and one has scratches and other less. I am replacing one that I'm having trouble with. It reads 8-9 sats and then goes to 0 and back again. It has scratches also but has also been in some crashes so may have problems because of that.

 

I usually put conformal coating on all my boards and the GPS I use clear shrink wrap. Is there any problem with that interfering with reception?

  • Did a flight with the new GPS and had great results. Also I just installed 2.0.50 and the quad really flew much smoother. Tomorrow I will see how loiter holds.
