m8n

Hey my question today actually is not about dji. So here it is: If i have a gps unit, let say ublox Neo-M8N gps module. Is it possible to attach 2 ceramic antenna to it? Will it be any better than only using 1 antenna?

I usually peak out at 11. Just wondering if I add some shielding to the cables that will go up. Was also considering upgrading the GPS receiver to the Ublox M8N that utilizes Glonass sats.
