1) Hold the working Pi near the antenna with the dongle running on another PC. If it's the same, then get/make a shielded box for the Pi, and ground.

2) If clean, then try a shielded USB cable with ferrite rings on it. Ground the Pi to a proper earth.

I'm assuming that:

1) The antenna and gain settings produce a decent reception when on a PC.
2) You've tried moving the antenna further from the equipment.
