it's a 1" OD (2,54mm exterior) conduit for electric cables...PVC...(Really THIN WALL) any PIPE would DO The LESS plastic the BETTER
-
-
GND would have continuity to any of those IC EMI SHIELDS (aluminum tin covering circuits) that's COAXIAL SHIELD (MESH) GND...just to be sure...
-
Yellow ring is SHIELD (GND) (careful with those hairs, make a ring with solder) RED line is inner WIRE...50ohms feed point https://www.wifi-antennas.com/uploads/monthly_2020_09/5f714c7f94137_frontdesoldered.jpg.c2757e4d0fc1d166241bf1cbe9d605d3.jpg.7e186604399d80e2a8f10e2d24415cec.jpg

Electromagnetic Fields at HIGH Frecuencies...behave like witchcraft ...(before simulations was hard to figure it out...and still is)
-
It's a PIFA antenna (low gain)...Check continuity ...but i think cable (50ohms shorter you can) goes like this Try with a DIPOLE
-
DISTANCE and AREA/SHAPE (curved angled) is IMPORTANT ...fiddle with it use a fast and sensible indicator of level quality
-
Transformed from dwg , 9mm to reflector , 1.5mm FR4. ant24-1800.cst
-
I start up with PEC and NO loss materials...then ...when you get close to your goal , you could switch'em to REAL WORLD materials... PS: The ENCLOSURE has a MAIN ROLE in FR , and losses...imho
-
if you don't get closser to -60dbm or even under -60... AND link QUALITY (PACKETS) OVER or CLOSE to 70% you won't have SPEED or stability If you can , try a reflector (ANY METAL) behind your antenna and the signal direction...
