Extending wifi range

I am using an external antenna with my particle photon. The photon is within an enclosure that I have drilled through and attached an antenna to.

Antenna is like this one: https://www.amazon.com/HUACAM-5-8GHz-Dual-Band-Wireless-Network-Antenna/dp/B06WD7FZV4/ref=sr_1_12?s=electronics&ie=UTF8&qid=1532435710&sr=1-12&keywords=u.fl+antenna

The whole thing is kinda a box in a box, the photon is in an enclosure which is then within a machine. I am looking to mount the antenna to the outside of the machine. Would I just be able to take an SMA cable, run it from the photon enclosure, and then to the exterior of the machine to then attach the end of the antenna to?

Yes, It should be that easy. I just took a quick look on Amazon and didn’t realize that the SMA extension cables come in 2 flavors; normal and “reverse polarity”. Make sure the cable you buy has the correct polarity on both ends. In this link, you can see the multiple variations of the cable and see which side of the cable has the center pin: https://www.amazon.com/Padarsey-Antenna-Extension-RP-SMA-Adapter/dp/B07DLSQQFW/ref=sr_1_2_sspa?ie=UTF8&qid=1532439788&sr=8-2-spons&keywords=sma+extension+cable&psc=1.

Thanks, I figured it would work out fine but I was looking for a second opinion. I also didn’t know about the difference between Reverse Polarity and Regular, thank for point that out.
