Re: Next Gateway XB8 - Technicolor CGM4981COM Wi-Fi 6E

I only worked in Wireless for a decade and a half

You can see the coax plugged into the main board I circled them in RED.

Yes, and for the XB7, at the other end of those wires you can clearly see the small, black, rectangular antennas.

Well they look like the Connections to the Panel Antenna's (PCB) I see at least 5 coax/wires)

IDK, they don't look like they interconnect anything, but just appear to end at a piece of tape.

OK, looks like you're correct. I checked with an industry source and he said that those orange things are indeed antennas (example pictured above) and what we're seeing are just the orange pieces of tape that hold those antennas in place.

I guess besides the PCB antennas, there are some additional ones that are placed above them.

Is that electrical tape holding the antenna wires to the case? The most advanced my @$$

Not sure what those different color wires are, but similar ones were shown inside the XB7 gateway also: »Re: [Equip] New XB7? Technicolor CGM4331COM - Wireless AX(Wi-Fi 6)

The FCC Test Report on it indicates most of the antennas are "PCB" (Printed Circuit Board) ones: »fcc.report/FCC-ID/G95498 ··· 2976.pdf

[Or maybe these latest Xfinity Advanced Gateways are equipped with an anti-tamper or self-destruct mechanism to avoid competitors from copying their design. In that case, to "defuse" it, do you cut the red or the blue wire first? ]
