Today we show you how to carefully remove the LT500's Cellular antenna connectors. They are U.FL (IPEX1) antenna connectors.
NOTE: There are special tools to do this, specifically made for these connectors. This video is for the everyday person who does not have access to these tools that can be hard to find and relatively expensive for what they are and how little they may be used. The proper tools are generally the best way to do this, but this video shows how to safely do the job without the specialty tooling.
You really need to be careful when removing or replacing antenna connectors so that you do not accidentally damage or pull the PCB connector off of the router board. The proper tool for this job would be fully made of plastic, as to not scratch the PCB and its parts and traces. We are demonstrating with common household tools to show it can be done without special tools and without damage; make note of the twisting action, not a push or pull.
Once removed you are ready to remove the antennas that come stock with the LT500, or leave them in place and tape the cables off to the case, so that you can then place your new antenna connectors in the case and onto the cellular connectors on the router board.
NOTICE: Always be careful when manipulating antenna connectors of any kind, they are small and can be damaged. The Wireless Haven is not responsible for any damage to your equipment from following any of our tutorials. We create these tutorials in our controlled environment and after making our own mistakes. We have no control over your actions and outcome. Please be careful and carry out these changes at your own discretion and risk.
The router in the video is a Cudy LT500 Router with Quectel EC25AFX embedded. The connectors here are for the Cellular antennas for the modem.

Thanks. I broken 3 of them before
Nice! The most scary part of building a 5g router are the pigtails. Those things weren't made for my fat fingers. Would be great if there was some tool for pressing them in.
Hello Paul,
There are tools out there specifically for this.
We don't use them ourselves as we like to show the everyday person how it can be done with simple household tools, or without tools at all.
Have you seen our video for installing MHF4 connectors? We only use a simple wooden dowel for most installations like that, if we don't use our fingernail.
@@wirelesshaven I'm curious about these specialized tools. Perhaps you could go into some detail in another video and compare how we can achieve the same results without spending big bucks on wacky single purpose tools.
I've used an unsharpened, unused pencil, using the eraser side to press carefully on the connector until it clicks in.
You want to make sure the eraser is unused, as you don't want pencils lead (graphite) contaminating and shorting-out your modem.
I suggest unsharpened as you don't want to poke yourself.
Can I just solder a new cable with the connector into the older antenna cable? Would it affect the signal?
You could yes, it depends on how good the solder job is.
Should probably use a plastic spudger, instead. Less chance of scratching into the PCB traces.
True! But the video is intended for the majority of diy home enthusiasts; who don't typically have much but screw drivers laying about. We should probably note that in the vid description. Thanks!
Bro what to do if the board side covered pins shell got broke
Time for solder repair job.
no
like my move so i do it right!
