Cool video!

No offense but that kit is pricey. But, might be better for those without soldering and construction skills.

About $12 in sma connectors, round file (dremel w/round sander attachment be helpful but not required), soldering iron and little patience, you can have a much better (and looking) mod:)

Remove the old ts-9's, replace with the PCB SMA connectors ( https://amzn.to/3j6oIvK ) and very stable setup.

If I had one of these hotspots, would make a quick tutorial. Maybe that be a future project. Will be flood of them on ebay after the home schooling dies out...

I heard that those antennas on the inside are not for the us. But don't know if that is true or not.

Great idea!

When making mods like this, you should try using SMA made for PCB's. Notice the 4 (four) fingers on link below, they fit over the PCB and soldered to the ground copper foil. Center post of course is for the signal output:

Hello
Looking at AT&T plans again. So looking into doing this now. Ordered those type of fittings to solder then on the board. The pin is larger than the ts9 ports so don't fit in there.
Am I missing something?

Any luck with this? I just ordered a used one off eBay. Moments later, I saw a post on the Netgear forums, that said the internal antennas were for 1800-2700mhz. They also said the external TS-9 ports were for 700mhz bands. There is no band 13 support (right?), so I'm not sure how accurate this is. The same person also said the internal ports were uFL SMD. Can you verify this? 😁

I definitely need band 2 & 66, 1900mhz & 2100mhz, respectively, as I'll be using on Visible, hopefully.

I never did all four antennas. Just the two of them. The issue is they come loose after while. Soldier is not super strong when you are screwing wires on over and over.

I know that this thread is a bit old, but I’ve done some simple tests using the internal antenna connectors.

I wasn’t happy with the drilling holes in the front strategy, so I modified the board a bit and soldered on a couple of U.FL connectors alongside the proprietary antenna connectors. Don’t worry, I’m a professional!

I’m not entirely convinced that the connector labeled “3” is for the LTE antenna, because it doesn’t have the same components around it as 1, 2, and 4, but I routed it and “4” out of the case using U.FL to SMA pigtails. I had to modify some of the internal plastic case to get it to fit, and just made small notches just big enough to fit the pigtail cables through.

It seems that there are seven internal antennas, so I’m not sure which is which.

Anyway, after I had the cables routed out, I hooked it up to my 4x4 panel. My signal, just the simple one in the web GUI, improved by 15dBm. I’m pretty rural and far from the tower, but my download speeds went from about 30Mbps to 65Mbps.

I tried it with and without the internal antennas plugged in and saw no difference in speeds at all. Removing the antenna from connector 2 dropped my speed from 65Mbps to around 40Mbps, and removing the last connector from antenna 1 dropped it back down to 30Mbps.

In the web GUI, only antenna 1 made any difference in the displayed signal levels, but I realize that that doesn’t show the full picture.

In summary, routing the internal antenna jacks to the outside and connecting them to an external antenna resulted in no improvement - at least for the bands that I’m using here. I’m quite sure that the method that I used was better than the eBay kits, as I examined one of those types of connectors that they use and don’t think that they would be grounded properly. The U.FL connectors that I installed resulted in a very solid connection, but no improvement.
This deterred me from trying this, but reading it again, I may have it wrong. Are you saying that you hooked two antennas up to the outside ports and then two to the inside?

From what I understand using the outside antenna ports completely disables the internal ones. If that's the case, you'd have to use all 4 of the internal ports. Is it possible you can try this and report back?
