T-Mobile Booster External Antenna

[Rjbierce]

Hey, everyone. Got a question. Has anyone tried to connect an external antenna to the T-Mobile boosters? I already have antennas from a previous setup, but I'm not sure what kind of connectors these need. I'll try and get some pictures posted. Any advice would be appreciated. Thanks.

I'm thinking this is the one i need. Might just give it a shot and see.

It is hard to tell but they do appear to be U.FL connectors.

Thanks for the feedback.

I know it's not the same connectors used for the antennas in the USB adapter for the MC7455, not sure what type those are though. I tried those to see if it would work and I need something similar, but a bit smaller.

It's probably hard to tell from the pictures, but I think the connector would need to be male with a small pin in the middle.

Then it is not a U.FL.

You might refer to this chart:

The MHF4 is another common connector type and fits the M.2 modems (i.e., Sierra Wireless EM Seriesof modems). They are a lot smaller than the U.FL which is what you have in your USB enclosure.

I found something that looks like what is on the booster.
I think it may be a MHF-SW type connector, though I can't seem to find a cable for it.
Have you seen anything like this before?

I'm thinking that the connectors are more for testing/troubleshooting purposes and not antenna connectors as I originally hoped. Connecting an external antenna to the booster may not be possible after all. I'll try pulling the board and seeing if there are any connectors on the back.
