On Board AT&T Cell Modem Antenna Location & Upgrade

[GTGallop]

As a Ham Radio guy, I like all things radio an the onboard modem / cell phone is not excluded. I'd like to see if I can find it and disconnect the stock antenna so I can connect an upgraded antenna that would let the WiFi in the truck act more like one of those WeBoost Cell Extenders.

Does anyone know where the stock cell antenna is located?

Eh? No love for the onboard cell phone?

This should point you in the right direction. https://www.ranger5g.com/forum/threads/onboard-modem.4098/

Very interesting thread.

Looks like the guy never found out how to read the CAN Bus, though.

It would be super neat if we could flash a custom firmware and unlock the modem for future use.

Verizon would be awesome to have on these trucks.

Gracias! Now to figure out which of the two antennas is wifi and which is cell. I'm off to the races!

Bumping this thread. @GTGallop did you ever upgrade the antenna? Would love to do the same on mine.

Nope - I gave up. Still interested and probably a good time to bump it back to the top if technology / products to support this have changed.

I did change Cell Providers to First Net (serviced by ATT). Unfortunately that means that my Cell Phone now gets better coverage than the ranger I'm riding in does. Would be nice if I could upgrade the onboard modem to that enhanced plan.
