Local Tower Upgrades (Verizon)

an amplifier? a lot of the ones I've seen for LTE are $$$$

Yep. $250 for the one that @tgoodwin is using with his grid antenna.

ouch

I've been watching eBay for another amp. They pop up from time to time. I just missed a new in box one for $179. Made a low ball offer and it sold the next day at listing price. I was thinking it was someone from here

do these amplifiers work in both directions or just in receive ? I can't imagine they would amplify on transmit as UE limits in LTE are already +23dbm which the UE can easily do.

The spec sheet says it is bi-directional

You saw much better upload speeds with the amp than without, didn't you?

Another amp?! Is that secondary antenna getting jealous of the one that the primary has?

huh, I wonder if that just takes cable losses into effect and transmits at the max 23dbm.

I wonder if you could just run all your cabling through this thing and then split it back to the modem, or if that would mess up the spatial multiplexing cause then it would be effectively the same signal?

Nope, doesn't work that way. You'd need one for each antenna.

Yeah, was just thinking out loud here, but most spatial multiplexing processing is done digitally. That being said orthogonal signal polarizations (Vertical and Horizontal, or +/- 45 degrees) probably help reduce the digital processing with all the overhead of spatial multiplexing.
