So these same antennas are being used in different markets? 

 

How many Band 41 carriers are they capable of? 

 

4x 2.5 rf ports = 3 carriers max unless they they have a RF Combiner for 2.6 then they can do 6 carriers as per a typical 8T8R setup by combining the 8x 2.5 jumpers from RRU to a combiner that outputs 4. A combiner does have some drawbacks in terms of signal loss though.

I could see these used in some GMO conversions as well, especially lattice/truss sites. Wood utility poles seem to be able to handle the full weight of a regular 800 1900 2500 LTE setup for at least two sectors based on observations (at least so far).

Gmo conversions, yes please!

Has this actually happened anywhere?

 
There are recent permits in Ericsson land.
 

They relocate the 800 RRU to a ground mount setup.

 
Sometimes.

Basically yes due to the fact a 20 mhz TDD-LTE carrier in Sprints configuration will top out at 80-90 mbps whereas Sprints 5x5 mhz FDD-LTE carrier tops out at ~37 mbps in the best of conditions. 

please correct me if im wrong. 8t8r is basically 8x8 mimo but no device can take advantage of that high order at the moment. so basically it splits it the antennas in half for 2 4x4 or 4x2?

Yes. They're running it in 4x2 MIMO configuration.

That's pretty cool how that works. so its like having six 2.5 connections on a tower instead of 3

I noticed a tower being upgraded near me and I would assume it is for B41.  The tower currently has B25/26 on it.  However, I am not 100% sure this is a Clearwire/Sprint upgrade.  Based on this forum, the B41 antennas are supposed to be smaller than the Sprint B25/26 antenna, however, from the link below the Clearwire B41 antenna are a little longer.  The circles in red are the new antenna, and the circle in green are the Sprint B25/26 antenna.  Are the one's in red Clearwire B41, or are they for another carrier?

The antenna on the far right looks like it has a Nokia RRU right behind it, judging by that I'd say that is a Sprint B41 install.

Those appear to be 8t8r antennas, not Clearwire.
