I just purchased and installed that kit exactly for my new Rockethub ZTE MF275.
I checked out the MiMo antennas listed in Amazon and the small indoor/outdoor ones seem to be identical although the listing mentions specific Hubs targeted for their use. The antenna listed for the MF275R is this one:
It appears to have a double ended pigtail connector and comes bundled with two low-rent 30' cables which I would probably want to replace with heavier low loss cables.
I just have to consider whether the small boost in performance would be worth the $135 price tag
The cables are something I would definitely consider upgrading (the end at the hub already pulled out once, while trying to screw it on)
I extended mine with an additional 30 ft of cable, and mounted it on a mast that was already on my roof. (about 30ft off the ground)
Before I installed the external MIMO antenna, I was consistently getting 5-8Mbps down, and 1-2Mbps up, with the standard antenna's and sitting in a window facing the tower)
With the new antenna, my speeds are in the 20Mbps down, and 5Mbps up. The fastest has been 27.63Mbps down, 6.73Mbps up (speedof.me & speedtest.net)
My signal strength did not seem to improve, but the speeds are well worth the investment in my installation.
approx 6Km from tower
Signal Strength -113 dBm
It is good to see someone beating the bushes on the antenna front. I too picked up the identical antenna kit from Amazon, but have not gotten around to installing it yet. I think I'll have to hire someone to do the work since I am not as agile on the roof and on a ladder as I used to be. I'll keep in touch and report on how thing go when I decide to go ahead with the work.
Weather permitting, I'm going to install mine (275 + Amazon kit) this weekend. Any idea which of the 2 cables on the antenna are H vs V? Or just keep trying?.....
When I installed mine, I didn't worry about H or V. I figured that if the first connection order didn't work, flipping the two cables at the ZTE would fix it. I either got lucky all the time, or it didn't matter.
I started in the house with connecting the hub to the cables so that when I was on the roof, I could use a smartphone to test signal strength and speed before tightening everything down. I also used this site (http://www.ertyu.org/steven_nikkel/cancellsites.html) to help me aim the panel antenna in the general direction of the closest Rogers tower.
Luckily I have an almost ideal roof setup, so installation of this antenna, and removing all the old gear was relatively easy.
I did, however, have to pull power, and the battery to reset the ZTE MF275 at one point, as it had a wireless signal, but no internet access. That seemed to correct the communications issue.
Hope that helps...
