Ubiquiti sector antennas bleed quite a lot of back radiation. The Rockets bleed an enormous amount of radiation and more is leaked through the pigtails.
SOLUTIONS:
airMAX™ is Ubiquiti’s primary platform / protocol, and is mostly on their outdoor access points and bridges
AirMax 802.11n products: AirMax MIMO 2×2 technology & dual-polarity antenna technology enable much faster data-throughput & higher bandwidth: Therefore these technologies enable high concentrations of VOIP, streaming media, IP cameras, IPTV. AirMax products have a capital M in the sku or the name (example: NanoStationM2 sku NSM2). For maximum data-throughput & highest bandwidth: Use AirMax products that are MIMO / 2×2, and if an external antenna is required, combine with a dual-polarity antenna.
Ubiquiti newest-generation of platforms:
If the tree(s) are not too thick or if your link is from a high point to a low point, 2.4GHz will probably suffice. But if 2.4GHz is over-crowded or the tree(s) are thick, 900MHz would be a better solution.
The following 900MHz options can pass through a single thick tree, or a small group of trees.
The lowest-cost option for a short link, to pass through trees, is LOCOM9
For long-distance links to pass through trees, use NanoBridge M9
The 64MB version does not work with an older version of the Open-WRT kernel: You have to download the latest kernel.
The 8MB version will work with ther older and the newer kernels.
If you use an older kernet, you will not be able to ping the router, and DHCP services will not be working.
Through the console cable, you will see errors like this:
VFS: Cannot open root device “(null)” or unknown-block(0,0)
Please append a correct “root=” boot option; here are the available partitions:
Kernel panic – not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Unlike standard WiFi protocol, Ubiquiti’s Time Division Multiple Access (TDMA) airMAX protocol allows each client to send and receive data using pre-designated time slots scheduled by an intelligent AP controller. This “time slot” method eliminates hidden node collisions and maximizes airtime efficiency. It significantly improves performance in throughput, reduces latency, and increases scalability compared to all other outdoor systems in its class.

Hello,Thank you for letting us know, we can most definitely initiate the process after you have returned, there won’t be any need for you to return the malfunctioning item.If you can give us a heads up when you’re back in town so that we may ship you a new one.-AnneOn Wed, Sep 12, 2012 at 4:32 PM, Ed Koloski wrote:Hello,
I recently placed an order, number 71699, for one antenna as well as a BNR2 magnetic mount. I have received both and verified that the antenna itself is functional, however the mount appears to have an issue.
The center conductor of the coax cable does not appear to be connected to the center pin of the antenna mount, I have verified this with an ohm meter. I have also tested the SWR of the antenna using this mount as well as another N connector mount I have on hand. When the antenna is connected to the new mount, its SWR is off the scale – when connected to my older mount, the SWR is at a reasonable 1.4.
I would like to return this antenna mount for a functional one as either the coax has a break, or it is not connected to the N connector.
One side note, the timing for this is somewhat unfortunate as I will be leaving the country on vacation on Friday 9-14-12 for just over a week. Would we be able to initiate the RMA process once I have returned?
Thank you,
Edward Koloski
