Baltic Networks is a good source for Ubiquiti node and accessories. They have a very nice mounting bracket for Nanostations that can be used as a mast mount or a wall mount. The ball arm allows for easy aiming It is only $6.50!!!

If you don’t want to run a wire to your computer, you can get one of these. The part on the right is the POE injector that comes with your Nanostation or Rocket M2. The part on the left is called an Airgateway. It snaps right onto the POE injector and provides WiFi connectivity so you can connect to the mesh network with any WiFi device like a laptop, smartphone or tablet! They are only $18.10 from Amazon:

PAVE PAWS (FPS-115) ballistic missile early warning radar at Beale Air Force Base in California
On October 4, 1957, the Soviet Union stunned the world with its surprise launch of Sputnik-1, a two foot diameter 180 pound man-made satellite orbiting the earth every 92 minutes.
This Soviet achievement caused the United States and Canada to build a massive military defense system which would give warning of an attack by “orbiting bombs.” ICBMs had not been invented yet.
That system, the Ballistic Missile Early Warning System, will be described in detail by a person who worked on the BMEWS project for 400 days in Northern Greenland.
Skip Aubry was first licensed as KN2LXC in 1955. In 1964, while serving in the United States Air Force, he was a certified Electronics Counter-measures instructor for *SAC EB-47 bomber flight crews.
* Strategic Air Command
In 1968 he joined RCA Service Company as a Tech Rep and was assigned to support the RCA BMEWS presence in Northern Greenland.
As an RCA Tech Rep he was initially a BMEWS radar System Engineer and later a BMEWS Computer operator. While in Greenland he was licensed by the Danish Government and was active on the ham bands for more than a year as OX5AC.
Come find out more about this fascinating fellow at our April SBARC Club meeting and about what it was like to think that during the next few seconds our lives and those of our neighbors could be turned upside down.
We hold our Santa Barbara Amateur Radio Club meetings at the Goleta Union School District, 401 N. Fairview Ave. in Goleta, right across the street from the Goleta Library. Doors open at 7:00 PM and the meeting starts at 7:30 PM.

These guidelines were prepared for the Superstition Amateur Radio Club in Mesa AZ. I hope you find them informative and useful.
The guidelines are intended to maximize mesh network success while minimizing interference. It may be appropriate to modify the guidelines as we accumulate input and experience.
WEBSITES – Use the www.aredn.org and www.bbhn.org websites to supplement these guidelines and learn more about installing and using a Broadband Hamnet mesh network
FIRMWARE – Install the most current supported (not beta test) firmware for your devices; AREDN is preferred, BBHN is compatible; use BroadbandHamnet as the SSID prefix and Callsign-DeviceAbbrev-DirectionPointedAbbrev as the Hostname, like WB9KMO-NSM2-S60; use directions like OMNI, N, S, E, W, NE, SSW, E60 (east, 60 degrees wide), 150TO210 (from 150 degrees to 210 degrees), ROTATABLE, etc.
DISTANCE BETWEEN NODES – Ensure that your node’s “DISTANCE” value is set optimally; too low will timeout before connection; too high will cause unnecessary delays; this is critical to performance.
DHCP ADDRESS RESERVATIONS – On the Port Forwarding, DHCP screen, ensure that you name your local devices and assign IP Addresses as DHCP reservations on nodes beginning with your callsign to reduce name collisions. (is. K5DLQ-RASPBX)
INTERNET OR NOT – Generally, use apps that do not require an Internet connection so they function if the Internet is down (during a disaster); optionally, connect to the Internet to allow additional functionality; you DON’T need to enable “Mesh Gateway” if you just want to use local devices that don’t require an Internet connection
2.4 GHZ OUTDOOR NODES – Only use Channel -2 with a bandwidth that stays in the band (5 or 10 MHz); limit transmitter power to the minimum required for acceptable quality; limit the antenna beam-width to the minimum required for the desired nodes and users; select antenna direction and polarity to minimize interference with unintended services and users
2.4 GHZ INDOOR NODES- Use any channel and bandwidth that is legal and minimize interference outside of your building; limit transmitter power to the minimum required for acceptable quality
2.4 GHZ ON-PROPERTY NODES – Only if necessary, use any channel bandwidth that is legal for connections on your property (indoors or outdoors) and minimize interference outside of your property; limit transmitter power to the minimum required for acceptable quality
INTERFERENCE REGULATIONS – Amateur Radio spread spectrum (SS) emissions are regulated by the FCC (Part 97). (NOTE: I have been told that AREDN/BBHN transmissions are not spread spectrum. If that is true, the following may not apply.) §97.311 SS emission types (b) A station transmitting SS emissions must not cause harmful interference to stations employing other authorized emissions, and must accept all interference caused by stations employing other authorized emissions.
INTERCONNECTING LOCAL NODES – To interconnect users on different bands and channels, connect your local nodes together; for two nodes, connect the POE ‘LAN’ ports together; for more than two nodes, connect them with a network switch that is dedicated to the mesh network (and typically not on your LAN or the Internet), like a Linksys WRT54x or a NetGear GS10x
ADDING LOCAL I/O DEVICES – To use smartphones, computers and printers on the mesh, connect a Ubiquiti AirGateway or equivalent device to the mesh network (and typically not to your LAN or the Internet); on the AirGateway Network tab, change the mode to Bridge; connect the devices to the gateway with Wi-Fi; use the channel guidelines presented above.
SUPPORT – Access the AREDN Forum on www.aredn.org to ask questions and learn about other network options and applications
Over the years, various organizations have established phonetic alphabets in order to ensure that spoken letters are properly understood. Despite the goal of universal understanding, the spoken word for each latter varies. For example:
Western Union: Adams – Boston – Chicago…
RAF: Apple – Beer – Charlie…
US Army: Able – Baker – Charlie…
ITU: Alfa – Bravo – Charlie…
NYPD: Adam – Boy – Charlie…
All of these organizations have been in existence for a long time and continue to be well-known today. In order to ensure that SBARC has the recognition that it deserves and is well-known, we have decided to adopt our very own phonetic alphabet. It will serve the primary purpose of ensuring that callsigns, abbreviations, and unusual spellings are understood, it will give SBARC the same recognition as the organizations above that have developed their own phonetic alphabets. Please use the official SBARC phonetic alphabets on QSOs, in nets, and anywhere else as appropriate.
