Side-Tank Mount Antenna System Uninvasively Advances AT&T’s 4G Capacity Range
In progressively addressing the Long Term Evolution (LTE) of the revolutionary smartphone industry, the nation’s leading wireless carriers are seeking sophisticated antenna mounting solutions on top of strategically located water tower tanks to optimize the increased signal positioning frequency range and speed capacity required for 4G network coverage. As a result of increased competition, the real estate on top water tower tanks and handrails has risen to a congestive premium to accommodate the myriad of carriers’ next generation 4G network speed capacity antenna signal range requirements.
At the forefront of the wireless technology boom, the nation’s second largest wireless carrier AT&T recently sought out an advanced antenna installation solution to replace and expand their 4G network service range for their Los Angeles Market District 3 at the Irvine Ranch Water District. The IRWD’s 1 million gallon water tank towers 25 feet high and provides potable drinking water services to a region encompassing nearly 181 square miles extending from the Pacific Coast to the foothills. The tank features no external tank-top flange to attach antennas to; thus ruling out traditional tank-top mounting so a side-tank mounting solution was required for the installation.
AT&T’s existing antennas were mounted using epoxy bond on the sides of the water tower tank and were loose due to extensive tank movement and a permanent solution was needed to replace them and accommodate their expanded range of 4G antennas. Because of the unreliability of epoxy mounting, the IRWD had mandated an alternative mounting solution also ruling out time consuming Capacitor Discharge (CD) welding and spot welding; both of which would require tank shut down for draining and also presented potential EPA issues involving maintaining the integrity of the tank’s membrane seals.
AT&T’s LA Market District Field Operations Department enlisted their RF contractor Diversified Communications Services, Inc. to source out a permanent, modified turnkey mounting solution to the problem. The goal was to meet IRWD’s installation mandates while also expanding their 4G network frequency range from 700 MG to 2 GB by utilizing eight foot antennas vs. the existing four foot antennas.
Diversified’s VP/Founder Steve Hurley immediately contacted Metal & Cable Corp., Inc. who had developed a patented non-invasive, high-capacity magnetic solution called the Magnemount Antenna Mounting System. The system is engineered with a series of permanent magnets that combine with an independently suspended mounting system to provide a non-invasive solution to adhere to the steel surfaces with varying curvatures of water towers−including side sectors.
Available in five modifiable designs, Metal & Cable Corp. leveraged its newest model; the Magnemount Side-Tank Mount (Model-STM) design for the AT&T / IRWD installation.

Oceus Networks Demonstrates Proven Mobile 4G LTE Network at Army’s NIE 12.1 Evaluation to Support US DoD’s Move to Tactical Advanced Cellular Communications
At the Army’s recent Network Integration Exercise (NIE) 12.1, Oceus Networks successfully demonstrated the capabilities of its market leading Xiphos, a family of mobile 4G LTE tactical cellular communications networks.
“Xiphos networks provide high capacity secure wireless broadband to the warfighter at the edge,” said Douglas C. Smith, President and CEO, Oceus Networks. “Oceus’ mobile ruggedized networks can be installed in tactical warfighter vehicles, placed aboard ships, mounted on UAV’s and other aerial platforms, and can be soldier back-packed into austere environments – wherever robust high-speed voice, video and data communications capabilities are needed.”
Held at White Sands Missile Range, New Mexico, a company of soldiers belonging to the 2nd Brigade Combat Team, 1st Armored Division leveraged the Oceus 4G LTE commercial-of-the shelf (COTS) networks to use smart phone and tablet applications for real-time streaming media, voice over internet protocol, position location indicator (PLI),
email, and instant messaging to gain improved situational awareness capabilities.
Specifically, as an industry NIE 12.1 SUE (System Under Evaluation), Oceus integrated its networks with existing army programs of record including WIN-T, NETT Warrior, JTRS GMR and the WNW waveform. The Oceus 4G LTE Xiphos network was also seamlessly integrated into its 3G QuicLINK network, advancing Oceus integration efforts from the previous NIE 11.2.
“The NIE exercise is an excellent forum for the military to evaluate the latest commercially available solutions, and test the ability of effective integration of existing Army networking equipment with emerging industry innovations,” Smith said. “Leveraging proven COTS products, such as Xiphos, speeds up the military’s ability to use communications we take for granted in our personal lives, providing soldiers greater capabilities sooner but also at a lower cost to the taxpayer. The government is basically capitalizing on R&D investments of commercial companies.”
