Highly-Integrated Tower Top Assemblies Simplify Base Station Installations

Pre-assembled, highly-integrated tower top assemblies (TTAs) from RFS support multiple technologies and offer the most effective and efficient way of reducing on-site installation efforts and costs.

Engineered for Worry-Free Deployment
A pre-configured and tested RFS TTA is built with market-leading, field tested and proven wireless infrastructure solutions. It includes a multi-band antenna, all required cabling and site optimization products. The complete system is assembled by RFS technicians in a controlled environment, tested to ensure it meets all operating requirements, and then shipped to a site ready to be hoisted and installed at the top of a tower. To further streamline future technology upgrades, each system is designed to accommodate easy-to-install modules. This reduces the risk and simplifies the on-site installation process associated with adding new technology to any cell site.

Pentaband Antennas Reduce Tower Top Load

As part of a complete TTA, RFS pentaband antennas enable operators to reduce tower and wind load and eliminate the visual impact created by multiple antennas at overcrowded sites. They support up to five wireless frequencies and reduce the total number of visible antennas from two — and sometimes three or four — to just one. They also allow operators to add support for new frequency bands at the tower top without adding antennas.

Innovative Cabling Eliminates Multi-Cable Designs

All RFS antennas are supported by the innovative HYBRIFLEX™ hybrid cabling solution, which combines optical fiber and DC power for Remote Radio Heads (RRHs) in a single, highly flexible, lightweight aluminum corrugated cable. HYBRIFLEX eliminates the need for traditional, multi-cable designs and provides cabling expenditure reductions, ease-of-installation and operational efficiency.

Colocation Filters Maximize System Capacity and Performance
RFS TTAs also include colocation filters that eliminate RF interference caused by multiple antennas on a single tower. These filters maintain appropriate isolation for colocated base stations, remove unwanted carrier frequencies, and provide flexible site acquisition options for any LTE deployment.
