Large Erection

Tower Technologies, LLC can handle the complete construction of a new raw land tower site or a co-location.

We carefully coordinate the efforts of site surveyors, utility locators, foundation drillers, electricians, tower crews, crane operators, excavators, landscapers, steel workers, tower manufacturers, shelter manufacturers, concrete contractors, local power and telephone companies, welders, engineering firms, building inspectors, fencing crews, roofing contractors, as well as, various material and equipment providers.

Upon completion, we provide a complete set of close out documents that include red lined drawings, site photos, a sweep test report, a ground resistivity report, any inspections required by the building permit, any electrical permits, a certificate of occupancy, a tower height verification, and a concrete strength report.

Monopole

Tower Technologies, LLC has erected dozens of monopole towers. Usually, the tower itself will be delivered by truck from the manufacturer directly to the job site. With a large crane, the tower crew off-loads the monopole, installs the climbing pegs and safety climb system, and then erects the four or five sections of the tower. If weather conditions are good the tower can be assembled in only a few hours.

Close up of cell antennas

Most recently, the antennas and lines installations we have performed have include six antennas and twelve lines of 1 5/8" coax. Usually the antenna system also includes a TMA (Tower Mounted Amplifier) with bias Ts, or a diplexer mounted either up by the antenna or near the radio equipment. Along with guyed , self-supporting, and monopole towers, we have also installed lines and antennas on a number of roof tops, water towers, a church steeple, and a silo.

Structural Upgrade

Sometimes a tower may become overloaded or incapable of handling more equipment that a cell phone carrier would like to add to it. When this happens, one solution is to upgrade the tower structurally. For example, a self-supporting tower or a monopole usually have more steel bracing bolted or welded to it. A guyed tower will typically have new heavier gauge guy wires installed.

Poured foundation of Communications Shelter

Shelter foundations can require frost walls up to four feet deep. Typically we use rebar and welded wire fabric to reinforce the strength of the concrete. Concrete break tests confirm that a minimum strength of 3000 psi have been reached after 28 days.

10’ ground rods 5/8" in diameter are driven into the ground four feet below grade. #2 solid tinned copper wire is then exothermically welded to the top of the ground rods to form a ring. From the ring, leads of #2 solid are extended up above the ground and connected to parts of the site that require grounding. We use a three point fall-of-potential method to test the ground resistivity to confirm we have 5 ohms of resistance or less.

Offloading a Shelter on site.

Shelters are delivered to cell sites by truck from the shelter manufacturer. When the shelter arrives at the site we have a large crane set up to lift the shelter off the trailer of the truck it arrived on and set in place on the shelter foundation.

Sweep testing coax with the SiteMaster

After the lines and antennas have been installed, we need to verify that the antenna system is functioning properly. This is done through a process called sweep testing. Sweep testing is a powerful tool we use to troubleshoot and pinpoint faulty communication systems. We use an Anritsu SiteMaster to test the coax, antennas, and other components in the system to make sure they meet the specifications required. The experienced technicians at Tower Technologies, LLC have conducted thousands of sweep tests.

Waveguide on tower

Tower inspections are done for a couple of reasons. One is to verify that the lines and antennas were installed properly. Another reason is to perform a structural analysis to find out if a tower can safely support the equipment that is on it or new equipment that may be added to it. Complete tower mapping may be requested to document the current antennas and equipment on the tower. We can provide a detailed tower mapping report including pictures and measurements that can be used to structurally analyze a tower.
