United States Tower Services, Ltd.
Major References Summary

United States Tower Services, Ltd. (USTS) , established in 1971, is a privately owned small business founded in Montgomery County, Maryland. The company’s business base covers the sale, installation, construction, maintenance, service and support of communications towers and related facilities. Services range from specific tower related requirements to full turn key systems including heavy broadcast, microwave, commercial two way and wireless structures used by commercial TV and radio (FM/AM) broadcasters, government (Federal, State & Local) and commercial two-way radio users and the rapidly growing wireless telecommunications industry. In 1986, USTS relocated and currently operates from its headquarters located in Frederick, Maryland. At present USTS employes over 40 people. Today and over its lengthy business history, USTS has performed work for many U. S. Federal Government departments and agencies. At present USTS is under contract for inspections, repair and maintenance services nationally to both the Department of Transportation (FAA) and the Federal Emergency Management Agency (FEMA). USTS is a preferred third party organization by Andrew Corporation as a qualified HF antenna erection contractor for all of Andrew/Granger HF antenna products. In addition, USTS is a factory certified organization for the installation of transmission lines, waveguide and connectors by both Andrew and Cellwave (Radio Frequency Systems). It is worthwhile to mention, that over the entire business history of USTS, this organization has never defaulted on any of its awarded contracts. USTS enjoys the reputation of stepping in at the request of an end user or competing tower contractor, to complete a project when a competing tower company has failed to live up to contractual requirements in work awarded to them.

Competitors often sub-contract to USTS if the difficulty of work is beyond their capabilities. USTS is an early supporting member of the National Association of Tower Erector (NATE). NATE is a non-profit trade association, which provides members with uniform safety standards, improved communications, and a unified voice to help shape the future of the tower industry. Employees of USTS have also served as national office holders supporting NATE and USTS has been instrumental in development of safety standards and securing their adoption by both industry and OSHA.

These projects reflect our experience in the installation of antenna and tower systems in high-power RF environments. USTS believes these completed projects demonstrate the ability USTS has to meet a high level of effort required by our customers. Most of the projects listed below exceeded $100,000 and several were in the $500,000 to $900,000 range.

	.Lajes Field, U.S. Forces Azores Command, Portuguese Azores:
1) This project involved the construction and installation of four large HF Radio multiple tower arrays. Work included the trenching and the installation of new RF transmission lines as well as antenna site acceptance testing. All work was performed in an active RF environment, as this site is an active USAF transmitter facility. USTS had the obligation to work in cooperation with the USAF operations people and work within the dynamic operations schedule mandated by the USAF. In this project, USTS picked up and completed the work after the original contractor defaulted on the installation contract. This project was a difficult to severe logistical mission. All installation and construction materials arrived and departed by air transports.

2) Multiple in country projects were performed at various foreign locations for a U S Federal Department. These project involved the installation of various telecommunications equipment across various sites within country. From the project start time, after the original site visits and the work officially began, the first proposed installation plan was taken off the table and second and third alternate proposed installation plans had to be invoked. USTS had completed these site visits and developed alternative installation plans in advance. When USTS mobilized to the sites to start the work, we had on hand enough material to allow changes on how a site was installed. This project was also a very difficult to severe logistical mission. Additional work for USTS is currently under review for scheduling.

3) This project involved the removal and replacement of a 16,000-pound commercial TV broadcast antenna. In addition, the 9- inch rigid transmission line required on site rework. USTS modified and prefabricated a new custom 9- inch rigid transmission line section requiring the installation of field flanges. In addition, USTS service personnel used a network analyzer to complete a sweep test of the antenna and RF transmission line and tuned the installed antenna with the 9- inch feed line. The coordination of the work in minimizing this station’s off-air time was critical. This project required work in a heavy RF energy environment created by co-located commercial TV and radio antennas. The site was also in close proximity to surrounding residential property, thus creating the potential for extensive property and personnel damage if it had not been properly planned and handled.

4) This project involved the construction and installation of six new multiple tower HF antennas while working under difficult local site and logistical conditions. This project ran the course of five months. In addition to the work, moderate to difficult logistical problems presented themselves. The overall time span involved working through some harsh local climate conditions as well. Work included the trenching and the installation of new RF transmission lines as well as antenna site acceptance testing. This job was performed in an active RF energy environment, as this site is an active USAF transmitter facility. USTS had the obligation to work in cooperation with the USAF operations personnel and work within the dynamic operations schedule mandated by the USAF.

	Offutt AFB, Omaha NE:
5) The demolition of five existing multiple tower HF transmit and receive antennas combined with the on site construction and installation of seven new multiple tower replacement antennas built on two new and five existing antenna pad sites. This project ran the course of almost six months. The installations were at two work locations one being remote. In addition to the work, minor to moderate logistical problems surfaced. The overall time span involved working through a variety of local adverse climate conditions as well. Work included the trenching and the installation of new RF transmission lines as well as antenna site acceptance testing. This job was performed in an active RF energy environment, as this site is an active USAF transmitter facility. USTS had the obligation to work in cooperation with the USAF operations personnel and work within the dynamic operations schedule mandated by the USAF.

6) TV Channel 66 PAXN Broadcasting. This project involved the dismantling and removal of a Pirod 54 guyed 350- foot tower with an 80- foot combination TV & FM broadcast antenna mounted on the top. This project was performed and completed in a heavy RF energy environment created by co- located commercial broadcast TV and radio antennas, as well as it being in a heavy urban environment and in very close proximity to other large towers and surrounding residential property. If not performed with a well thought out and valid demolition plan of action, there was potential for extensive property damage and personnel damage.

7) Construction of a new Pirod 36 guyed 350-foot tower. This tower was co-located with the stations existing Rohn 55 350- foot guyed FM broadcast tower. The new construction proceeded without affecting the daily broadcast schedule (24 by 7) of not only the broadcast station, but several users that had antennas co-located on the existing tower as well. Upon completion and commissioning of the new 350-foot guyed tower, the previously existing co-located tower was dismantled and removed without interrupting the users.

	Montgomery County MD, WGMS/WTEM, Bonneville Broadcasting:
8) Demolition of three existing Pirod 400- foot guyed towers on one site followed by the construction of four new Pirod 400- foot guyed towers on a new replacement AM transmitter site built on raw land. The demolition of the existing towers was complicated by the recent build out and development of an individual housing subdivision.
