HomeMy WebLinkAbout01-09 Analysis of Communication Towers in the Vicinity19700 Janelia Farms Blvd r Ashburn, VA 20147 703-726-5500 CO MSEA R CH Analysis of Communication Towers in the Vicinity of the Proposed AT&T Corporation Microwave Tower in Winchester, Virginia Comsearch was contracted by AT&T Corporation to identify all commercial communication facilities within a 1.0 mile search radius of their proposed 120' height telecommunications tower to be located at an existing AT&T facility on Route 11, Martinsburg Pike, in Winchester, Virginia. The purpose of this study is to provide the analysis required by the local Zoning Ordinances to obtain a Conditional Use Permit for the proposed telecommunication tower. Comsearch performed a database search from multiple sources including the Federal Communication Commission (FCC) Universal Licensing System (ULS) and Antenna Structure Registration (ASR), a database of the top ten tower owners in the United States, and the Comsearch databases of all microwave and land mobile radio (LMR) commercial telecommunications systems licensed for operation in the United States. The database search determined that there were 4 commercial communication facilities registered within a 1.0 mile radius of the proposed AT&T tower. Table 1 identifies the communication facilities and lists their pertinent parameters including service, frequency band, FCC Call Sign, latitude and longitude, antenna height and licensee. Figure 1 shows the location of these communication facilities with respect to the proposed AT&T tower.

The on-site evaluation also focused on the area within a 1.0 mile search radius of the proposed AT&T facility. The results of the on-site physical visit are contained in Figures 2 — 5 for the database identified facilities. Figures 6 and 7 provide documentation for two additional facilities determined during the on-site visit and Figure 8 indicates the location of these additional communication facilities with respect to the proposed AT&T tower.. Notes are provided with each figure identifying the type of tower and a determination concerning the viability of the existing facility to support the proposed AT&T communication requirements. This determination is based on a number of criteria including 1) the ability of the tower to adequately support the proposed 6' microwave antenna, 2) the sufficient height of the existing tower to support the planned AT&T microwave link, and 3) proximity to the AT&T facility where the required communication must terminate. The results of this analysis determined that there are no existing commercial communications facilities present within a 1.0 mile radius of the proposed AT&T 120' height tower that will support the requirements of AT&T. The proposed AT&T tower is required to support a highly reliable point-to-point microwave path between the AT&T facility and a location on Mount Weather, which is in excess of 16 miles away in a direction of approximately 132 degrees from true north. The proposed tower will be required to support at minimum a 6' solid parabolic antenna. None of the identified existing communication facilities will meet the stringent requirements of AT&T.
