25-8334_Attachment_B-Tower_Site_Locations.pdf

This is an attachment document outlining tower site locations for Collier County's P25 public safety radio system maintenance and support services procurement (RFP No. 25-8334). The document specifies 15 tower sites across the county's service area, categorized as either single-site or simulcast locations, with detailed technical specifications for each site including latitude and longitude coordinates, antenna center line heights in feet, and effective radiated power measurements in decibels. The sites span geographically from Loop Road to Marco Island and include locations such as Immokalee, Naples, Corkscrew, and Krehling. Additionally, the document identifies mutual aid site locations that support specific channel configurations (8CAL90, 8TAC93, 8TAC92, and 8TAC94), with seven sites designated for mutual aid purposes across the county's public safety communications network.

The tower site inventory represents the physical infrastructure backbone of Collier County's mission-critical 800MHz radio system serving approximately 11,000 public safety and governmental users across five counties and nearly 2,300 square miles. The simulcast cluster comprises 12 primary tower sites providing redundancy and coverage reliability, supported by two distributed control points and associated network infrastructure. Antenna center line heights range from 130 feet at Marco Island to 295 feet at WAVV, with effective radiated power measurements between 53.3 and 57.6 dBm, indicating varying coverage capabilities across the service territory. This technical specification document supports the broader RFP requirements for comprehensive maintenance and support services of the existing L3-Harris radio equipment and network infrastructure, with a pre-proposal conference and site visits scheduled for November 21, 2025, and proposals due December 10, 2025.
