Horry County 911 is looking to improve dead zones of coverage in the county. At Tuesday’s Public Safety Commission meeting, Horry County 911 proposed a $3.2 million request for equipment that would improve two radio towers. Horry County 911 has contracted with a company to help find towers that would improve coverage. She said the costs would at least double if towers had to be built and land needed to be purchased. The towers are not currently funded or planned. The request has not gone before the county council.
