FOS - Foster Dam Weir

The Foster Dam Weir antenna is located in spillway #4 at Foster Dam on the South Santiam River just upstream from the town of Sweet Home, Oregon. The site consists of two ferrite shielded flat plate antennas. Each antenna housing measures 11-feet by 42-inches. One antenna is mounted on each side of the weir opening. Two IS1001-ACN transceivers are mounted on the rear of the weir and have a 6-foot antenna lead. CAN-Bus (+power) cable connects the ACNs to one another and to the IS1001 MTS-MC. Site was removed in January 2018
