OMK - Omak Creek Instream Array

Omak Creek enters the Okanogan River at RKM 51.5, approximately 1 km upstream from the city of Omak, WA. The OMK site is located on Omak Creek, 0.24 km from the confluence with the Okanogan River. The setup consists of 6 pass-over PVC antennas, three upstream (ant1 5 feet, ant2 15 feet, ant3 5 feet) and three downstream (ant4 12 feet, ant5 10 feet, ant6 15 feet). The site is on grid power. Two banks of 12volt batteries in series create 24volts to run the MUX unit. The batteries are connected to a timer switcher that will switch battery banks every four hours. The battery bank not running the MUX unit is then charged to capacity using a three-stage battery charger. The OMK site has remote communication abilities provided by a Raven X cellular modem. This allows access to data through Hyper Terminal.
