ANT - Antoine Creek Instream Array

Antoine Creek enters the Okanogan River at RKM 98.5, approximately 6 km upstream from the city of Tonasket, WA. Site ANT is located on Antoine Creek, 0.48 km upstream from the confluence with the Okanogan River. The site consists of 4 passthrough PVC antennas in series. Antenna sizes are as follows (upstream to downstream): Ant1 9 feet, ant2 7 feet, ant3 7 feet, ant4 11 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 ANT site has remote communication abilities provided by a Raven XT cellular modem. This allows access to data through HyperTerminal.
