University Mountain Repeaters and Site

The University Mountain repeater is located at our site about 3 miles East of Missoula, Montana along the South side of Interstate 90. The site sits at an elevation of 5,366 feet and has an 83 foot tower. The UHF repeater consists of a UHF Motorola MSF 5000 operating at 110 watts and has an ARR GaAsFET Preamp on the receiver. It is operating into two Celwave PD-1151 antennas at the top of the tower and fed with 7/8s heliax. These repeaters cover the Missoula valley and surrounding areas, along with providing Interstate 90 coverage from East of Drummond to West of Superior. Coverage is also provided into the Swan Valley, Hamilton, and the Flathead Valley. The UHF repeater is linked into the MacDonald Pass site via Echolink. Additionally we operate an APRS Digi-peater ("UNVMTN") at this site and it is connected to a Telewave 2.5Dbd gain antenna at the top of the tower.
