Badger Pass Repeater and Site

The Badger Pass site is unique in that it currently does not have commercial power. As such, we have installed a Solar Power Plant consisting of 4, One Hundred and Thirty watt Kyocera solar panels, feeding a 1235 Amp Battery Bank to power the UHF repeater and Ubiquiti Microwave. Badger Pass is an excellant location, at over 7,200 feet, it looks over the Dillon valley as well as west into Bannack and Jackson. Coverage from Idaho to the Divide/Wisdom exit on I15 has been tested, along with MT highway 41 from Dillon to I90 and including I90 coverage from Whitehall to Homestake Pass east of Butte. The UHF repeater consists of a Motorola SLR5700 repeater operating at 50 watts and a Ubiquiti Microwave radio pointed at Dillon, Montana. The antenna is a Decibel Products DB-420 fed by Inch and a Quarter Heliax at 55 feet above ground. Because of the high capacity Solar Plant, we operate this repeater on a DC only power supply drawing about 1.3 amps while in standby, the repeater, the Microwave Radio, and a computer internet switch. More information on the Digital DMR and Brandmeister Network can be found on our Digital Website at DMR Montana.
