Lookout Pass Repeater and Site

The Lookout Pass UHF repeater is located at an elevation of 6,060 feet on the Mullan Pass/Lookout Pass Mountain ridge right on the Idaho and Montana border just north of Interstate 90. Coverage is very good in almost all directions from Washington to Missoula. The antenna is a DB Products DB-420 omni-directional 8-bay antenna at 9.5 db gain at the top of the 40 foot tower. The repeater is a Motorola MSF 5000 operating at 110 watts and has an ARR GaAsFet preamp on the receiver. This site is the furthest from Helena and MacDonald Pass and is too far to link directly, so will eventually be linked to the system using a permanent Echolink connection. The repeater operates on a frequency of 449.2 input and 444.2 output and requires a CTCSS tone of 131.8 to access. The site is difficult to get to in the winter and reliability is the goal.
