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.
