Toston Repeater and Site
The Toston repeater is located
on Lombard Mountain about 7 miles southeast of Toston, Montana. It is at
an elevation of 4,575 feet and on a 100 foot tower. The repeater is a UHF
Motorola MSF 5000 110-watt station with an ARR GaAsFET Preamp. The repeater
antenna is a Decibel Products DB-413 8 bay semi-directional antenna located
at the top of the tower and fed with inch and 5/8s heliax. The antennas
pattern is oriented directly into Bozeman while still providing plenty of
omnidirectional gain as well. Testing has showed that the repeater easily
covers Bozeman, Belgrade, and much of I90 towards Butte, as well as US12
and State Route 287 from Winston to Three Forks. This repeater will be permanently
linked to the MacDonald Pass Repeater.
