Blue Mountain Site
The Blue Mountain repeater site is about halfway between Golden, CO and Boulder, CO, near the intersection of Foothills Parkway and Highway 72, at 8100 ft. elevation. We’re in the process of rebuilding the site, following a lightning strike which did a lot of damage. Currently, we’re using a temporary antenna which is lower on the tower than we’d like it to be, but we still get pretty good coverage, with good signal reports NE to Eaton, CO. We don’t, at the moment, have a good idea on coverage East and SE, but we are reaching Castle Rock for sure.
Next on our list of repairs is to replace the cable harness for our main antenna, at which point we should be back to full transmit coverage. After that, it’ll be just housekeeping chores and minor fixups.
Here are some photos from our Blue Mountain repair work.
