After two nights of record windstorms, today (Sunday) was devoted to an impromptu “tower tour,” driving around our service area and checking for visual confirmation of proper aim on the majority of our towers.
The Easy Street input feed dish had been blown clockwise about 70°. (The Easy Street neighborhood itself was pretty slammed, with roads strewn with wash silt and downed trees; our host’s flagpole was actually bent in half by the winds!) Without a roof man, given that the dish was far above my reach, I attempted a rough re-aim job by “pokin’ a stick at it” (our 16′ telescoping pole) from a ladder, with surprisingly satisfactory results.
The output feed from the NOC to 251st Avenue had also been blown off kilter, and was re-aimed in the same manner. The mast has gone a bit wobbly over time, which will be addressed when we can schedule Dave, our roof man, to fine tune and lock in all of today’s crude readjustments.
One thing these storms made quite apparent is a need for more UPS power capability than we currently enjoy. Although the NOC, Constellation Tower, and our Wickenburg gateway are hardened by indoor UPS systems that provide them about 90 minutes of emergency power, most of our towers have no UPS. During the last two nights of power outages in central Morristown and Castle Hot Springs, all our Morristown tower subscribers were taken offline immediately because no power was available to our windmill tower—even though the NOC continued operating (and serving 251st Avenue, which suffered no extended power outage either night).
As funding allows, we plan to begin introducing indoor UPS systems at host-based towers, which is technically simple—weatherproof UPS units for the standalone towers (Morristown, Mockingbird, and Rio Vista) are expected to be more problematic, but a search for suitable equipment is on our immediate agenda.
In addition, it’s clear that the sheer amount of equipment installed at the NOC and the gateway locations deserves beefier UPS units that can provide more than 90 minutes of outage protection, since when these locations go dark, many or all towers lose service.
There’s nothing like weather problems to trigger a Red Queen Marathon: a situation where you must run as fast as you can just to stay in the same place. We’re going to be running one of our own over the next few months, to better prepare ourselves for future monsoon devilry.
(And the weatherman says there is 45% chance of a third record windstorm tonight.) 😭
