Do you mean something like this:

This idea actually came up as a possible idea between another ISP and me not
long ago. I can get the 5605 joule rated version (looks identical to the
one listed above) for about $100.00.

This is true on the larger more expensive APC UPSs, but the smaller 500 -
750VA models don't have this feature, do they?

Can you explain your plan on getting 1' panels passed in the 4 6 GHz

Any of the Smart-UPS units have this option. There is a little
push-button on the back that you can change the sensitivity without
having to use the software.

Which ones? I'd only use Smart-UPS and AFAIK, they all have that feature.

I HIGHLY support NOT lowering the antenna size requirement for 11Ghz, as
anything smaller than its at today, just compromises long haul backhaul

As said, this is an adjustable setting on the UPS.
What Felix is talking about is the switch from line to battery is detected
as zero voltage by the powered equipment. There is no doubt that this

However, at the time we decided against it for cost reasons. We did not need
