Almost everyone has one of these running 24/7 already. Second one with an external antenna wouldn’t make much difference.

      Ukrainian grid has been targeted by russian drone and missile strikes for years and it just keeps coming back. Longest downtime (according to a quick google search) was approximately 12 hours. Complete long term blackout in a big European city is very unlikely these days.

        Long term as "days", yes. But all of Spain had a blackout for at least 12 hours a few weeks ago. Turin, Italy, had a 10 hours blackout yesterday.
