Narrative:

The frequency for feeder (AR4); failed. I was working AR1; the adjacent final sector; and needed to change radar sites and expand my range to 'take' AR4 because their frequency was unusable. After 10-12 minutes of chaos; the transition was accomplished; but at least 7 airplanes were 'NORDO' because they were on 124.05 when it failed. It turns out that tech ops took 124.05 off the air without coordinating with the correct area (la arrivals); and were dismissive of our concerns when they were first notified. There was an obvious mistake; this has been at least the third incident in the last 6 months where tech ops made a mistake and there is no accountability. There needs to be more accountability on the part of tech ops.
