I'm guessing that you mean a "SCADA" antenna -- it's simply any sort of antenna that's used for SCADA -- Supervisory Control & Data Acquisition, basically remote control or telemetry type stuff.

Scala *was* an antenna company, but they merged & then got absorbed years ago into what's now this:

One cool thing I remember about Scala from back in the day -- they made the primary VHF omnidirectional base antenna for the FBI. It was a design that tended to blatantly stand-out due to several loading coils, *and* it just wasn't popular with any other government or commercial users, so *if* you knew about this, it made it pretty easy to spot unmarked FBI offices back in the 1980s & 1990s until these antennas were replaced by more common-looking models.
