ALLISS

There are some factors that separate true ALLISS technology from 'run-of-the-mill' rotatable HRS Type antennas.

[citation needed] Technically only solid radiators distinguish true ALLISS systems from all other rotatable HRS type antennas.

Only about 12% (estimate) of all HRS antennas in use globally are rotatable, and of these only 28 of the ALLISS systems have solid radiators.

ALLISS is only used by well funded broadcasting and telecommunications operations that intend to use the modules over their design lifespan of 50–60 years.

This flexibility can allow a broadcaster to redirect the entire shortwave transmission network to a strategically important target area in as little as 15 minutes.

Higher RFI & EMF (electromagnetic) compatibility vs traditional relay stations Each ALLISS module is fully automated, so there is no need for technical staff.

With conventionally designed HRS type antennas shortwave relay stations and their obligatory transmitter hall, switch matrix, coaxial or open feeder line systems and multiple antennas (~90% of shortwave relay stations are built this way) much larger staffs are required.
