ALLISS HRS type antenna
The HRS type antenna is one of the most common types of curtain array.
The name comes from the above CCIR nomenclature: it consists of an array of Horizontal dipoles
with a Reflector behind them, and the beam is Steerable.
These antennas are also known as "HRRS" (for a Reversible Reflector), but the extra R is seldom used.
