Transmission and reception of horizontally polarized waves over medium to long distances

The compact, rotatable HF Antenna R&S®HL471 can be used for transmission and reception of horizontally polarized waves.


Due to a transmission frequency range from 7 MHz to 30 MHz, the antenna is particularly suitable for communication over long distances. Reception is possible from 5 MHz so that all distances can be covered.


The antenna has been optimized for small dimensions, low weight and little maintenance.
