Log-Periodic HF Antenna
Key facts 2 MHz to 30 MHz Transmission and reception of horizontally polarized waves over medium to long distances The compact, rotatable HF Antenna R&S®HL451 can be used for transmission and reception of horizontally polarized waves. Due to a transmission frequency range from 5 MHz to 30 MHz, the antenna is particularly suitable for communication over medium and long distances. Reception is possible from 2 MHz and thus covers all distances. The antenna has been optimized for small size. Despite the low limit of its frequency range, the R&S®HL451 is no larger than any comparable antenna covering a range from only 6.2 MHz to 30 MHz. Recommended extras Antenna Rotator R&S®RD130 Control Unit R&S®GB130
