R&S®HD420 Antenna
Mobile TFD Broadband Antenna
Key Facts
1.5 MHz to 30 MHz
Sky wave transmission over short, medium and global distances
The Mobile TFD (terminated folded dipole) Broadband Antennas R&S HD420 and R&S HD421 operate as loop antennas on which travelling waves are generated by means of a termination. A tuning unit is not required to attain the specified VSWR.
Signals are fed in via a transformer at the highest point in the middle of the antenna. Corresponding to its geometry, the TFD antennas radiate horizontally polarized waves and are thus suitable for the transmission of sky waves over any distance.
Since the antennas are configured as an inverted V, only one antenna support is needed. Where space is limited, the length of the antenna can be considerably reduced through the use of two lateral 4 m masts.
