Mobile TFD Broadband Antenna

Key Facts
Picture R&S®HD420 Antenna

1.5 MHz to 30 MHz

Sky wave transmission over short, medium and global distances

The Mobile TFD (terminated folded dipole) Broadband Antenna R&S®HD420 operates as a loop antenna 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 antenna radiates horizontally polarized waves and is thus suitable for the transmission of sky waves over any distance.

Since the antenna is 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.
