Mobile broadband antennas

Rohde&Schwarz offers broadband antennas that are designed for skywave transmission over short, medium and global distances.

The HD 420/421 mobile TFD (terminated folded dipole) antenna 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.

The antenna is configured as an inverted 'V' so that only one antenna support is required. Signals are fed in at the highest point in the middle of the antenna via a transformer. Corresponding to its geometry, the TFD antenna radiates horizontally-polarised waves and is thus suited for transmission of skywaves over any distance.

The R&S HD420/421 is said to be easily assembled and is also suitable for stationary use. Where space is limited, the length of the antenna can be reduced considerably by using two lateral 4 m masts.
