Televes MRD 5050
Optional - Dynamic Margin Rising
Impulsive noise does not last long and is characterised by a fast risetime.
It can appear both in the UHF and in the VHF band.
Mans industrial activity pollutes the RF spectrum with these signals that affect other carriers the TV channels.
The polluting agents are the power lines, car ignitions or home appliances.
COFDM digital receivers can be affected and work Incorrectly if the impulsive noise is
considerable; the image freezes for a moment or disappears entirely.
To solve this problem, a higher input signal level is necessary in the digital receiver.
The DAT45 antenna and MRD work together to achieve the best reception for digital terrestrial TV.
The impulsive noise can enter the network mainly via the antenna, the mast amplifier or the cable.
An antenna with a high level of directivity like the DAT45 / DAT75, adequately orientated,
will not receive the impulsive noise from the surroundings.
On the other hand, the MRD (as it is located next to the dipole) avoids the amplification of the noise that would enter
via the cable if it were situated on the mast. The diecast chassis helps to avoid the entrance of noise through the box.
The 12 dB gain, makes the signal levels higher without making the analogue channels cause the saturation of the digital receivers.
Optional Dynamic Margin Rising Device (MRD) (delivered with the assembled dipole): elimination of the impulsive noise of the Digital TV signal.
