MMDS Rx antennas

MMDS converter with integrated filter and dipole

The antennas are designed for the reception of analogue or digitally modulated MMDS programmes. They have a built-in highly selective filter on the input, therefore they are highly resistant to interference, in particular in areas with strong signals from GSM or UMTS mobile networks, or from airport radars. The "21Y" antenna is certified.
