ABSTRACT:
A bi-directional MMDS/ITFS response converter and feed system connected to an antenna for receiving MMDS programming from a central location and for receiving information/data signals from a set top for retransmission of these signals back to the central location, The bi-directional converter has a down converter connected to a first feed for down converting conventional programming signals from the first feed into a group of converted programming signals and an up converter for up converting data/information signals from the communication line into ITFS response signals and delivering them into a second feed for transmission, The bi-directional MMDS/ITFS response converter of the present invention uses a common local oscillator for driving both the down converter and the up converter and a dual feed printed circuit board having the first feed dipole printed orthogonally to the second feed dipole,
