Amplica C Band Low Noise Amplifier (LNA)
Model CD305329


The first CATV satellite downlink frequencies were in the C Band.
This was the C Band amplifier that would be mounted on the "dish"
portion of the satellite receiving antenna.

C Band LNA's used a heliax waveguide cable to connect to the
receiver at the Headend. This was practical if the satellite antenna
was close to the reciever location. If the Headend was located farther
that this amp could accomidate a block converter was used to
convert the C Band (3,7 to 4.2 GHz) to a lower block of frequencies.
This allowed the operator to use coaxial cable and place the TVRO
(television recieve only) satellite antenna at a much farther distance.
This is an example of the block converters that were used.
