 LNB   (Site not responding. Last check: 2007-10-21)
An LNB (low-noise block converter) is used in satellite broadcast reception, usually for digital television reception.
The LNB is usually fixed on or in the antenna, for the reasons outlined below.
The job of the LNB is to use the superheterodyne principle to take a block (or band) of relatively high frequencies and convert them to similar signals carried at a much lower frequency (called " intermediate frequency," or IF).

 SURPLUS LNB
For the LNB to work on 10GHz receive, then the local oscillator would preferably be working at 9GHz.The method I used to covert the local oscillator to 9GHz was to glue two dielectric resonators ‘puck’ together, using clear nail varnish, clamping the two together and leaving for about 24 hrs to dry.
Before starting to cut away at the LNB, there is one important job to be done that is to remove the pcb from the LNB housing; it’s a simple job.
Match the hole in the WG16, with that in the LNB casing, and mark the location of the lugs onto the LNB casing, drill and tap these as required to enable the WG16 to fit tightly to the casing.

 C-band Satellite Installation
The LNB is the electronic device that mounts on the feedhorn and converts that golf-ball-sized globe of RF energy into an electrical signal the IRD (receiver) can understand and use.
The biggest difference between a normal LNB and a PLL LNB is the amount of frequency drift.
Now that we have the proper LNB mounted on the feedhorn, the feedhorn mounted on the dish and centered exactly, and the dish mounted on a plumb and properly secured pole, we are ready to connect the actuator arm.

This LNB is designed specificaly for an oval dish and is likely to give poor results with a dish that is roughly circular or a dish that is taller than it is wide.
The function of the LNB is to reduce the frequency of the satellite signal.

 Satellite television - Wikipedia, the free encyclopedia
This feedhorn is essentially the front-end of a waveguide that gathers the signals at or near the focal point and 'conducts' them to a low-noise block downconverter or LNB.
The LNB converts the signals from electromagnetic or radio waves to electrical signals and shifts the signals from the downlinked C-band and/or K
Direct broadcast satellite dishes use an LNBF, which integrates the feedhorn with the LNB.

Without the LNB type being set you may have difficulties setting up, the receiver needs to know this so that it can lock on to the correct frequencies.
The bouncing signal can be caused by obstructions (unlikely if you had it working before), faulty LNB, it's unlikely that both will be faulty so try them one at a time with a direct connection, (excluding the DiseqC switch as this could also be faulty or the settings in the receiver incorrect).
