when looking for a new arial for my freeview box I was told that a small satalite dish connected directly to the arial socket on the freeview box would work better for best digital reception . does anyone use this method.
armacomroll: Satellite dishes receive signal frequencies around 10Ghz which are guided into a trumpet-shaped box called an LNB (low noise box). This gadget does two things; it selects polarisation, and it reduces the carrier frequency by 90% to down-feed the satellite receiver.
A terrestrial receiver does not provide the 18 volt power and control needed by the LNB.
If a Universal LNB is used it will also require a 22kHz signal at around 0.5v p-p.
This signal is required to switch The LNB's (low noise block) local oscillator to the high or low band.
A satellite system you were thinking about is called "free to air" Your set top box is free to view and can only be used with a terrestrial aerial system or the provision of a signal working within the same parameters of the transmitted terrestrial digital signal.
Free to air and free to view are basically the same thing - I'd made it clear that DTB is only available via a Freeview set top box/PC digital TV card or USB stick in conjunction with a standard wideband TV aerial.
Satellite equivalents are used for FreeSat and picking up the many free to air transmissions from various satellites, but not necessarily broadcast in English.
