Does any one know the frequences used for Freeview?
Freeview is a free digital TV thing in the UK, don't know if its in other countrys.

In North America there is free satellite TV. It operates in microwave frequencies so a jammer would be difficult to make, and the dish focuses very accurately so the jammer must be in its focus.

In the UK we can just use a normal analog TV aerials, but some places need a high gain aerial.
I wasn't realy intending to make a Freeview jammer, i wanted to make a signal amplifer to save money on buying a high gain aerial, just that i don't know wat frequancys Freeview uses.

If you want an antenna amplifier, don't post on a thread that is talking about jamming cell phones, start your own thread.
