How do I connect TV cables to this signal booster unit?
The amplifier appears to have Belling-Lee connectors (Wikipedia) while the cables look like they have "F" connectors
 (Wikipedia). Assuming you are in Europe, you should be able to find adapters. If you are in the USA, BL adapters are hard to find but I've gotten them from Radio Shack in the past.
