What are Line Amplifiers?
Line amplifiers only amplify the LNB output, not the microwave satellite signal received by the dish. So, if you have poor Sky signal you must first check you have the right size dish for your region and check dish alignment with a suitable satellite meter as well as inspecting the coaxial cable feeder for water damage. If you are experiencing poor signal quality abroad, you may need buy a bigger dish and/or use a lower noise LNB to improve reception.
