Combining the output of antennas that are pointing at different locations can be tricky, as the same signals could be received by different paths, misaligned, and therefore they would interfere each other destroying themselves.
We have designed a device, the SmartKom, which is an easy-to-install professional amplifier. It allows filtering, balance, mix and amplify television signals received from up to a maximum of 3 antennas, increasing the number of channels received in a given location, avoiding the use of mechanical solutions such as rotors and enabling the distribution of all the content received from the antennas in a single input cable to the house.
