Doubling the antennas will in theory double the total received power... Expressed logarithmicly, that's 3dB. In practice you also have to consider loss in the cabling and combiner network as well as the fact that each antenna may not actually receive an equal amount of energy. 2 to 2.5 dB of gain would be a realistic estimate for properly ganging two identical antennas.
