It works in the other way as well, with two receiving antennas the phase differences between the signals are used to cancel out or suppress unwanted signals. If you use two identical antennas, Antenna diversity will help the receiver circuit fighting signal reflections, as others already wrote. I can assure you that my kindergarden age doesn't enable me to down-vote the answer. If you require a cable length longer than 2 foot with the antenna, then you would And given what you are describing it sounds like you are in a not-so-great area so I don't expect more antennas to help. Not knowing much about routers, i would assume it would give out a stronger signal. My question is, if I purchased a higher grade Huawei router such as the B525 router which has 2 antenna ports on the back, would this provide a stronger and faster speed if I plugged both antenna cables into the back of it? I believe by your answer then is it valid to state that with a better bit rate (through a sophisticated modulation technique) and better SNR the signals travel a longer distance? @AndrejaKo yes, that's included in the 'other, cleverer, more complicated ways' I referred to. Given this SNR the modulation technique is selected. The mega antenna is going to boost your Wifi signals for sure. However the next model up goes up to 5 bars I believe.
