The purpose of multiple antena's on a router?

[ZeroShade]

If an antena on a router broadcasts the wireless signal... and all three atena's on my broadcast the same signal... all with the same range (which is what I'm assuming)... whats the point of three. Is the range tripled? I don't understand why?

Hello,

It isnt that the range is tripled but the signal strenght is tripled. This will allow you to have better signal strength within the devices range. Without the 3 antenna's you might not have full signal strenght when you are 100 yards away compred to have full strength when you are 100 yards away. I hope that helps you a bit.

Cheers,
Mak

If the antenna's are all the same length yes that's right, but I thought that when a router/whatever has antenna's which are different lengths they were for different frequencys. Someone correct me if I'm wrong because I have really no clue if that's right, so...
