Antenna Gain and diversity

Unanswered Question
Sep 17th, 2008

Hi guys!

I've heard that "high" gain antennas shouldnt be used in diversity configuration (antennas like 1728), is this true?

Also.. while using this antenna, I dont see much difference in coverage than using the regular 2.2 dBi antennas that comes with the 1242 AP. At least in numbers the coverage should be like 2 times bigger, right?

Any tips or explanations are greatly appretiated :)

changing the gain of an antenna also changes the shape a little of the radio footprint.I still struggle a little with this but as I understand it if you double the gain you give the signal more power and a flatter radiation pattern, forgetting about panel and yagis for now. This greater power punches the signal through objects more easily not necessarily improving the distance significantly.

I havnt heard of any reason not to use them for diversity but if its a relatively clear space there isnt that big an advantage using diverse antennas its more for internal apps where there are more obstacles

This might help
