The thing to remember about antennas is they are passive so any gain you get comes at a cost. That is why I like hyperlink and Tesco because they provide the lobe printout that shows gain graphically in 3-d which is far more important than a rated gain of an Omni directional. I high gain Omni- directional usually has a high horizontal gain with very little in the vertical. This is great in a single story building but not be good if you are also trying to cover the office above you.

I've got Cisco 1200's (RP-TNC) and have thus far used lots of their ANT4941 rubber duckies, but have to wonder what kind of difference other people might be seeing with some of the third party higher gain rubber duckies. We did some initial surveys and did not see that great a difference (hyperlinktech HG2405RD) , but I'd be happy with more input from folks. Comments?
