I have never heard or read that one is for sending and one is for receiving. I don't have the link but i remember doing research for a wireless project a year ago or so ago and the manufacturer (I think i read it on HPs site) recomended setting one vertical and one horizontal. I think the standard to reduce interference from neighboring APs is to set them to different channels. Now i have to go look for a link that details the operation.
after thinking more on it, i used HP and linksys access points as a long range bridge by adding directional antenas. The directional antena only connected to one antena connection and provided two way communication to another access point about 400yds away. If the duel antenas were set up so one was a send and one was a receive there never would have been any communication. The access points on the far end of the link did not have directional antenas.
The intention was not to indicate that one antenna was for receive and one for transmit, they have both these functions, but only one function at any given instant. The reduction in interference is mainly for say, building to building links in which there are multiple transceivers in the area.
Oh ok I misundestood what you were saying.
Although I didn't have the link bookmarked I still remember a recomendation to have one antena horizontal and one vertical on a given access point. Maybe someone else can reference a site or dispute my memory.

Dear folks,

As my invastigation vertical antennas are more stable to use. Practically I will test shortly and let you know
