Hi,

I'm assessing an AP which has 4 RPSM and is dual radio with RPSMA connectors for external Antennas.  I would like to use a antenna which is 3 element which has 3 pigtails.

Can anyone clarify if the each element represent a single transmit and receive chain and if for instance connecting all 3 RPSM sockets to antenna would result in 2 sets of transmit and receive chains (2 per radio)

Let me know if this is not clear enough

If you mean something like http://www.l-com.com/item.aspx?id=28947
those are 3 separate antennae, and connecting all 3 should result in 3 sets of transmit and receive chains per radio, if that's what its radios are capable of.
See http://en.wikipedia.org/wiki/IEEE_802.11n#Number_of_antennas

If you have 4 RP-SMA connectors on the AP, you might consider http://www.l-com.com/item.aspx?id=28246 instead... then you could use all 4 of them with one unit if you wanted to.

Well, yes... but what I don't understand is exactly what it is you're asking.  :-)
If you want to know if that's going to work for what you want, I have no idea.
I don't even know what antennae and APs you have, let alone where you plan on installing them.
