My apologies for noob question, please help me to understand this first time

I'm going to put together an access point for my little office - a routerboard with one G and one N card.

Well, I looked at 411 series cases, they have holes for two antennas.

But I have two cards - how can I squeeze all the antennas having a case like 411 or 433?

Make additional hole for the last one or use pigtails and mount them outside the case on selfmade stand.

Hello,

If You want to use two radio cards You'll need to buy RB433, RB411 supports only one radio card.

for example RB411R has miniPCI slot and built in radio.

Right, I guess my question is - do I really have to use 4 antennas for 2 cards?
Those off the shelf dual radio N routers usually have 2 or 3 rubber duckies...

if you have MIMO then better use 802.11n with all available channels for improved speeds. With R52n you can get 300Mbps air rate (that is 2 channel)
