Boosting a Linksys Access Point

The Linksys WAP54G is shipped with two 5 dBi antennas.
Here I show two ways to increase its power and working area: perhaps using both solutions provides too much power to be legal… but I don’t use them at the same time, of course. :)
In place of the 5 dBi antenna on the left, there is a 500 mW booster powering two 12 dBi SMA antennas (!), while in place of the 5 dBi antenna on the right, there are two 7 dBi greater Linksys models.
The market offers connectors of different kinds and it’s easy to get confused: this was the main problem while assembling the system.
Among the parts mentioned above, I used – or bought, at least :) :

• 2 RP-SMA Male to RP-TNC Female Adapter Wireless WiFi RF;
• 1 RP-TNC Male to RP-SMA Female Adapter Wireless WiFi RF;
• 1 SMA Female to SMA Female Plug Coax Adaptor;
• 1 splitter (2 way);
• 1 pigtail cable N-RP SMA;
• 1 pigtail cable RP-TNC.

The result: I can’t provide a scientific measure but the power of the signal on the furthest corner of my WLAN area has doubled.
Notice that the two original antennas are half the size of the “small” antennas you can see on the right part of the first picture! :)
