The antenna that has been shipped with the BS11 is a so called sector-antenna. That means it is designed not to cover only a part of the area around the BTS. And it has a gain. The gain comes from the signal that is bundeled and sent into the sector. The advantage: You can use several BTSs to cover a cell (Each cell sector has its own BTS ==> More calls) and you can cover more distance with less power.
What is good if you want to run a mobile network is bad for experimental proposes. For us an antenna that covers the area around the BTS with a nondirected signal (like a donut) is perfect - so lets build one, out of a pice of old coax-cable and a BNC connector. (You can use the endigns of an old networkcable too)
