Hi, I got the PBTi 800mhz, my airport used to have a really poor reception in my home made of bricks, since I used this advice the reception increase consistently, BUT... The battery life decrease a lot, I used to get as far as 4 hours and now I have about 2.30 min as much with the bright set to minimum. This happend to me.
