since you are all busy becoming high site experts, how about a little advice, I'm rather worried about my current mywireless configuration, theres a dish sitting on the highest point of my roof, up till now, lightning hasn't been a problem, being winter and all, but whats going to happen when summer hits us, do you get some sort of protector between aerial and modem/accesspoint, how does it work? where do we get it. Is it necessary???
