APC is useless if the antennas are not aimed properly or the distance is excessive for the antenna gain. These conditions will cause the transmitters to pump out full volume, and if the antennas are your lower gain variety that means spraying noise everywhere.
I would recommend leaving the nice tight 6 foot dishes. That simple rule keeps the band clean for those long distance shots, instead of polluting it for close in shots. You guys have to start asking yourself what you are doing wrong if you continually need more bands. The growing trend to higher power and wide beam antennas has to stop. We are now doing a shot with 3 foot antennas and the CM9 Atheros radios in the 5 GHz band that is just over 52 miles and pulling -71 to -77 dB (variance through the day), yet I see people lining and almost drooling for the 400 mW high power cards. In short, most guys have little RF knowledge and they naturally take the easy way. I would expect to see 400 mW cards and patch antennas if the rules get changed as you are proposing. I say that is a mistake. Regards, Lonnie On 8/4/05, Marlon K. Schafer (509) 982-2181 <[EMAIL PROTECTED]> wrote: > Hi All, > > For those that don't know, the 6 gig band is licensed ptp only.
