300mW (24.77dBm) + 30dBi = 54.77dBm EIRP. The maximum tx power you can *legally* run with 30dBi of antenna gain PTP is 30 - (30 - 6) / 3 = 22dBm, or 158.49mW. In other words, you're about 2X (3dBm) too high in tx power. > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf > Of > blitz > Sent: Tuesday, June 29, 2004 4:32 PM > To: [email protected] > Cc: [email protected] > Subject: Re: [BAWUG] 30 DB directional.. > > Yes, they're good, and deliver plenty gain, just make dammed sure > they're > fastened to a SOLID structure, the pattern is very tight.
