Better, but not a security solution. Unless you're talking about a laser, beamwidth is not a quantitative measure. You can't define an antenna's beamwidth any more than you can define the boundary of the earth's atmosphere. Antenna spec sheets normally state their beamwidth as the angle where the signal is diminished by 3 dBi (~50%), but even here there's no firm standard. That said, it's good practice to keep the beam as narrow as is practical and reduce transmit power accordingly. This reduces the amount of noise you are spreading to the neighbours as well as the probability of others eavesdropping. db _______________________________________________ List mailing list [email protected] http://lists.pfsense.org/mailman/listinfo/list
