Actually, a 13db 90* sector means that right in front of the antenna will
have 13db gain and 45* to either side of center will have 10db gain (90* is
the -3db beam). The antenna actually has coverage to 120*. A 120* antanna
will cover to ~150*. Now none of this matters if you use three different
radios on three different channels. The only time it is important is when
you use 1 radio with a 3 way splitter.

are you planning on using one radio or three radios ? best to ask on the
[EMAIL PROTECTED] list for using one radio cause there are a few people doing
that, but three radios using dsss you can use three channels. But if three
120* sectors have overlap then two 180*'s do also, but I believe the db
level to be lower at the end lobes and shouldn't be a problem, three 90*'s
unless they are over will have null spots
