[Karlnet] ISP Base and back haul questions

["hfl-lists" <hfl-lists@stormcrows.com>]

Quick version of question: Can a KarlNet ISP Base link up with another
KarlNet ISP Base?

Long version if I am unclear above:

Can I do the following:

Tower 1:

3 sector antennas hooked up 1 sector per radio (3 radios).  All in KarlNet
mode.

tower 2:

1 Omni antenna on 1 radio and 1 grid pointed back at one of the 3 sectors on
tower 1 for back haul?

Would tower 2 be able to hook up correctly to tower 1?  Could I route
instead of bridge and still have one of the 'client' sector antennas on
tower 1 correctly associate?

OR instead must all back hauls be one radio on each side dedicated to
nothing but back haul?

Thanks.
