KB2AH
The price of the KB2AH 1296 Mhz dual-port, circular polarized
feed horn is $250.00 US, plus shipping. These horns are suitable
for F/D ratios of 0.32 to 0.45. Made from .030 copper. Horn does
not come tuned. Not included are N connectors, hose clamp to secure
scalar ring, or mounting hardware. Provisions are made for a UG-58
connector to be attached to horn: machined, pre-drilled, and tapped
for 6-32 screws. Tuning instructions come with purchase of the
horn. Needed at minimum is a low power source for 1296 (10 dbm
or more), and a detector for tune up. Of course a network analyzer
would be the easiest way.
