Why does the FLEX-3000 use a BNC connector rather than a SO-239 connector for the antenna connector?
The RF output is a BNC for the following reasons: • BNC connectors require less space and thus allow for a smaller enclosure. The FLEX-3000 is intended for briefcase portable applications as well as fixed station so chassis dimensions are a consideration. • A BNC connector can be assembled on the PCB with no wires, which is not true of a SO-239. • BNC connectors are higher in performance than SO-239s from a RF perspective. • BNC connectors have no problem handling the power levels of a FLEX-3000. • BNC connectors are a lot easier to connect and disconnect. You can push a type N connector on to a BNC for “easy connect.” A BNC to UHF adapter will be included in the box to do the conversion if required.
