BNC connectors 75 Ohm versus 50 Ohm?
Jeff Liebermann wrote in
: I like Thomas and Betts Snap-n-Seal connectors: These are known generically as "compression connectors", and I recommended the BNC type earlier, because when used with either a BNC-F on the antenna, or a BNC/N adapter to an N-F they are waterproof, and neither depends critically on the retaining nut torque for good electrical connection (as do UHF, SMA and F connectors). Compression connectors do not use a normal hex crimp tool, but a tool unique to themselves, and in the rest of the world, the tools are pretty inexpensive (US20). Whilst I say they are waterproof, with force, it is possible to break the front of the connector out of the connector body in the types that I have tested. If you use ordinary (ie non waterproof) crimp BNCs, you need to figure some way to waterproof the cable jacket to the connector body. Most do not lend themselves to glue lined heatshrink for this purpose. Of course, you could always treat them like UHF series, and wrap the entire joint. Owen |
