Other than the obvious $20 each, what is the difference between TNC

connectors and BNC connectors?



Why do I want to spend that much more for the connectors?  Other than they

are required by Garmin on the GNS430W reason??

   One is threaded, one is bayonet lock. Both perform as advertised.

   Connectors are like laundry soap. There are what appears to be dozens

   of brands . . . most mfg by a handful of companies. Is one soap

   markedly better than another . . . maybe but it's hard to tell

   sometimes.



   Take a look at:

   This is but a small sample of the range from which one might

   select coax connectors. Aboard aircraft, there are few reasons

   to depart from RG400 coax and BNC connectors . . . but there's

   no accounting for taste.



   As to the $20 TNC connector, shop around a bit.

   There's no reason to pay that much for a TNC connector.

    Also, if you have a case where your installing a new

    device having a TNC and it replaced similar device

    with a BNC, you can use an adapter like:
