===75 ohm TNC===
Most TNC connectors are 50-ohm type even when used with [[coaxial cable]] of other impedances,{{citation needed|date=July 2007}} but a 75-ohm series is also available, providing a good [[Standing wave ratio|SWR]] to about 1&nbsp;GHz.<ref>{{cite web |url=http://www.hubersuhner.com/products/hs-p-rf/hs-rf-connectors/hs-p-rf-con-gr/hs-p-rf-con-gr-series/hs-p-rf-con-gr-series-tnc75.htm |title=HUBER+SUHNER TNC 75 Ohm series (EN) |publisher=Hubersuhner.com |date=2010-10-28 |accessdate=2011-01-12 |url-status=dead |archiveurl=https://web.archive.org/web/20110712230224/http://www.hubersuhner.com/products/hs-p-rf/hs-rf-connectors/hs-p-rf-con-gr/hs-p-rf-con-gr-series/hs-p-rf-con-gr-series-tnc75.htm |archivedate=2011-07-12 }}</ref> These can be recognized by a reduced amount of [[dielectric]] in the mating ends.  They are intermatable with standard types.
