Spelling: RTSMAConnector
"RT-SMA" stands for "Reverse-Thread Sub-Minature type A". RT-SMA
Connectors [1] are the cousins of SMA-Connectors [2], and provide
identical performance.
Reverse-Thread connectors differ only by the direction of the
threading of the outer 'ground' contact used to hold connectors
together. In RT-SMAs [3], the thread is "left-handed", and therefore
to create a connection you lock the connector in a counter-clockwise
direction instead of the normal clockwise direction.
Reverse-Thread connectors are used on 802.11 [4] gear due to
America's FCC [5] requirements (Part 15.203) where by such equipment
needs non-standard connectors. Other modified SMA [6] solutions to
satisfy the FCC [7] requirements are to either use "reverse-polarity
[8]" or "shrouded [9]" connectors.
