Amphenol TNC Developed in the late 1950's, the TNC stands for threaded Neill Concelman and is named after named after Paul Neill of Bell Labs and Amphenol engineer Carl Concelman. Designed as a threaded version of the BNC, the TNC series features screw threads for mating. TNC are miniature, threaded weatherproof units with a constant 50 Ω impedance and they operate from 0 - 11 GHz. There are two types of TNC connectors: Standard and Reverse Polarity. Reverse polarity is a keying system accomplished with a reverse interface, and ensures that reverse polarity interface connectors do not mate with standard interface connectors. Amphenol accomplishes this by inserting female contacts into plugs and male contacts into jacks.RG stands for "Registered Gauge" The numbers of the various versions of RG cable refer to the diameter and internal characteristics of the cable, including the amount of shielding and the cable's attenuation, which refers to how much signal loss there is per length of cable.
There is no meaning to the numbers used for different cables types; they are arbitrary labels assigned long ago.
Most non-industrial coaxial cable is now RG-6, although the previous thinner lower-quality standard of RG-59 is still used in some applications and older homes. Commercial installers may use a thicker RG cable, like RG-11 (which is only used if the distance from the source tap to your point of termination at the home is greater than 200 feet)
Be aware that all cables (and their connectors) come in a variety of qualities

Reverse-polarity TNC (RP-TNC) is a variation of the TNC specification which reverses the polarity of the interface. This is usually achieved by incorporating the female contacts normally found in jacks into the plug, and the male contacts normally found in plugs into the jack. RP-TNC connectors are widely used by WiFi equipment manufacturers to comply with FCC regulations designed to prevent consumers from connecting antennas which exhibit too much DB gain and breach compliance. This connector is common on WiFi or Broadband Routers and Antennas from Cisco, Linksys and other lines of Wi-Fi products. RP-TNC can also be abbreviated as RPTNC.

SMA connectors are semi-precision, subminiature devices that provide repeatable electrical performance from DC to 12.4 GHz with flexible cable. These devices offer broadband performance with low reflection and constant 50 ohm impedance. These properties, along with minimum attenuation and low VSWR have made the SMA extremely popular in the microwave community. The SMA design has been broadened to accommodate many interconnect requirements and is available in pressure crimp, clamp and solder terminal attachments. SMA design parameters have incorporated the considerations of balancing cost, size, weight and performance to yield the best value in your microwave system. Among typical applications are components such as dividers, mixers, amplifiers, trimmers and attenuators. SMA connectors are also used to provide interconnections from printed circuit board stripliness to coaxial cable.SMA is available both in Standard and Reverse Polarity. Reverse polarity is a keying system accomplished with a reverse interface, and ensures that reverse polarity interface connectors do not mate with standard interface connectors.
