Coax Connector Types, Pictures, Information, and Descriptions |
| N
Male
Connector The N
connector
(in
full, Type
N
connector)
is
a
threaded RF connector used to
join coaxial cables.
It was one of the first connectors capable of carrying
microwave-frequency signals, and was invented in the 1940s by Paul
Neill of Bell Labs, after whom the connector is named.
N
connectors are the most common WiFi Antenna connections and are also
widely used in HAM and other Amateur Radio applications.

UHF Male PL-259 Connector The
UHF
connector
design, from an era when , also called the Amphenol coaxial connector,
is a World War II threaded RF connector UHF referred to frequencies
over
30 MHz.
Originally
intended for use as a video connector in RADAR
applications, it was later used for RF applications. This connector was
developed on basis of a shielded banana plug.
|
F Connectors The
F
connector
is a common means of connecting television signals. It is a type of
coaxial RF connector commonly used for "over the air" terrestrial
television, cable television and universally for satellite television
and cable
modems.
It was invented by Eric E. Winston in the early 1950s while working for
Jerrold Electronics
on their development of cable television. In the 1970s it became
commonplace on VHF television antenna connections, as coaxial cables
replaced twin-lead, and later for UHF also.

Straight SMA Connectors SMA (SubMiniature version A) connectors are coaxial RF Connectors developed in the 1960s as a minimal connector with a screw type coupling mechanism. The connector has a 50 Ω impedance. It offers excellent electrical performance from DC to 18 GHz. The outer shell of the male or plug connector has an inside thread and an inner pin, which can be confusing. In conventional SMA, the terms "male" and "female" refer exclusively to the inner pin or socket of the connectors. The male connector is also commonly referred to as a "plug", whereas the female connector is also known as a "socket" or "jack". |
N Female Connector
Originally, the connector was designed to carry signals of up to 1 GHz in military applications, but the common Type N today handles up to 11 GHz comfortably. More recent precision enhancements to the design by Julius Botka at Hewlett Packard have scaled this to 18 GHz. The connector is hand-tightened and has an air gap between center and outer conductors. The coupling has a 5/8-24 thread. |
UHF Female SO-238 Connector An old standard, UHF connectors are generally usable through what is now known as the VHF and HF frequencies and can handle RF power levels over one kilowatt. Despite the name it is rarely used for actual UHF frequencies as they don't work well above 300 MHz. |
Straight VS Reverse Polarity (RP) If you are among the majority confused by the Governments (FCC) boondoggle in connector governance join the crowd! We try to shed a little light here. |
RP-SMA WiFi Connectors This just confuses people who intuitively know that pins are male and holes are female! Reverse polarity SMA (RP-SMA or RPSMA) is a proprietary variation of the SMA connector specification which reverses the gender of the interface, as shown in Photos below. The term "reverse polarity" here refers only to the connector gender, not in any way to the polarity of the signal. An RP-SMA MALE connector has the same external housing as a standard or conventional SMA, however, the internal prong or pin is replaced by a receptacle or female inner pin. Similarly, an RP-SMA FEMALE has a pin like a conventional male, and the connector keeps the female outer threads. |
| BNC Male Connector The BNC (Bayonet Neill-Concelman) connector is a very common type of RF Connector commonly used for terminating coaxial cable. The BNC connector is used for RF signal connections, for analog and digital video signals, HAM Amateur Radio antenna connections, and many other types of equipment. |
FME Connectors FME (For Mobile Equipment)is a miniature 50Ω RF connector series offering excellent performance from DC to 2.0 GHz used in mobile applications and installations. The FME female is designed to be snaked through the often tight access holes or spaces of a vehicle to the desired equipment location(s). |
Straight TNC Connectors The TNC (threaded Neill-Concelman) connector is a threaded version of the BNC connector. The connector has a 50 Ω impedance and operates best in the 0–11 GHz frequency spectrum. It has better performance than the BNC connector at Microwave frequencies. Straight TNCs are used on Cellular, Ham and Microwave cables and Antennas. |
Solder VS Crimp Connectors Old School PL-259 versis newer Crimp and Compression Connectors. Which really work better? |
| BNC Female Connector Male and Female BNC Connectors come in 50 and 75 Ohm versions. Although we match impedance, 75 Ohm BNC connectors that comply with IEC 169-8 will mate in a non-destructive manner with 50 Ohm BNC connectors that comply with IEC 169-8. The Canford Group, a manufacturer of BNC connectors claims "In over 15 years and a many million BNC connectors we have no first hand experience of incompatibility between 50 ohm and 75 ohm types, other than extremely rare (and very obvious) manufacturing faults." |
Mini-UHF Connectors Mini-UHF connectors are miniaturized versions of UHF Connectors, designed primarily for use in mobile phones and similar applications where size is an important consideration. Introduced in the 1970's, Mini-UHF has a 3/8-24 thread size and operates up to 2.5 GHz. |
RP-TNC WiFi Connectors 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. |
Less Common Connectors Yep, There are more, Many More... |

At one time all connectors were straight. Boys were boys and Girls were girls then along came the Government... In order to regulate WiFi and try to create connectors specialized for it's use we have the FCC and the wonderful concept of RP (Reverse Polarity). Now we have Females with Male Pins and Males with Female innards. See the picture here of SMAs, but TNCs, BNCs, Ns and others can all be Straight or RP depending on their use. Take a look at the photos and if you don't know which you need Please Ask. |
