There are quite a number of coaxial WiFi antenna cable connectors available in the market currently. Some of the popular ones include:
- SMA & Reverse SMA: SMA is a small connector but larger than micro. It has traditionally been used mostly in HAM radio and to a lesser extend in WiFi. Reverse SMA is also known as RP-SMA and has been more widely used in WiFi than SMA ever was.
- RP-TNC is Reverse Polarity TNC and is closely related to BNC, below. RP-TNC connectors are used on Cisco Linksys WiFi gear.
- BNC connectors are used in RF as well as video applications. However, they were initially meant to be used for military purposes. Their frequency limit is 2GHz. Both the male and female connectors have plastic dielectric to bring about losses during cases of extremely high frequencies. The connectors are available in both 75 ohm and 50 ohm versions. BNC is an acronym for ‘Bayonet Navy Connector’. At times, they are referred to as ‘Bayonet Neil-Concelman’ connectors.
- RCA- They are also referred to as Phono plugs and jacks with a frequency limit of 10 MHz They come in the form of circular press-on connectors used in video as well as audio composite connections. The most recent RCA connectors to hit the market are colored in nature (white, yellow & red).
- TS- TS in this case is an acronym for Tip-Sleeve. It is basically used for two-conductor connections. There is also the TRS which stands for Tip-Ring-Sleeve used in connections involving three conductors. In the past, they were used on phone switchboards. However, they are today used in various audio instruments. Their frequency limit is 100 KHz.
- F Series- This series of connectors are used for antenna to television connections. You can the push-on design or the coupling thread design depending on your preference. Their frequency limit ranges in-between 1GHz and 250 MHz
- UHF- This particular kind of conductor is as old as the UHF/VHF technology itself. They date way back to the late 1920’s. The male connector is PL-259 while the female connector is the SO-239. UHF connectors are primarily of non-constant impedance. Their frequency limit is 300MHz. However, there are those with a frequency limit of 200MHz. It all depends on the quality.
- Other common types would include the GR874, C-series, SMA and APC-7 connectors.
