Coax Connector – RP-SMA Male Crimp Type for all RL-LMR-400 and 100 type cables

Male RP-Sma WiFi - Wireless Coax Connector

High Quality, RP-SMA type connectors, are the heart of your Coax to router interface. We’ve installed tens of thousands

WiFi connectors are the heart of an antenna system which requires coax cable. There are literally tons of WiFi connectors on the market. This style of connector has been around since the early days of Microwave, and is good from DC to 18 GHz. RadioLabs RP-SMA male connectors are the highest quality connectors in the industry. We make so many cables, this is not a place to save money when making a WiFi Coaxial Cable.  for use with either LMR100 or LMR400 coaxial type cable. It is a crimp style connector making it easy to attach. The center pin is soldered on to secure connectivity between the connector and the cable and is the perfect connector for multiple objectives.

Male RP-SMA Coax Connectors for WiFi – Wireless Systems

RadioLabs has been in business since 2001. We have installed tens of thousands of RP-SMA Male connectors since we entered the business. Our connectors have always been the best in the industry, selling to large corporations, consumers and developers. We have bulk pricing on larger quantities of connectors, with lots of 10, 100 and 1000 or more. RadioLabs has been crimping these on cables since the early days of WiFi, because the RP-SMA Male is the most common connector. Most WiFi Routers and Access Points, use the RP-SMA. These connectors are different than cellular or special electronics requiring an SMA Connector.

Most Popular WiFi Coax Connectors require an RP-SMA Male

RadioLabs high power WiFi routers, use the RP-SMA Female connector on the back. This is the most popular connector used for WiFi. So, they require the Male type connector to fit it. If you plan on connecting a cable to your router, to run WiFi to an antenna, this is the connector you need. RadioLabs has never skimped on the quality of our connectors, and never will. Antenna systems require the lowest loss possible, to get the signal from your router, to the connector first, then, through the lowest loss WiFi Coaxial cable, then, into another connector, where it finally reaches the antenna. Starting your very low power WiFi signal off, into a low cost connector is pointless. It’s like putting a high power engine in your car, but skimping on tires. 

RadioLabs Male, RP-SMA WiFi coaxial connectors, will last a lifetime, minimizing corrosion. The gold plated center pin, mates perfectly with the gold plating on your router or access point. This translates to a connection which will never corrode. If you’re looking for the best possible WiFi coax connectors, use the same connectors we install and never have a problem.
