RP-SMA type WiFi Coax Connector

Our high quality RP-SMA wifi connectors come with the connector base, crimp ring and pin

RadioLabs RP-SMA Female type coaxial connectors for WiFi – Wireless cables, are high quality solid metal connectors. These crimp style WiFi coaxial connectors are the same connectors used on all RadioLabs Cable products, but also the same quality connectors used by professional installers of all WiFi Systems.

The connectors are plated, solid brass outer jacket, plated for long life, with a gold-plated center pin. The pin is the solder on type, or crimp if necessary, but crimping center pin is not recommended for long term use. These connectors come in a package, with all 3 parts shown included. On request, we will also include a small piece of heat shrink for around the base of the connector.

RadioLabs installs thousands of these connectors every year and we ensure you are getting the highest quality, most rugged connector possible. There are literally hundreds of styles of coax connectors that have been invented. RadioLabs supplies our customers with only the highest quality, best connectors made and do not skimp on quality to simply save a few pennies. Other very LOW COST connectors available on bargain websites, can and will degrade your WiFi performance instantly, losing DBs, resulting in a vast degradation in your signal strength.

High quality RP-SMA WiFi Connectors – Crimp type

All connectors are not alike. Many brands we have ordered were not sufficient quality to install, or sell to our customers. If the metal is cast molded, made of tin, does not have clean threads or if anything is not 100% top quality, we will never sell them to a single customer. One bad connector can destroy an installation and waste dozens of hours trying to sort and troubleshoot the problem. As installers in the field, we know the hardships of bad equipment, so we ensure every connector, cable or product we sell is absolutely reliable.

Note: These connector fit all style WiFi coax, including LMR-400, or LMR-100, RG-36, etc.
