RF Connector
Connecting Signals with RF Connectors
RF (radio frequency) connectors transmit high-frequency signals between devices like antennas, radios, amplifiers, and cable infrastructure. N and SMA connectors are common in cellular and Wi-Fi systems.
N-Type
N connectors are medium-sized, threaded, and weatherproof. Their durable design reliably handles frequencies up to 11 GHz, making them well-suited for outdoor Wi-Fi and cellular installations. N connectors stand up to moisture, dust, and vibration.
SMA & RP-SMA
SMA (Sub-Miniature version A) connectors are semi-precision and operate up to 18 GHz (some proprietary ones up to 26.5 GHz). Their compact size makes them versatile for integrating RF amplifiers, isolators, microwave systems, mobile antennas, and indoor Wi-Fi access points.
RP stands for "Reverse Polarity". The main difference is in the gender of the connectors. An SMA connector has a male pin in the plug and a female socket in the jack. The RP-SMA connector has the opposite arrangement - a female pin and a male socket.
Protective Tape
Silicone tape provides an effective way to enhance the waterproof and weather-resistance protection of the RF connectors. Consider wrapping the connectors with outdoor grade silicone tape, especially when using the outdoor router in challenging environments, such as coast, dust, cold temperatures, etc.
Before wrapping the silicone tape, clean the connector thoroughly to remove any dirt, grease, or moisture to ensure better adhesion to the silicone tape. Wrap the silicone tape in an overlapping spiral pattern, covering the entire connector body. Stretch the tape slightly as you wrap it to create a tight seal. Overlap each wrap by about 50% to ensure a continuous and waterproof seal.
Silicone tape is not a permanent solution. Check and replace it after a few months, especially when it's broken.
