This 4-piece kit covers every gender combination between N-type and TNC coaxial connectors, bridging two precision 50 ohm connector standards used in GPS/GNSS survey equipment, RFID systems, commercial two-way radios, and RF test instruments. N-type connectors are used on outdoor antennas, signal boosters, and test equipment ports; TNC connectors appear on GPS survey receivers, professional handheld radios (Motorola APX series), RFID readers, and instruments where TNC's threaded connection provides better vibration resistance than BNC while maintaining BNC-compatible center conductor geometry.
Both N-type and TNC are precision 50 ohm connectors that maintain their impedance specifications at frequencies well into the microwave range — N-type to 11–18 GHz and TNC to approximately 11 GHz. This makes N-to-TNC conversion appropriate for high-frequency applications including GPS L1/L2 (1575/1227 MHz), GNSS multi-band (1176–1602 MHz), cellular (700–2700 MHz), and WiFi (2.4/5 GHz), unlike UHF (PL-259) adapters which degrade above 300 MHz. All four adapters in this kit maintain the precision impedance of both connector standards.
These adapters are for standard TNC only — not RP-TNC (Reverse Polarity TNC). Standard TNC male has a center pin and external threads; standard TNC female has a center socket and internal threads. RP-TNC has the opposite center conductor gender. Cisco Aironet access points and some Motorola commercial radio antennas use RP-TNC. Verify your equipment uses standard TNC before ordering.
Frequently Asked Questions
TNC (Threaded Neill-Concelman) connectors are used where BNC's bayonet lock provides insufficient vibration resistance, but N-type's large size is unnecessary. Applications include professional GPS/GNSS survey receivers and antennas (Trimble, Leica, Topcon equipment), Motorola APX series commercial radio accessories, RFID reader antennas, certain military and aviation radio equipment, and RF test instruments that operate in environments where vibration could disengage a bayonet-lock BNC connector. The threaded coupling nut provides positive locking under sustained vibration.
Professional GPS/GNSS survey antennas typically have N female ports. GPS receivers with TNC ports have TNC female sockets. To connect: you need a cable with N male on the antenna end and TNC male on the receiver end. If connecting directly with an adapter (no cable), use N Female to TNC Female — this adapter joins the N female antenna port and TNC female receiver port if both are exposed female connectors on your specific equipment. Verify the gender of each port on your actual devices before selecting the adapter.
Many Trimble GNSS antennas use TNC female ports on the antenna body and N male connectors on the cable. Trimble receivers vary by model — some use TNC, some use N-type, and some use proprietary connectors. This kit covers N-to-TNC conversions appropriate for connecting Trimble antenna systems to N-type infrastructure or for adapting between N-type test equipment and TNC-port Trimble receivers. Verify your specific Trimble model's connector type in the product manual before assuming compatibility.
TNC and BNC use identical center conductor geometry and 50 ohm impedance — the only difference is the locking mechanism. BNC uses a quarter-turn bayonet lock rated to approximately 4 GHz; TNC uses a threaded coupling nut rated to approximately 11 GHz. For GPS L1 (1575 MHz) and L2 (1227 MHz) frequencies, both connectors perform adequately electrically. TNC is chosen for GPS survey equipment because the threaded connection prevents accidental disconnection during field use on unstable terrain or during transport, where a bayonet BNC could work loose.
RFID (Radio Frequency Identification) readers communicate with tags using frequencies in the 860–960 MHz (UHF RFID) or 2.45 GHz (microwave RFID) ranges. Many RFID reader antenna ports use TNC female connectors for their secure threaded connection — important in industrial environments where the antenna may be subject to vibration and impact. N-to-TNC adapters from this kit allow N-type antenna systems to connect to TNC-port RFID readers, or allow N-type test equipment to interface with TNC-port RFID equipment for antenna characterization and system testing.
N-to-TNC connections occur in all four gender combinations depending on which side of each interface is the cable end and which is the equipment port. A TNC female antenna port connecting to an N male cable needs TNC Female to N Male. An N female test instrument connecting to a TNC male cable needs N Female to TNC Male. Including all four combinations eliminates the need to determine the correct gender before purchasing — one adapter from this kit will be correct for any N-to-TNC interface scenario.
