Sipeed MaixCAM AI Vision Board (SG2002 RISC-V, 1 TOPS NPU, WiFi 6) βΉ8,999.00 Rugged Connectivity for High-Vibration Environments. While SMA is great for desktops, TNC (Threaded Neill–Concelman) is the connector of choice for industrial, avionics, and heavy-duty GPS applications. It features a robust threaded coupling that handles vibration far better than standard BNC or SMA connectors. This U.FL (IPEX) to TNC Male Connector Cable allows you to connect standard embedded modules (like GPS receivers or LoRa radios) directly to external TNC antennas or bulkheads.
Technical Precision: TNC Male (Standard)
Connector Type: Standard TNC Male. It has Internal Threads and a Solid Male Pin in the center.
Compatibility: Connects to TNC Female jacks (External Threads + Female Socket), commonly found on Trimble/Garmin GPS antennas, Cisco industrial WiFi APs, and UHF radios.
Cable: Uses flexible 1.13mm Micro Coax to easily route inside tight enclosures without stressing the tiny U.FL connector.
Connector A: U.FL (IPEX 1 / MHF1) Female
Connector B: TNC Male (Standard Polarity)
Pin Configuration: Male Pin (Center)
Thread Type: 7/16-28 UNEF (Internal Threads)
Cable Type: 1.13mm Micro Coaxial
Impedance: 50 Ohms
Length: 15 cm
Frequency Range: DC to 6 GHz
Insulation: FEP (Fluorinated Ethylene Propylene)
High-Precision GPS: Connecting RTK GPS modules (u-blox F9P etc.) to rugged TNC survey antennas.
Industrial WiFi: Interfacing embedded WiFi cards with heavy-duty TNC bulkhead antennas.
Legacy RF: Connecting modern SDRs or modules to older commercial radio chassis.
⚠️ Connector ID:
TNC Male: Looks like a BNC connector but has Threads instead of a bayonet twist-lock.
RP-TNC: Often used on Cisco WiFi. RP-TNC Male has a Hole (Female contact). This cable is STANDARD TNC (Pin).
Usage Rule: Check your antenna/device. If it has a TNC Female jack (Hole + Ext Threads), this cable fits.
What's Included:
1 x U.FL (IPEX) to TNC Male Connector Cable (15cm)
Compatible Upgrades:
Adapter: TNC Female to SMA Male (if you need to convert it back to SMA).
Antenna: TNC Rubber Duck Antenna (433MHz / 900MHz / 2.4GHz).
Is this the same as BNC? No. TNC is "Threaded BNC". It looks similar but screws on. BNC twists on. They are not compatible.
Does the TNC connector have a pin or a hole? This is Standard TNC Male, so it has a Male Pin in the center.
Will this fit Cisco WiFi antennas? Check carefully. Many Cisco antennas use RP-TNC (Reverse Polarity). If your antenna has a pin, you need RP-TNC. If your antenna has a hole, you need this Standard TNC.
What is the cable length? 15cm.
Is this good for GPS? Yes, TNC is the standard connector for high-end survey GPS antennas.
Is the IPEX connector compatible with M.2 cards? No, M.2 cards use IPEX 4 (MHF4). This is IPEX 1.
Is the cable 1.13mm? Yes, flexible 1.13mm coax.
Is TNC better than SMA? It is mechanically stronger and handles vibration better. Electrically, they are similar (50 Ohm).
Can I use this outdoors? The TNC connector is fairly weather-resistant when tightened, but the U.FL end is for internal use only.
What is the impedance? 50 Ohms.
Is the connector rotating? The coupling nut rotates to screw on; the body is fixed.
Will this fit a Mini-PCIe card? Yes, standard Mini-PCIe WiFi/LTE cards use IPEX 1.
Is it waterproof? No, not IP-rated by itself.
Can I use this for 915MHz LoRa? Yes.
Does it come with a nut/washer? No, TNC Male is a plug. It screws onto a bulkhead jack; it does not mount to a panel itself.
Is the contact gold plated? Yes, the center pin is gold plated.
Can I use this for 5.8GHz? Yes, TNC works up to 11GHz.
Why is the connector so big? It is designed for ruggedness and ease of handling with gloves, unlike tiny SMA connectors.
What is the thread size? 7/16-28 UNEF.
Can I extend it? Yes, with a TNC Female to Male extension cable.
