A great addition to any radio or software defined radio with female SMA input, including our NESDR SMArt series and HackRF | 8 male SMA adapters in total, allowing you to connect the following antenna types to your radio: N-connector, F-connector (aka 'Coax'), SO-239 (aka 'UHF' or 'PL-259'), BNC, MCX, PAL, RP-SMA, and SMA (female). Full list in description below | A convenient carrying case is included. Great for field use! Ample room to house your NESDR SMArt or NESDR Nano SDR | 50 Ohm, low-loss adapters--lower loss than any RF cable adapters | NOTE: RP-SMA looks similar, but is not the same! These will not work for RP-SMA. RP-SMA is generally only used for things like WiFi equipment, not radios, but if you are unsure please contact our support team for assistance
