Frequently Asked Questions

Will this work with my Baofeng UV-5R?

Yes. onelinkmore lists the Baofeng UV-5R and UV-82 as compatible, along with Yaesu, Kenwood, and Alinco handhelds that use standard SMA connectors.

Which of the 12 adapters do I actually need?

The kit includes 3 of each combination: BNC female to SMA female, BNC male to SMA male, BNC male to SMA female, and BNC female to SMA male, so every scenario is covered without measuring first.

Can I use these on an RTL-SDR dongle?

Yes. The RTL-SDR Blog V3 dongle is listed as compatible, which lets you feed a BNC scanner or rooftop antenna into an SDR receiver.

How much signal loss do these adapters add?

The manufacturer rates insertion loss at 0.2 dB or less up to 3 GHz per adapter, at 50 ohm impedance. Chaining multiple adapters stacks that loss.

Will these fit my WiFi router antenna?

No. onelinkmore specifically notes the kit is not for WiFi routers or RP-SMA gear. These are standard SMA only.
