Review: Every radio operator needs these - These are a great tool for any radio operator's tool box. They function well, seem to be well made, and work for making quick antennas. There are male and female versions, so be aware of which type is needed.
Review: Wise purchase - Connection quality is great, size of the unit is really nice. If you know how to connect them, really easy to use. They look durable enough. Functionally, I use this with my G90 and the automatic tuner and I can tune up just about anything to use as an antenna. When we return to more humane weather I will be taking this out to various sites and using everyday object to make contacts. Use these to make easy connections to your coax, whatever. It is also a really nice item to have in the tool box.

### ⭐⭐⭐⭐⭐ Wise purchase

### ⭐⭐⭐⭐⭐ Minimize LCR or create makeshift antennas, connect feed lines, etc
*by O***N on March 16, 2024*

If you have an oscilloscope or signal/function/waveform generator, or similar equipment, you need these for really short probe wires to minimize LCR, or connect multimeter probes for anything that doesn’t need proper compensated and balanced oscilloscope probes. And if you have a radio with a BNC antenna connector then this works for makeshift wire antennas and connecting up baluns and feed lines that aren’t coax. These seem pretty solid. Have both axial and transverse banana plug holes, and the usual screw type binding posts with plastic encased metal nuts and a little (transverse, that is cross drilled) hole in the posts to help hold the wire while screwing it down. They are NOT the crappy binding posts with purely plastic nuts. Also seem solid in general. These are the lowest price I found at the time for reasonable quality (but always check prices because on Amazon especially they change constantly). I got 5 even though two would do at the moment because I always end up needing more of a particular adapter than I initially think I will need.
