onelinkmore BNC Male Plug to 2X 4mm Dual Banana Female Jack Socket Binding Post RF Coax Coaxial Splitter Connector BNC Banana Adapter for HF Radio Antennas Oscilloscope DVM Pack of 5

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.

This gadget is excellent for amateur radio antenna experiments. I built a quarter-wave 2 meter dipole for my handy talkie and it worked well. So I bought a few more to do experiments with. Hat tip to VA7BWX for suggesting this device to me!

※追記※ 中に不良品があり、ひどい目にあいました。安物買いの銭なんちゃらを地で行く体たらく。コストをかけてちゃんとした製品を選びましょう。こちらオススメできません。 電気的には特に問題ないようですが、端子部分が軽い力でもクルクル回るのは気になります。

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.

Exactly what was needed.
