## Description

Review: Good quality - Durable and a perfect fit . This makes it easy to connect test equipment to cables. Compatible with all sma connectors. A great value for this set of connectors
Review: Good stuff - return loss -30 dB to 3 Ghz for a pair in series - I just got a genuine NanoVNA V2plus5 and don't have a real lab-grade load for it. That said, I do have three terminations that read close to each other (-40 dB RL on others when calibrated on one). So, I think my calibration is OK. If I put a pair of these together, I get -30 dB return loss to 3 GHz and less than 1 dB transmission loss to 4 GHz. As this is a new setup for me, you will have to use this just as a casual data point. But the VSWR plots in the listing are probably good. These are not cheap junk, they're the good stuff. I spent almost as much on a set from a well-known auction site and they are junk - connectors won't mate on some of them. So, the ones here are recommended. If you need better, it's time for Keysight, etc. Note: this is for the "upgraded" set.

### ⭐⭐⭐⭐⭐ Good quality
*by F***. on January 21, 2026*

Durable and a perfect fit . This makes it easy to connect test equipment to cables. Compatible with all sma connectors. A great value for this set of connectors

### ⭐⭐⭐⭐⭐ Good stuff - return loss -30 dB to 3 Ghz for a pair in series

### ⭐⭐⭐⭐⭐ Good mix of connectors.
*by M***E on April 1, 2025*

This set is a great mix of m-m, m-f and the reverse of SMA to BNC connectors. With these I can connect my VHF handheld to more permanent antennas. It fits my radios perfectly, and very easy to connect (the thread sizes are good). The connectors seem very well designed and high quality. Adding it into my signal analyzer, the loss from the connectors is negligible and doesn't change the impedance much at all. With these in the line I get an SWR of 1.02:1 so overall a great set.
