## Customer Reviews

### ⭐⭐⭐⭐⭐ Works Good and Size I needed
*by M***N on May 20, 2025*

It works great. Needed to test the harmonics on my HT radio. I use the Tiny SA Ultra spectrum analyser and it cant handle full power of the radio. So use the attenuator between radio and analyser.

### ⭐⭐⭐⭐⭐ Just what I needed for my TinySA
*by D***O on September 20, 2024*

With these attenuators I'm able to connect my 2-way radios directly to the spectrum analyzer without risking burning it out. One of my radios reaches up to ten watts. I use the 40dB and 20dB in series to bring the power into the correct range for the Spectrum Analyzer. The 40dB model measured 41.5dB attenuation when I tested it with my NanoVNA. The 20dB model was spot on. So I set my TinySA to -61.5dB gain, hooked up the radio, and got accurate power measurements as well as useful analysis of the signal the radio transmits. I may pick up a couple more of these in other attenuation values for even more flexibility.They do get a little warm. Not hot, just warm. They seem great.

### ⭐⭐⭐⭐⭐ A must have if you use a HT with Tiny SA or Antenna Analyzer
*by W***S on December 17, 2024*

Don't damage your Tiny SA (spectrum analyzer) with too much rf input!Use one or a couple in series to reduce the power input to an acceptable level.Remember to use a unit of the appropriate wattage, you can burn these out.Also, prevent interference by using this as a dummy load.Wayne
