## What is RF Tools?

The RF Tools App from HUBER+SUHNER AG is a useful tool, which shows the relation between RF specific values like impedance, wave length, return loss (VSWR) and signal delay including their conversion. On top of this, the RF Assembly Calculator provides an easy comparison of H+S RF cables and assemblies in different configurations and in different environments. It offers a straight access to technical specifications such as insertion loss and power rating.
 
Above all, engineers and students will love this handy and helpful tool.

### 3/5 — no wavelength to frequency

*2020-03-27*

seems silly that there is frequency to wavelength but not vice versa

### 1/5 — Poor!!!

*2016-07-03*

This is for specific group of people or technicians.  No instructions and no idea how it works.

### 5/5 — very useful

*2015-04-14*

good job.

### 4/5 — Great app for any RF tech

*2014-03-05*

### 5/5 — Great app

*2012-07-21*

Great app
