- Upgraded Antenna Analyzer V4.3：The Upgraded NanoVNA-H4 Version features a larger resistive touchscreen (4 inches)and widened frequency scan range (10KHz-1.5GHz) to measure RF S11 (reflection), S21 (forward gain), and related parameters. Designed with an SD Card Port, this new nanovna is convenient for your data storage and sharing
- Must-Have for Radio Operator or Enthusiast: This spectrum analyzer will be a nice little addition to the workbench, which is a very handy analyzer for the amateur radio operator or radio enthusiast. The Smith chart is very handy to have as well as being able to see reflected db. You get a lot of information from this little unit, connect it to your PC, and can save a .cal file for a certain frequency which saves you time
- Improved Performance & Built Quality： The 4-inch NanoVNA-H4 is a great upgrade to the 2.8" screen. Its performance is outstanding, the display quality is very crisp. This nanoVNA is perfect for evaluating antenna resonance and SWR, The 4-inch screen is easy to read and the touch screen is responsive and can be navigated with a finger. With good accuracy and a built-in 1950mAh rechargeable battery, can be used in the ham radio shack
- PC Control: This nanoVNA can be controlled by a PC using the software VNA Saver. The software has a number of features such as the ability to run many smaller frequency sweeps (the nanoVNA takes 101 measurements across a sweep) and combine the results to get a higher-resolution sweep. There are also averaging functions that allow you to do time-domain reflectometry which can be useful for detecting damaged cable runs. It also allows easier reading off of data points using markers
- Complete VNA Set, Out of the Box: With all the attachments, this antenna analyzer kit comes in quite a nice cardboard box. Inside content includes: NanoVNA-H4 (with 1950mA-h battery) x1, USB Type-C data cable x1, 15cm SMA male to male RG316 RF cable x2, SMA male calibration kit - OPEN x1, SMA male calibration kit - SHORT x1, SMA male calibration kit - LOAD x1. Great for troubleshooting antennas and improving performance
