Visual Antenna Analyzer Shield
Visual Frequency Scanning Analyzer Covers 160- 6 meter bands
The VAA.exe program interface for Windows PC.
•The shield attaches to Arduino Uno R3 as a direct plugin.
• AD9850 signal generator mounts on the shield.
•Powered by USB connection to Arduino.
Scanning Analyzer visually reports SWR values over a range of frequencies.
•Reports SWR values and nodes for HF antennas from 1 to 55MHz.
•Digital control and display from your PC.
•Helps with antenna adjustments and provides suggested antenna length modifications.
•May be used to inject signals and adjust antenna traps like a grid dip meter.
•Doubles in your shack as a high-precision digitally controlled RF generator source.
Arduino R3 or equivalent
AD 9850
Perhaps, the most important component of any amateur station is the antenna. It should be well matched to the frequency used, with a low SWR. This maximizes its efficiency and transfers the maximum power radiation.
I developed this low cost analyzer to help adjust and repair my antenna farm. I find that is a great asset to my shack.
The Antenna Scan Shield kit is supplied with all components. Assembly time is about 1 hour.
We offer a completely assembled shield completely tested below if you do not have construction capabilities.
The complete Kit cost is $34.95 with free shipping and contains:
Shield PC Card, Headers, Sips and IC socket, amp IC, resistors, capacitors antenna connector, documentation, Uno R3 operational software, and VAA.exe program.
Our completely assembled and tested unit costs $54.95 with all documentation and software.
Requires an Arduino or similar Uno R3, and an AD9850 module, supplied by the user.
New Special !!
Kits with AN9850 module.
I can now supply the kit with an AN9850 signal generator module. Cost for both $49.95. Only requires an Arduino R3 for operation.
Assembled unit with AN9850 signal generator module. Cost for both 69.95. Only requires an Arduino R3 for operation.
