FA-VA5 600MHz Vector Antenna Analyzer Kit
A high precision 600 MHz Antenna Analyzer for measurements of antennas, cables and other one port devices.
The VA5 is a portable, full-featured Vector Measuring Device with a frequency range of 10 kHz to 600 MHz, with the added benefit of a USB port for connection to a computer.
Now introduced due to customer demand - a 99% Assembled and Tested Kit!
designer, Michael Knitter DG5MK, has taken feedback from users of the
previous VA4 instrument and incorporated many of the requested new
features in the VA5, whilst maintaining high performance and excellent
value for money.
Frequency Range 10 kHz - 600 MHz
Small dimensions 15 x 8.5 x 2.2 cm - fully portable
User friendly - intuitive menus
Large display with good readability
Low power consumption (up to 40 hours from 2 AA batteries)
SOL Calibration function
USB-interface with support of the DG8SAQ VNWA Software
Real time clock with backup capacitor
Audible buzzer alert for minimum SWR alignment
The FA-VA5's graphic display shows the complex impedance, standing wave ratio, complex reflection coefficient, capacitance and inductance.
Vectorial measurement means that, unlike a scalar instrument, not only the SWR is measured and displayed, but also the value of the impedance, including the signed imaginary part. The so-called SOL (Short, Open and Load) compensation is used for the calibration of the device and provides precise measurements in different configurations.
FA-VA5 Technical Datasheet
New Feature - USB-interface
The new USB-interface allows follow-on processing of measurement data, a feature that was top of the wish list for many Radio Amateurs. Michael has collaborated with Dr. Thomas Baier, DG8SAQ, to introduce support for the VA5 in his well-respected DG8SAQ VNWA software application. The combination of FA-VA5 and VNWA Software will allow all kinds of one port measurements included in the software. One example is Time Domain Reflectometry (TDR) to help find defects in antenna installations. Ths USB-interface also enables the user to carry out future firmware updates to the VA5.
Available either as a complete Self-Assembly Kit, or a 99% Assembled and Tested Kit.
Both Kits also include Short, Open and Load calibration elements, which are usable up to about 100 MHz.
A high-quality 3pc or 4pc calibration kit, covering a frequency range up to 600 MHz, and with Load parameters individually measured, is also available from our Webshop.

99% Assembled and Tested FA-VA5 Kit
To complete the 99% assembled FA-VA5 kit only needs the On/Off Power switch to be soldered to the Main PCB and the ready assembled LCD/Backlight module to be plugged in before fitting in the PCB into the enclosure. Typically this should take about 10 to 15 minutes.
Complete Self-Assembly Kit
The FA-VA5 is available as as a complete kit including a pre-assembled PCB with pre-programmed microcontroller, graphic display including backlight, and a
USB module, fitted in a specially designed enclosure.
The kit also includes Short, Open and Load calibration elements, which are
usable up to about 100 MHz. A high-quality 3pc or 4pc calibration kit, covering a
frequency range up to 600 MHz, and with Load parameters individually measured, is also available from our Webshop.
Final assembly of the kit is considered to be of medium difficulty and consists of fitting and soldering just 12 through-hole components which should take under 3 hours.
