miniVNA antenna analyzer V224
Reference manual for mRS antenna analyser type miniVNA 0.1-180 MHz
The device is designed to measure antenna impedance and filters over the HF and VHF frequency range.
The small hardware (9x5.5x3cm) uses an USB connection to a PC where the antenna parameters can be
displayed, one full scan takes about 0.5 sec per 500 samples, the instrument will give a big help to tune and
design antennas especially for radio amateurs.
The original software runs under Windows PC, by the way many hams worked on different version such as
DOS, LINUX and PDA with Windows CE (Windows Mobile 2002-2003).
Several Hams have actively contributed to the development and supported the project in different ways, I
would like to thanks in particular Juan Carlos(
nominativo
), Stewart G3RXQ, Peter PA0PDW and all other
hams very active in the discussion group at

System requirements
•
PC with cpu 500Mhz or better, WIN98, WIN2000, XP or LINUX are supported
•
The device work also with pocket PC, WIN CE are supported.
Before you start
•
Do not expose this device at strong rf fields (expecially with antenna connected), may be cause
permanent damage of internal detector.
•
In case of battery supply (not USB use) do not excede 5VDC.
•
In antenna analisys this device generate about 1mW from 1 to 180 Mhz: it may cause interference
and local QRM to others HAM radio station.
