Homebrew VNA (Antenna analyzer)

Postby Eamon » Thu Jun 02, 2011 3:03 pm

Here is a standalone adaptation of the N2PK vector network analyzer


Schematic, artwork and firmware are published.

It is based on the original design by N2PK which you can read about here

It only covers HF, but it compares very favorably with other VNAs. Here http://www.m0wwa.co.uk/pdf/VNA_comparisons.pdf are comparison test results of a several commercial ham-grade analyzers along with the N2PK design and a HP 3577A.
