Hi All,
To those who are seriously interested in VHF/UHF antenna measurements I recommend the VHF/UHF Vector Impedance Analyzer model T100+ made by Timestechnology.com.hk and sold as new via Ebay at US $ 249,00 ( about Euro 194,91)
I hown one of this and I am very satisfied with it's VHF/UHF accuracy.
The manufacturer Timestechnology.com.hk sell the T100+ only via Ebay
Belove you will find the links for characteristics of the instrument,the user manual and will look at the diagrams on display but Google is full of informations only to write on it T100+Vector Impedance Analyzer.

In VHF(100-170 MHz) and UHF (400-470 MHz ) the T100+ is more accurate than the model MFJ-269
Following my calibration and comparison against professional Network Analyzers the MFJ-269 accuracy is good at most up to 30 MHz.
