80 m Vertical Antenna VNA Measurements vs 4Nec2 Modeling

E-mail Print PDF

I did some measurements on the vertical with my AIM4170 vector network analyzer in April. I also modeled the vertical with 4Nec2. There were some surprises on the resonance frequency and after some discussion on eham.net forum and model tuning I have got quite close to actual measurements. I may need to do something to the antenna as the resonance point is way too low. The measurement and modeling charts are at my antenna page: http://oh7ug.net/index.php?option=com_content&view=article&id=24&Itemid=4#Modeling_the_vertical
