Impedance of the antenna has both real and imaginary parts. Real part is the resistance while imaginary parts are the reactances. Reactances can be either inductive or capacitive.

Odd harmonic resonances of 80m dipole antenna, center fed and mounted in inverted V configuration, being checked by a NanoVNA. Third harmonic, fifth harmonic and seventh harmonic near

Moxon Yagi for LEO satellite operations has elements for VHF and UHF, but only a single feedpoint. Driven element and Reflector are Moxon VHF elements. Driven element is

I have used my HF Fan Dipole for VHF/UHF Satellite Communication successfully a few times! Checking resonance with NanoVNA on those bands to see how the very high

I am trying to use Ham Radio Antenna for FM Radio as I already have it installed outdoors! Multi-band inverted V fan dipole antenna has its apex at

Here is a $3 FM Radio Board with Remote, Bluetooth and More! It has provision for MP3, USB port and auxiliary input. This video covers the initial assembly

See the four resonant points of multi-band fan dipole antenna on NanoVNA! They are for 40, 20, 15 and 10m amateur radio bands. The antenna has elements only

Checking SWR of CP22E antenna with NanoVNA on VHF and UHF, to see how the VHF antenna works on UHF as third harmonic. That is because I have

I have been trying to figure out SWR measurement with the new NanoVNA! Here it is, SWR measurement of my half wave dipole 80m antenna.

It is always nice to have verification of calibration on NanoVNA. Method of verifying calibration is detailed here. From the menu, select display and activate the Smith chart
