Analyzing My Homemade Antenna With The Nano VNA

[@iowahank1]

Thanks for the 20 mtr FT-8 contact today Paul. You're antenna is working 😁

[@learnelectronics]

Great!

Let's see this clever device being used in a school room setting such as breadboarding a simple one transistor AM radio and then hand winding a few turns of copper wire around an ink pen body to form an antenna. Then measure that antenna. Show how pulling the coils apart might or might not effect tuning. Show how an extra turn or one less turn effects tuning. You could also demonstrate how to adjust the tuning screw on the base of cheap CB radio antennas can be used to fine tune them for a particular car receiver. I'm guessing you could mount your collapsible antenna to this device to demonstrate range of that breadboard AM transmitter?

Paul, what is the total length of the coax?

[@learnelectronics]

75ft

M7MUK hope to catch you on air.

KF5AQF - not on often now - have to get back into it. Maybe with video's like this here I will be encouraged!

I found it critical to calibrate with any cables in place to the DUT. Thats why they include a barrel connector. The upside is the VNA sma connectors are not getting stressed.

Rf is pure magic, unknowing for us mere mortals.

[@radiotests]

I trust you included a 1:1 current choke at the junction. It also matters if you tested after the feedline. The feedline is more of a dummy load flattening the SWR. The best test is signal reports and checking your output with remote SDR to hear your signal firsthand.

Enjoyed the video. Thanks for sharing

Are you sure the wires are 8 ft 6 surely that will give a dipole for nearer the 10m band?

[@learnelectronics]

Positive

Great little vna for around $100👍 The guitar picks are genius lol

[@jasonvictor9542]

Great video, i',m going to use my Nano VNA for my HF antenna tunning, thanks man!

[@learnelectronics]

Have fun!

[@bblod4896]

Snow! ☮️ brother.

[@bblod4896]

I'll analyze my dipole and send you the results. 😊

[@ImnotChuck.]

Do you give out your call on KZbin; if so, please post it here. Thanks and 73 de KJ4FX.

[@sumolee1761]

I talk on 11 meter

[@warplanner8852]

I feel very sorry for you.

[@radiotests]

They have vaccinations for that STD.

[@Jimwill01]

CB radio??

[@sumolee1761]

I know right

[@86jekstrom]

They're mad because they can't touch us bowl operators🤣🤣🔨
