DIY 5.8GHz Helical FPV Antennas VNA Test

DIY 5.8GHz Helical FPV Antennas VNA Test
I wanted to test how well my DIY FPV helical antennas are tuned .
It was pretty impressive to se the results ...!!
Thanks

Hello Sir.
Would you share the "plans" according to which you made the antennas? And how did you manage to match it so good (the immpedance) ?
Do you know what effect does the pitch (spacing between the turns) has on SWR and impedance ? I saw om calculators that with same number of turns/gain it would result in wider beam, but that seams like a "free lunch" and I know theres no such.

Looks Great Antennas mate 😊👍 Well done !

Thanks mate

Amazing results man. Can’t find you on the Facebook to text you directly. Are you in Australia as well?

I'm making a helical antenna too, and I'm wondering can you go too wide?
I have made a 5 turn coil with a copper wire 3mm thick. Is the thicness too much?

[@leonardterlevic4765]

I didn't have anything thinner

[@asangag]

Thickness of the wire does not affect the performance of the antenna that much. If you can bend the 3mm wire to get nice tight rings then i dont see a problem with using it

[@leonardterlevic4765]

Thank you for the quick response, I hame managed to bend a coil very close to specifications of another video and we'll see how it goes

What is the name of the measuring instrument?

[@asangag]

Its called VNA analyser
