HackadayU: Introduction to Antenna Basics - Class 1

It just gets louder. A high gain antenna.

Excellent class! I learned a lot!

i like when you were talkin bout how "you woudn't think it would work" in space antennas ;).. FE..anyway basically you said, @31:ish"sometimes you just do what you need to do to make it work, so none of these equations matter at all sometimes"...right? lol i interpreted it like that because sometimes electrical stuff does some weird stuff.

Thank you for the knowledge. I've never learned electrical theories from a girl/woman before. I was pleasantly surprised! Hopefully more woman see this and get inspired. You make it seem easy, because it is, but not when you're first learning it!. You're a great teacher.I definitely learned (and relearned) every single second of this video, more learning than relearning. Thanks again!

There must be something wrong with me but I find antennas totally fascinating!!!!! Thanks for Sharing!!!!

Thank you for this video.

i'm samir from morroco, you're very good women

Sounds like too much reading of notes not engineering flow of someone with hardcore knowledge talk of antenna engineering. In my opinion of course.

Are those her pronouns?🙄

Glad you put the she/her next to your name otherwise I would have thought you were a man. /s

Thanks

What's the imperial unit for frequency, though?

Absolutely brillant : an extremely clear and pedagogic presentation. i finally understood a lot of things thanks to this class. i'll look forward to the rest.

Ah Smith Chart Work of Old times, now we have advanced Vector Network Analyzers, and Computer Software for anyone even an Electronic Engineering Technician can use to design antennas. Keep on Learning.

Great content but not great communicator....right?, right?, right?
Why do you keep saying that? Its clumsey and makes you sound like your unsure of yourself. Kind of a mismatch at what you know and your ability to communicate it.

Many Many Thanks

Poorly explained

Thanks for lecture 🎉

I didn't exactly understand how you engineer the different degrees of polarisation

how does this industry continue to be evolving despite the obvious biological harm, does money speak more to people in their jobs rather than the care for the environment and preservation / function of all life?

bad explained. unclear, not simple details facts and order

wavelength is horizontal, both antennas are vertical, the only way this would work is if the vertical amplitude is always equal to wavelength and this has always been my question which no video has answered, because the horizontal plane is time related.

Great Class

lousy. she is not well knowledgeable and not a good teacher either.

I sometimes get beat with a metal coat hanger. Will it also work as an antenna?

Right?

thanks for posting! very helpful.

thank you so much

I came here hoping to figure out how to hookup my antenna. These videos are so good that now, I only want to hookup with Karen😍 I’ll sort out all of this antenna techno-jargon and stuff later on... :P

Her constantly asking, "Right?" is annoying.

you mention 'YAGIE' ? would be nice isnyou explain what that is when you mention it. Also, as an engineer, i know we have tons of acronymns. in out circle we don't say them but expand the names: that is we'd say Voltqge Standing Wave, not "VSWR". acronyms are hand y when typing, but not talking, especially if teaching newbies. great course. look forward to the others, thanks very much

Hello. Do you upload your notes?

from u,i can see a lady not only beautiful but also knowledgeable

antenna is you distracting horney males with your existence

you disract me ya know, right?

Great explanation. Thanks 😊

I have no idea what people are complaining about, I didn't notice her saying "right" over and over, at all, seemed like a perfect delivery to me. Good tone of voice, patient, walks through the material just fine. I'm hoping to get into the weeds a bit on the next few classes.

If polarization only refers to the direction of movement of electric field E, then how is circular polarization possible? It shows two waves in red and blue. I thought we only care about the electric field wave.

I’ve landed here looking for information about how ancient buildings act as Antennas which I study for my work as an architect.

A common temple structure is an outer rectangle, mainly solid with an inner rectangle of columns. The column grid is also cubic. The columns are made from granite, under load from the weight above and so creating a piezo electric field around the column. The column structures are usually fractals of cosmic geometry such as the earth diameter which I guess would tune in to any waves emitted. I believe the earth is giving out a c# note.

Am I on the right track studying this? Is there such a thing as a cubic antenna grid. Any direction of what to learn would be great.

Your sound is great. I have made a few videos which have poor sound but they would never have been published had I worried about it. It is the content that matters. This is excellent content for someone at my level.

We need to talk about feedline and volocity factory ..

I am a technician..in RF and big radio operator

I watch all.i can ...

Thx for this very Helpful video.....The "Ole Boys Club" can't stand it to be outdone by your superior delivery combination of witt & making the student feel very comfortable trying to absorb the very complex engineering principles.....

I think this could be a very good and educational video, if the lecturer would stop repeating the word RIGHT, so often, as is I can’t finish the video.

Thanks for the course! An omni directional antenna has a gain of 0 dBi. Using dB values in beneficial when calculating link budgets, because you can add and substract instead of multiply and divide.
