Even though you passed away you are still spreading knowledge, thank you. It's crazy how easily you explained that, I've been working with antennas as a hobby for a while and had no idea about a bunch of things you cleared up in this video. Sad to read the description of the video and learning from your passing away.
Can you tell how much the size of patterns differs b/w the two comparable (omni vs directional) units from same manufacturer. Basically how much the gain is.
Rest in peace Don, an invaluable addition to the endless sea of electrical and radio experts that specifically Don set a shining example of what to strive to be Thanks for your immensely appreciated work with Wilson/weBoost and the field of radio communications
I'm an engineer, but not an electrical engineer. I have NEVER been able to determine how, what appears to be a single wire, is able to relay a radio wave into the radio. This video and "How does an antenna work" explain this very clearly. Thanks to Don Dinsdale and WeBoost for these, and the other, videos.
It actually uses Don's unbuttoned cuffs to direct the radio energy forward. xD Oh, at 2:09 that "thing" looks like a penis antenna, but the main thing is that it works! lol
What is the mathematical equation for the branches. I know it works in a magnetic flux field. Is it possible to move the branches to optimize the signal? Say when you increase the size of the antenna?
@@TheMikevt First off, the wave LENGTH of the signal is the reciprocal of the center frequency, sometimes expresses in lambda (velocity/frequency). In the design of a Yagi, the basic "zero-order" type has all of the radiating elements (smaller directing antennas in front of the reflector) designed to be one-half wavelength long and spaced one-quarter wavelength apart from one another. From here the calculations for the spacing and number of radiators gets more complicated but the principle relating to generate a stronger antenna gain that is more directional with different impedance, side-lobe characteristics, etc. still relates to the mathematical relationship of the radiators. Bottom line, both the length and spacing/distance is important to ensure the directors generate additive signal strength, just like the prism reflectors in a lighthouse.
DIY guy here (goldsmith/master jeweler, photovoltaic/solar thermal technician) made lot's of antennas without having the knowledge of why and how they work. really appreciate this video
Rest in peace Don, i am watching your video all the way from the UK, London learning about Antennas, this video has helped me greatly. Thank you. My condolences and prayers.
Don, your video is probably the best understood video on how the antenna works on 30 or so videos that I watched on RUclips. I am an engineer but not in this area, and your explanation is super clear!! Keep up the good work!!
I checked all the videos made by those so - called Engineers and Dr, but never get what they were talking about, till I bumped into your videos. Thank you very much for this outstanding video.
Apparently he passed away in 2017... a woman killed him. lol Trust me, after 20 years of marriage, they'll just clean you out of your last penny, so the closest explanation is "Men are from Mars, women are from Venus" 'nuff said! xD
I am looking to boost my cell service where service is weak at home. I stumbled on this video and appreciate the explanation to a lay person. Sorry to hear about your loss. I would like to thank Don for his service and WeBoost for your assistance with this video.
One of the best explications out there, everything is so clear ! Thanks ! Just seen the RIP comments… So how could i not join ? RIP Don, I'm sure you helped so much people, deserve a great rest now.
Wow, this video and the one about dipoles made the subject so clear--thanks! I could watch your videos all day. Much appreciated. You've removed the mystery of antenna construction and increased my curiosity. Neat stuff!
EXCELLENT, Sir. Very simple explanations, yet, as how you explained the subject matter, how truthful. Sir, I had never understood the yagi antennas of days gone by for our tv sets, until now --> sixty-five (65) years later! Thank you Sir, very much indeed. Great video too. Oscar
You are a genius Sir, I am a student of Msc Electronics in University of Kashmir. I really liked the way u make it understandable in a real sense which is actually the purpose of Study... Here teachers make it only upto the mathematical calculations...
Hello Sir/Weboost, Thank you for your concise yet highly effective explanation of the Antenna working concept. Despite going through various videos and documents, your video stood out in making the concept crystal clear for me. All my doubts have been resolved, and now I grasp the antenna's working mechanism much better. Your help is greatly appreciated!
Sir really have a awesome experience in the field of antennas,and your work in this video is really meticulous.You have made my doubts pretty clear.Nice videos
You should research Japanese scientist name Yagi in how he discovered the yagi ant and how it works. This fella you said is not correct on a yagi ant. builder.
Interesting, thank you. I'd like to see a more detailed yagi analysis. I was told by a ham operator that the directors absorb then re-radiate the energy, and that's how they increase signal strength, so I think I see how they make the signal more directional but not how they increase gain. If you did a more detailed explanation showing what happens at each element of the antenna that wold be very interesting. Thank You.
Your videos are amazing. Brief, to the point, interesting .. i watched a ton of ham radio videos but really did not understand antennas till I watched yours. Thanks
Your teaching technique is outstanding. I have learned a lot. If you get time can you explain how a single dangling wire on an electrical garage door works. As well, could you include how the coiled wire around a tube inside the remote works. Again, thank you so much for your gift of teaching about antenna's.
What I like about directional Antenna’s is I can receive more clear signals because it’s not receiving signals on the sides and rear of the antenna like static frequencies. Having a omnidirectional will receive all the static frequency’s or whatever you call it. I’ve experienced this with my home base having to have a switchboard and a huge improvement especially tracking a mobile car. Hoping to have your input about this great video though.
Great info ! Clear explanations and just the right amount of detail. Really like the use of graphics, clear audio with background, and edit length of clips. Having done production and editing for advertising and educational video I might make a few suggestions to polish the look and presentation. I will have a look at a few more videos first and won't presume to add my opinion here. Looking forward to using some of your gear for ham radio applications.
+Chad Pennington Hi Chad, thanks for the input, we appreciate it. Glad these videos have been helpful. We welcome comments and suggestions as we are constantly striving to make our videos better. Feel free to email us at socialsupport@weboost.com with your thoughts. We'd love to hear them.
I really like how you break stuff down so that someone can really understand what you are trying to explain you really know how to show a person how it works im going to subscribe to your blog you are really good at what you're saying and doing keep up the good work. Tyrone Baltimore Maryland Happy Holidays to you and your family. Plus keep up the good work.?
It is probably a good idea to state that directional antennas will radiate in ALL directions, just not well. For example, if you made a Yagi antenna with 50 elements, it would likely have very good forward gain but you could walk around the antenna with a field strength meter and likely get some deflection of it assuming in the favored direction it was calibrated for full scale deflection. It should be stated that even a directional antenna will have good enough performance near it. Especially if it is a casually fed array in which the nulls will no be so good. Also, any omni antenna can likely be turned into a directional antenna by doing any of multiple things to it such as putting a dish behind it to focus it, creating a phased array or verticals.... So in the case of phased verticals (let's say 2 identical verticals), each antenna then is NOT omnidirectional cuz a main lobe will form . You likely already know this but I am just stating some exceptions where you are stating the general rule. Lastly, I wonder why they say when phasing 2 or more antennas that they ideally have to be identical antennas. What would happen if I took 2 same band antennas but were physically different? I would assume if fed properly they would still have gain. For example, if I had a 5 element Yagi and stacked it with a 7 element Yagi. I put the 7 element lower to help reduce the wind load on the mast and put the 5 element higher since it has less wind load. I wonder if something like that can be modeled correctly using antenna modelling software.
Hey!! Don, you are really nice and you teach very well!!.. i liked your way to make things understand!! and those who dislike this they don't have an appetite to learn!!. Keep Rocking we boost and Don :)
first, thank you for your video how does the electromagnetic wave of antenna travel through all medium without affected by all conditions of environment like( rain ,or faced high building in their way)?
Gehad Ali: The EM wave IS affected by obstacles (buildings, trees, hills etc). The higher the frequency, the more it is affected which is why WiFi and cell-phones which both operate on extremely high frequencies would have a very short range if they didn't use relay-towers or "boosters".
Comparing relatively the same power and brand antennas (Omnidirectional vs directional), how much distance (in feet) is gained or lost (looking at the source of intended hookup/contact, ball-park estimate of course)? Example: a directional antenna can reach out further to the intended/hookup source vs an Omini antenna that spreads out its energy around the antenna… Therefore spreading out the energy will lessen the distance to the intended source...
On those whips are the spring/coiled portions of the whip there to act as a choke and reduce the amount of reflected power that makes it back to the radio, or are they there to act as an actual spring/strain relief mechanism?
Marcus Adams: The coils are usually used to reduce the PHYSICAL length of an antenna whilst still retaining the ELECTRICAL length. If they didn't do this you would have to have very long unwieldy antennas on your car !
Excellent videos Don, really well explained, the graphics clearly simulate the theory, I have question ? ... what are the carrier frequencies to enable a signal to become airborne, ie the signal escapes from the wire/aerial and then can't get back on ...? Somewhere starting at the Long Wave Low frequency range... Google claims its 30 - 300 KHz.
Sir, can you create a tutorial on how to create an attenna for TV just by using homemade tools, like wires, coppers, and any metal that can be found from the kitchen? and also antenna to boost cellphone internet if possible?
So it's like transformer coil wired next to each other. The magnetic field flux lines don't cross each other so they slightly change the direction of magnetic flux lines combining with each other making sort of longitude (directional) magnetic field.
Even though you passed away you are still spreading knowledge, thank you. It's crazy how easily you explained that, I've been working with antennas as a hobby for a while and had no idea about a bunch of things you cleared up in this video.

Can you tell how much the size of patterns differs b/w the two comparable (omni vs directional) units from same manufacturer.
Basically how much the gain is.
