- *** It is with sadness that we share that Don, the person featured in this video, passed away in December 2017. Don was a Navy veteran and a valued member of our product engineering team since 2004. He will be greatly missed.
Think you know your antennas? What's the difference between an omni antenna and a directional antenna? What's a Yagi antenna? And which antenna makes the best Wi-Fi antenna, or TV antenna or cell phone antenna?
Like most things, it depends on your situation. The guy with the answers is Don the Antenna Engineer from weBoost. In this 6-minute video he explains how directional antennas work and how they differ from omnidirectional antennas.
To learn more about signal boosters visit www.weboost.com/us/
We're here to answer all of those questions for you. Do you need an antenna for your car, truck or RV? Or is this an antenna for your home or business?
In short an omni antenna gathers signal from all around it so no matter where the cell tower is your antenna will find the signal and connect with it. A directional antenna captures signal only in the direction it is aimed. The directional antenna is stronger but you need to spend a little more time up front pointing it where the cell tower is located.
We go into more detail and explain the radiation patterns of each type of antenna, what radials are, and antenna design.
Feel free to leave us any questions you have in the comments.

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.
Yes, I strongly agreed with you 🙏
May he rest in peace
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.
Aww, he seems like a great guy :(
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.
+Brooks Keys You're welcome, thanks for watching!
please... how produce radio wave in radio circuit
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.
Wow! Not everyone is blessed with the ability to explain technical concepts like this. Thanks Don. R.I.P
Don, your video is probably the best understood video on how the antenna works on 30 or so videos that I watched on UA-cam. I am an engineer but not in this area, and your explanation is super clear!! Keep up the good work!!
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.
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.
I'm so sorry Don has passed. For what its worth I really appreciated this help.
I'm an computer engineer and understood cable and antennas, but not at the level that Don explained this subject. This is great learning.
You did a great job explaining EVERYTHING. Still helping people and leaving a legacy.
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.
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.
Abed Bod we're glad you liked the video and found it helpful!
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
This guy is brilliant, you should have been my antenna engineering lecturer back in the university, may you live a long life....!!!
Thanks for the kind message Willy!
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!
We're glad you found it helpful!
Thanks for watching!
This was one of the best video that explain it the way any one can understand.... good part is you are still spreading knowledge
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
I thoroughly enjoyed that. I have never taken a moment to even consider the workings of an antenna.
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!
Video was great! Very well-explained and easy to understand, especially to household users wanting to learn about antennas.
This is the best explanation I've ever heard.
Thank you so much for this great video.
So sorry to hear about the loss .I am sure he was an asset to your organization :)
I wish the internet was full of such elegant explanations.
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
Awesome work man, very helpful! You definitely know your stuff well.
Came here to like the great video, so sorry to learn of Don’s passing.
thank you so much! after many years I finally understand!
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
Thank you for watching Mounika!
Thank you weboost for keeping this informative video available . It is indeed a tribute to Don.
Best & simple description of antennas. Thank you
Thanks a lot sir ........I could not understand this concept in whole Semester, you just explained in less than 10 minutes
Thanks for watching Sainath! We're happy to help.
You're funny when you explain things which makes this discussion fun and interesting.
Glad you enjoyed, hope it helped you out! Thanks for watching!
Outstanding video. Sorry to hear of Don's passing.
awesome video thanks i learned a lot today. I'm installing a yagi on my folks home in alabama where its a dead zone. hopefully everything works out
Thank you for this video, now am a subscriber
you are indeed greatly missed 😩
thank you for your information on antennas. I am taking my CWNA exam in a few months and video like these are a great help on antennas
+Narresh Ramdayal You're welcome, thanks for the comment. Glad these were helpful to you.
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.?
Great stuff! You make it simple and very easy to learn. Keep up the great work!
We're happy you were able to learn from the video!
Thanks for watching!
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.
That was an excellent explanation of the difference of these two types. Thanks!
I am fortunate to learn from this video and the great sharing and explanation by you, Sir Don. Thank you for your sharing.
Thank you very much for those videos: You explain it very very clearly , it's appreciated. Thanks again. Helped me a lot !
He passed to a better place. This is the UA-cam I miss in 2022.
Now that is a thorough explanation. Can you please explain women on your next video. That would be very helpful as well.
Lol...Good one! Thats requires a much more technical explanation I'm afraid!
Too bad he passed away in 2017.
😂
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
@@BillAnt wait. What? The guy in the video?! V
Just plain excellent. Thank you Sir.
hi...thanks again you saved me years in testing...have a good time...
Thank you for the clarity on how antennas work, have you done anything on the dish antenna works?
Excellent explanation! Thank you so much weBoost!
Great series of videos.. Thanks for explaining the very complex subject in simple terms.
Thanks for the message Bradley, we're happy to help!
BeautifuL! You made your presentation very clear and easy to understand. Thank you.
Significantly educational! I'm grateful!
You just made it so simple. Thank you.
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.
thanks for the time you spent to teach on this subject. It has been useful in my understanding. Once again, thank you.
+707172gts You're welcome, thanks for watching.
Thanks for a great tutorial, can you please explain what is the best antenna for short wave radios?
Thank you for this initiative!
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.
Very clear and informative video. Well done!
Subscriber number 5000! Great videos, thank you!
Awesome!!! Thanks for subscribing!
Beautiful. Complex concept explained in simple way. RIP
Thanks for sharing such a lovely info sir....Its gonna be good for my Aircraft Avionics Radio system and aircraft antennas studies.....
I learned something today. Thank you.
Great Job you done Thank you so much Sir, i like to know that "Omni Antenna 5dbi" how long distance can support for open area?
I'm learning something new everyday thank you very much 4 explain to us ..
Explained it very well. Good video, I grew up using all types of antennas. I Have a Great FM set up.
Thank you for the excellent explination. Rest in peace. ♥
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...
Thanks for watching Syed! We will pass the kind message along to Don.
*Awesome sir, your explanation is GREAT!!! Thank you so much :)*
A very good explanation of antenna functionality, thank you
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.
Im a ham and i didn't quite know how a Yagi worked clearly this video was quite informational.
+Kelton Bailey Thanks Kelton, glad this was helpful.
Great lecture, will be watching more fr9m this channel
So easy to understand even for me who has a little knowledge about antennas
sir, your way of explanation is great
Thank you! Glad you enjoyed the video.
@@weboostsignal It's actually greater than great!
Best explanation I've seen, cheers mate.
Glad you enjoyed it! Thanks for the kind words.
Great tutorial, sorry for your loss.
Very nice video!!! very simple but very explanatory! Well done.
Thank you, glad it helped you out!
Thanks for watching.
very informative video!!! thumbs up
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.
LM m?
?!nnññ. nu ~~~
Very good explanation. Thank you 🌟
I have a question, what could you recommend for use to receive the best. I'm looking to use an antenna on my truck to pick up Mil-Air frequencies both VHF/UHF from planes. Thank you for the videos.
Great job: I am interested in reading up on step by step basics for first timer on this subject . Any suggestions .
great explanation and grafics, thanks!
Very concise, clear explanation of how antenna's work. Thanks!
+Brian Greul Thanks Brian, glad you found this helpful.
awesome video man !!!! thank you sooo much
you explain it very well. thank you
What the hell!!! This man is so good explaining things like this. (He was... I know). All the best to people who miss him.
=( yes he was realy good, sad to know we lost him...
He died? Whos going to answer my question?
Yes. He passed away.
Excellent information, very useful and easily explained Don!
+Alfonso Sotelo Thanks, We're glad it was helpful.
Excellent video, have a question about a 6dBi directional patch antenna's... Planning an outdoor marina solution, Cisco 9130AXE AP, beaming from an elevated position to cover the docks. In your experience what do you think the maximum effective coverage distance would be?
Thank you. Can an indoor antennae pick up a tv signal 100 miles away if a signal from a tv station is weak ? which one would work best
thankyou..you make it easy to understand..
very good animations in between the lecture.. this lecture is going to be help me in my project
question, I have a Omnidirectional Weboost antenna, my question is I put it on a 10 ft PVC pole above the Rv but was not thinking about the ground base that you talked about so does it have one built-in or should I have a metal plate below it or lower it to top of the RV ?
I have a summerhouse built out of a shipping container. Just ordered an omnidirectional antenna. I was wondering if when mounting should I isolate it from containers frame or not. Cause big metal box could interfere with signal?
Thanks for the clear explanation about antennas, one network provider in our area said my place is not yet serviceable for an installed broadband Fiber so I purchased a Prepaid Wifi LTE to the same Network Provider thinking it is better than their mobile LTE , but I can only get 1 to 2 mbps on the average download and upload speed even less, can I use a stronger antenna or will that result the same as my area is not LTE or broadband ready? Thanks
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 :)
Thank you for watching Gaurav!
super cool videos, very effective explanation!!! sad to hear about don, seems like a nice person
anyway to improve an omnidirectional antennas gain?
Such as on your car.
Thanks
Great presentation. I have a Huawei B525s SIM card router and cell tower is about 5km away direct line of sight, can you suggest aerial or booster to attach to router it can only be facing out window from inside.
thank you very much i have learned alot from these videos
