Omnidirectional vs directional antennas what's the difference? | weBoost

[@MrIvan]

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.

[@qwrrye455]

Yes, I strongly agreed with you 🙏

[@ilyesnoname1959]

[@pushparajvaghela3476]

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.

[@00fke]

Aww, he seems like a great guy :(

[@ModiTheFox]

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

[@brookskeys8364]

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.

[@weboostsignal]

+Brooks Keys You're welcome, thanks for watching!

[@timepassvidio3623]

please... how produce radio wave in radio circuit

[@BillAnt]

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

[@TheMikevt]

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?

[@CaliforniaTravelVideos]

​@@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.

[@xforney]

I'm an computer engineer and understood cable and antennas, but not at the level that Don explained this subject. This is great learning.

Thank you for the clarity on how antennas work, have you done anything on the dish antenna works?

[@mscir]

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.

[@aamartins]

Excellent explanation! Thank you so much weBoost!

[@gerowen]

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?

[@paganphil100]

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 !

[@DY1SLAYZFR1]

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.

[@davidjames9935]

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.

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)?

[@paganphil100]

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".

[@steve4510]

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...

[@deek4290]

Can you explain more on effects of link quality in the directional antenna due to movements in a vehicle or something like that? ....Thanks a lot for great explanation.

[@weboostsignal]

+Deek You wouldn't want to use a directional antenna on a vehicle. Since a directional antenna will only send or receive the signal in the direction it is pointing, any movement such as moving a vehicle would reduce the effectiveness. You could use a directional antenna on an RV once it is stationary but you would have to re-position it each time you parked. An omnidirectional antenna is the best solution for vehicle applications. The same would go for if your antenna was mounted on your roof and got bumped and moved. The further the antenna points away from the signal source the worse it will get. Hope that answers your question.

[@deek4290]

+weBoost But for long range communication directional antennas would be appropriate ones.Long range communication like off-shore communication uses directional antennas.But the problem is that when ever the direction of the antenna changes the signal strength decreases.Is there any solution to this?Are there any mechanisms that can control the direction of the antenna?what parameters can be considered for this? Can you please answer ?

[@weboostsignal]

+Deek Correct, for long range a directional antenna would be the best. There are systems for this problem, they are complicated so I will not go into specifics. That being said, there are 2 types (1), uses electrical characteristics from multiple antennas to electrically tune in the strongest signal. (2) a device that monitors signal strength and then mechanically tunes (turn the antenna to track the strongest signal), the system for optimum signal strength. If you've got more questions we'd be happy to get into a more detailed discussion. Shoot me an email at [e-mail]
