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]

May he rest in peace

[@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.

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.

[@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.

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?

[@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 !

[@gehadali3597]

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".

[@chadjones99]

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 ?

[@nashly0219]

Can i ask a question directional antenna works in remote area right? How far the direction antenna to the tower in maximum.

[@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.

[@withage]

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.

[@davidjames9935]

Here is another question for Mr. Don Disdale. Suppose I had 4 identical 3 element beams such that each had a half power beamwidth (HPBW = -3dB downpoint from max forward gain) of about 100 degrees and they were aimed in the 4 major map directions (N, E, S, W) and properly fed thru a proper (narrowbanded) 4 way splitter/combiner for the intended frequency. Also assume that each beam is rated at 8 dBi solo. My question is would this setup (if done properly) have more gain than a single 8 dBi omni antenna? You can assume very low loss cables and a very low loss power divider/combiner. Reason I ask this question is because many ham radio repeaters use a vertical stack "omni" but it is "shadowed" on one side by the tower so I am wondering if for that same application, it would instead be better to use 4 short Yagis pointed in the 4 major map directions. You can assume that each one would be mounted on one leg of the tower. For 3 sided towers assume we use only 3 beam antennas with slightly wider HPBW (say 120 degrees each).

[@weboostsignal]

+David James Short answer, no. Just the loss in the splitter and cable will negate this. Also remember that a Yagi will only see one cell tower. So an array of Yagis (unless you are looking for different cell towers at the same time) is not practical. The "shadowed" effect would be minimal, maybe 2dB, depending on the width of the tower. If you need omni performance, a Yagi array will work, but not recommended, just cost is prohibitive.

[@davidjames9935]

+weBoost Well first off I was not referring to cell tower as I mentioned ham radio repeater tower in my question. Secondly, if the 8dBi gain is retained overall, then the 4 beam setup could be used to transmit equally well in all 4 map directions but a sophisticated "voter" system could be used for reception to best hear a moving target such as a mobile station. That way as the person drives, the voter system would select the best of 4 antennas to use to receive him clearly. Since the receive would be better than the transmit in the direction of the mobile station accessing it, the repeater could compensate by running significantly more RF power than a typical mobile station so both receive and transmit are better "balanced".

[@jorgeventuragarcia9275]

which interior antenna works best for an area approximately 2000SqFt

[@GlenKowalchuk]

Great, so to achieve optimized LTE speeds we now need a MiMo antenna. What WeBoost amp has dual inputs for MiMo antenna?

[@babarumraisin4863]

I'm using a SureCall Omni exterior ant. with my Weboost drive 4G-X on my RV, which is aluminum. I get no apparent cell boost. Do I need a metal (steel) plate under the SureCall for it to work properly?

[@Aerospaceman]

The antenna seems to act like an inductor whereas you input current and get a magnetic field. So, the current flows in both direction and cancels out until you bend the wire, does this create a plane? The electromagnetic field being transmitted is the frontal lobe? with very small back scatter and side lobes?

[@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...
