So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 ) 🔵 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 ) 🔴 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 ) 🔵 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 ) ⚠️ Quran

Basic Basic Knowledge for Americans stuck in England where Antennas are what Insects have extending from their heads - so Antennas get called Ariels instead whilst Broadcast Towers often get separately labelled as Mobile Phone Masts ( which are very unpopular in spite of nearly everyone under 70 using one regularly ) - and TV & Radio Transmitters which generally go unnoticed or ignored as mere things on hill tops ‘in the middle of nowhere ‘ (unless you enjoy fantastic views or are an “ Anorak “ - a sub genre of Geek or Nerd whom photographs them - and Trains , but which are essential for all old fashioned folk that lack Sky tv but have intellect ) Hope this helps as well as the presentation does 😁👍

Which TV antenna is the best?

[@vitobellezza]

Actually, the Yagi antenna was not invented by a man named Yagi but by a man named Uda. Mr. Yagi filed the patent on behalf of mr Uda but put his name on it.

[@jamesk0ua]

AND that antenna identified as a Yagi was not a Yagi. It was a Log Periodic. At least the back half was. The forward part is a type of Yagi, sort of. with a parabolic corner reflector... but I digress.

[@genesky61]

Truth and Quality Practical and Useful Information. ---------------------------------------------------------------------------- Many Humans are Crazy for the word Yagi. They think all antennas are Yagi. The Truth is , True Yagi antennas are very narrow band width antennas not real suitable for wide band with Tv reception. The Truth is a better antenna for reception across a wide band width such as and not limited to Tv channels is Log Periodic Antenna. Even so , many antennas and not all antennas are made up of 2 sections , Log Periodic at the back of the antenna for the VHF Tv channels. ------ Front of the antenna , A Modified Yagi , for the UHF Tv channels. A Modified Yagi is not a true Yagi. That is the Truth. If you will go deeper in to the subject , many books and internet information.

[@LightGuardian-ed8zl]

[@cyrusIIIII]

What in Antenna affects the frequency that it can receive? Is that geometry? type of material? size?

[@SolidSignalNovi]

It's the size of the antenna as a fraction of the wavelength.

[@charlesbrightman4237]

Along those lines, with the increased cosmic radiation that is going to impact this Earth this century: "Batteryless Battery"???? a. Small aluminum cones with an electrical wire running through the center of the cones, cones spaced apart (not touching I'm thinking) but end to end. b. Electromagnetic radiation energy in the atmosphere interacts with the aluminum cones. c. Jostled atoms and molecules in the cone eventually have some electrons try to get away from other electrons of which those electrons gather at the larger end of the cone, of which also creates an area of positive charge at the smaller end of the cone. d. The electron's in the wire are attracted to the positive end of the cone and the positive 'end' in the wire are attracted to the negatively charged end of the cone. e. Basically a 'battery' has been created inside the electrical wire itself, different areas of electrical potential. Basically a 'wire battery' or a 'batteryless battery', however one wanted to call it. f. Numerous cones placed end to end increases the number of 'batteries' in the wire. Then of course, one could take that generated dc electricity to split H2O into H2 and O2 of which could be burned or utilized in a hydrogen fuel cell to get the electricity back with a byproduct of basically pure water. Species need pure water too. With the increased cosmic radiation that is going to be impacting this Earth this century as well as possibly a mini-ice age, might as well put that cosmic radiation to work for us.

[@zazugee]

just the explanation of the Yagi actually don't apply for the standard yagi, it was made that way, so that the directors elements interfer with the waves in such a way that it cancels waves that are at a large angle and make the whole antenna directive, and higher gain the modern yagi antenna re actuall a mix of a yagi and a log periodic antenna or a mix of 2 different yagi antennas disigned for different frequencies bands

[@ooDriveoo]

uhm the tower does not radiate, the antennas mounted on the tower do.

[@todkapuz]

well unless we are talking about AM radio, then yes the tower itself IS the antenna, as optimal length of the radiating element is approaching 75 meters / 250 feet. Do s search for "mast radiator" or "radiating tower". And often, you will find several seemingly the same sized towers in a row with nearly equal spacing... you are actually seeing a directional (gain) antenna for low frequencies... if its two then a phased array, if more then effectively a yagi antenna (see "tower array"). Sometimes you will see a grid of 4 or 9 antennas in a square that are shorter and your looking at a direction finding array for aircraft.

[@SP-mp9yi]

One question that's driving me nuts: If I double the antenna size will I double or improve the gain ?

[@SP-mp9yi]

DX Commander agh I think I follow thats a great start thank you, so the size of the antenna is specific to what your trying to capture and it cant be changed. I’m trying to get a cell phone signal at a remote property in the 700mhz region and the best I’ve seen is a 16 gain Yagi from ZDA, my thought was to just use a giant TV Yagi, so is it possible to use multiple of the specific size to try and capture more of the specific signal and then try to connect it to one feed ?

[@SolidSignalNovi]

@@SP-mp9yi @dx commander is right.

[@SP-mp9yi]

Solid Signal So am I right to say each frequency has a maximum antenna size ? One other question guys do antennas catch signal only so they amplify what is already there or can they also fetch signal ? What I mean by that is if I point the antenna at a area that has good reception but not a tower that doesn’t reach my zone can it connect a path back ? Oppose to having to direct the antenna at a tower that may be out of site ? Back to the question of maximum size if I needed more gain from the possible signal would I be able to do it by doubling the maximum size antennas so having 2 4 or even 6 of them going into one feed ? More antennas not bigger ones going into the feed ?

[@SolidSignalNovi]

S P antennas are passive. They can only receive what is coming at them. You can combine multiple antennas for more gain but you only net about 2dB from the second antenna.

[@SP-mp9yi]

Solid Signal Super Fantastic Thank you very much. I actually rewatched your video and things sank in a lot further the 3 time, if the signal is not at the location no array of antennas will help and multiple of the right sizes gives about 2 gain not the full 16. So my only test left will be to try and install the 16dbi Yagi’s in front of old satellite dishes at a 45 degree angle to try and match the cell towers waves. If that fails I will initiate plan G move to the city. Thanks again and happy thanksgiving.

[@SkyhawkSteve]

The statement "a loop antenna is a type of dipole antenna" is not supported by anything I've seen elsewhere. A loop antenna senses the magnetic portion of the electromagnetic field, while the dipole senses the electric field.

to follow up to my comment, the next page of the antenna theory site discusses small loop antennas, and makes the point that it utilizes primarily the magnetic field.

[@sridharchitta7321]

What is radiation? How is a transverse wave produced? What is refraction? Light is an electromagnetic wave comprising electric and magnetic field pulsations or variations in strength at each point in the space. It is a form of radiated waves of pulsating electric and magnetic fields. They are produced by accelerated electric charge which produce a transverse electric field which propagates outward from the accelerated charge. The radiated fields constitute a wave travelling through space. The fields don't travel, the wave does. Yhe fields pulsate in strength. This is best visualised by a rope, one end of which is fixed to a wall and the loose end held some distance away. The loose end when moved up and down creates a wave travelling. Notice how the molecules of the rope near the wall have not travelled to the loose end. The snake-like shape in the form of a sinewave and travelling movement you see is the overall effect of the up and down movement of the molecules of the rope. The same happens with the strength of electric and magnetic fields of radio waves and light. There are no sinewaves in space! It is the strength of the electric field say, which we plot of a radio wave which has a pattern of a sinewave. When a radio wave or rather the fields of the wave encounter matter, they set into motion the atoms in the material. The acceleration they produce of the charges that make up the atoms and molecules in matter, produce electromagnetic waves and these are reradiated fields. The incident and reradiated fields combine to produce a resultant wave. These resultant waves constitute the fields in reflection and refraction. Watch the following videos to get an idea of radiation by an accelerated charge and an oscillating charge.

Then why would a dish not be better than a yagi to pick up UHF?

[@SolidSignalNovi]

It would, but then you would only be able to focus on a very small area, and it would have to be a very large dish to deal with the larger VHF waves.

[@RickPaquin]

@Fact Checker Antennas similar to the 4251 are STILL made today for cable head end systems. They are huge and I'm quite sure VERY expensive, and they would require a heavy duty tower.

[@todkapuz]

eeehhhh? I mean I get your doing this for a technically illteriate crowd, but some of this stuff is a bit far off base. For example a true yagi absoultely is about the interaction of the elements at a close proximity. THe antenna your showing is a hybrid of a few but mostly a log-periodic.... but anyhow... and then the whole thing about distance and digital... the signal itself is exactly the same as analogue and works exactly the same way, the only difference is error correction in digital means it produces a visual image that is shapr until the point that the signal-to-noise ratio introduces too many errors into the decoder. This has nothing to do with antennas (well I mean yes, if you have a more directional, aka higher gain, antenna then yes you can pull more signal, but exactly the same amount of signal as analog). Monopole is not JUST a telescopic antenna, and its wrong to say as such. And no antenna is rated by the distance it will receive. The distance it will receive is a function of the transmitted power, the frequency, height above the ground of transmitter and receiver antennas, the gain of transmitter and reciver antennas, and then any propogration effects (not significant in tv, but very significant in AM broadcast).

This actually a poor explanation. The examples given are too simplified and misleading. I take particular umbrage at the 'Yagi' explanation. This is not how a Yagi works at all, what he is showing is a multi-band TV antenna and he explains how the bands are separated not how a Yagi actually works. This video is aimed at a consumer level and should not be used for any serious understanding of antenna theory as many concepts are flawed in order to keep it short.
