A high-gain antenna HGA is an antenna with a narrow radio beam that is used to increase signal strength. High-gain antennas provide a more precise way of targeting radio signals and are therefore very essential to long-range wireless networks.

Hence, 7. In general, the higher you place your antenna, the better.

It would be best to have your antenna placed 30 feet above ground level to give you the clearest over-the-air connection with a tower. For those looking for that height, outdoor antennas are usually a good place to start.

With this 5dBi antenna, theoretically a distance of about meters can be covered. There are several different types of antennas in three broad categories: omni-directional, directional, and semi-directional.

Antenna Gain for Dummies. Typically measured in decibels relative to an isotropic radiator dBi or decibels relative to a dipole radiator dBd. Since an antenna does not make power, increasing gain in one direction will decrease propagation in another. It is defined as the ratio of the induced voltage to the incident field. Wrap your TV antenna in tin foil.

Wrapping aluminum foil around your antenna will basically increase the surface area and conductivity of the antenna to boost the signal that your TV receives from it. Does grounding the antenna improve the TV reception? Answer: It some rare case it may help the reception a little but usually it does not. The purpose of grounding the TV antenna system is mainly for user safety.

Grounding will help reduce the damage and the chance for fire if the TV antenna were struck by lightning. If this is not the case, the reason could be one of the following: There is not a clear line of sight to the broadcast towers.


To aim all of our antennas, face the front of the antenna in the direction the channels are broadcast from. It will show you the compass orientation and direction the channels are broadcast from. Any time a TV distribution signal is split, it will encounter insertion loss that will weaken the signals distributed beyond the splitter. This is typically measured in dB. Skip to content.

Get to Know Us.The fact that their house was surrounded by hilly terrain, as well as being located 70 to miles from most of the local transmitters, dictated the need for a high-gain, long range antenna capable of picking up signals over that distance.

So they came to me I'm an electrical engineer and asked whether they could build an antenna that would serve the same purpose.

By this time, I was excited enough to jump right in and give them a hand, so I drew up a plan, and we built the antenna — twice! The first model, you see, was destroyed in a storm, so I took the opportunity to try out some new ideas on a second version — a conduit and plastic-pipe model. The one I'm about to describe incorporates the best features of both these prototypes. Any antenna — TV, radio, or whatever — consists of three parts: the element array, the framework, and the mast.

From a performance standpoint the element array is the most important because it picks up the signals, but it's actually nothing more than a metal pattern of the right size and shape to suit a specific purpose. This design uses a Yagi-enhanced, log-periodic pattern —which, simply put, means that it has broadband capability and can thus cover the very high frequency VHF, channelsultrahigh frequency UHF, channelsand frequency modulation FM broadcast bands. Commercial elements are usually made of aluminum rod, sometimes anodized to resist corrosion.

However, we got by with bare copper-stranded "radio" wire and some insulated bell wire left over from another project. The framework is nearly as important as the element array because it supports that pattern and holds it in shape. Our bamboo cost us nothing and was both strong and lightweight; the parts for the PVC-pipe and conduit frame unit had to be purchased, but it was a bit easier to assemble than the "cane" version.

Actually, anything light and rigid should work, but it would be better to choose a nonconductive material to avoid interfering with the pattern. Finally, the mast holds the entire antenna assembly above the roof and parallel to the ground. We used a 10' length of 1" conduit electrical metallic tubing, or EMT for short to do the job, but any kind of thin-wall mechanical tubing would serve as well. Often, depending upon one's geographical location, a fourth component — a rotor — can come in mighty handy for aiming the antenna directly toward different transmitting stations.

Sounds easy enough, doesn't it? Well, bear with me and I'll walk you through the construction procedure step by step.

To start, you'll want to rough out the framework. If you do have access to bamboo, feel free to use it — but be sure to dry and varnish about twice as many stalks as you think you'll need, because it's brittle and prone to split when being cut or drilled.

The idea is to make a trellis affair like the one shown in our Antenna Diagram. Then move to the opposite end of the poles and bolt them to the 8' PVC section, keeping the distance between the tips equal.

Next, measure 42" from the front of the frame and mark a mounting location for the 40" piece of EMT, then measure 43" back from this point and do likewise for the remaining 6' section. Trim the conduit pieces if necessary, and drill and mount them to the frame on the same side as the 8' crosspiece. Finally, fasten the 12"vertical plastic stalk perpendicularly to the 8' rear section half above and half below. Pick up the entire frame by its center pole to establish the balance point, mark that spot, and you'll be ready to string the element wires which form the pattern.

It might be easier to envision the element pattern if you imagine the skeleton of a fish, with backbone and ribs.

Wire the backbone first, using the heavy bare copper conductor. Make the terminals at the front by fastening a No. With that done, install similar fasteners at each end of the vertical stalk, at the rear tip of the center pole, and on one arm of the rear crosspiece at a point halfway between the two poles. Start at the front and run one continuous length of wire from one terminal to a screw on the vertical stalk, over and down to the head on the rear crosspiece, up to the other fastener on the stalk, and back to the remaining terminal at the front.

Pull each section tight as you go, and then wrap the conductor once around each screw. Next, you'll want to make a "reflector" — another length of the same wire stretched between the bolts at the rear corners of the frame and the screw at the tip of the center pole.

It's best to insulate this wire from the screwhead with tape or tubing to isolate it from the metal pole. The ribs of the fish — called resonant dipoles in technical terms — are paired short sections of wire which do most of the signal-gathering work.

They spread out from the backbone spans at angles roughly parallel to that of the reflector. To make them, get a measuring tape and a grease pencil, and starting at the front, mark off the following distances on the top and bottom backbone wires and on the outside of the two plastic side poles:. You should now have four sets of 24 marks each, with the marks close together at the front of the frame and farther apart toward the rear.

Now, set the frame flat with the front pointing away from you and the three long poles on top of the crosspieces. Starting at the rearmost mark on the upper backbone wire, twist and solder the end of your heaviest wire to it, then run it to the rear screw on the right pole section and pull it just enough to take up the slack.One of the great things about digital television is also one of the not-so-great things.

When you get the signal, it's crystal clear. When you've a weak connection, you're out of luck. Boost your reception with this monster homemade antenna. If you live far from urban centers but you'd still like to pick up some over-the-air digital stations, you're going to need a pretty sizable antenna. Earlier this year we shared a great antenna design with youbased on the Gray-Hoverman model. The model you see here is what results when a little Gray-Hoverman antenna visits the beach, gets washed into a deep trench outside of Tokyo filled with radioactive waste, and emerges again, ready to wreak havoc on the world.

Well, all except for that last part. This massive build, based on the Gray-Hoverman model, can pick up signals from around 60 miles away, making it suitable for either boosting your local reception or picking up signals from areas you've never called home. If you're put off by the size of it, it is possible to put this style of antenna inside an attic. You'll lose a bit of reception, but you'll avoid your neighbors whispering about the mutant antenna on your roof. Check out the full build guide at the link below.

I'm so glad the government was so quick to switch from analog to digital. Going from 22 channels to 4 made my life to much simpler. The A. Jason Fitzpatrick. Filed to: HDTV.

What Is A High Gain TV Antenna?

Share This Story. Get our newsletter Subscribe.What are high gain tv aerials? Well, a high-gain TV aerial HGA is an antenna with a narrow radio beam that is used to increase the signal strength. Furthermore, even a High gain aerial may need amplifying weak signals used in bad signal areas and communal systems.

Because High-gain Aerials can also be produced from parabolic TV antennas, phased arrays, and yagi antennas. TV Aerial gains are defined with respect to hypothetical aerials that radiate equally in all directions — the isotropic radiator. This gain can be measured in decibels dBi or, in certain cases, decibels compared to the maximum intensity of the direction of half-wave dipoles dBd.

Also, increasing the strength of the signal that it receives. Therefore, as a result of their reciprocity, high-gain TV Aerials can also make transmitted signals times stronger by capturing more energy when used in receiving antenna.

This property reduces interference. This tradeoff off is done by focusing the antenna gain, which is different from amplifier gain.

Ask any antenna engineer, antenna gain is directly proportional to both the amount of tuned elements for its designed frequency and its size like a telescope, long length allows it to focus the signal stronger.

A small antenna with only 5 elements will have less antenna gain than a longer antenna with twice as many elements for example. Note a signal amplifier gain which maintains the signal already picked up by the antenna is not the same as antenna gain which determines the antenna's actual max range.

Also see more detailed explanation why this is further down. Don't be duped by tiny outdoor tv antennas and flat antennas advertising crazy range, it's impossible due to their geometry and size. This is the antenna for you! Oh and it has excellent performance too!

Stronger Element Size Upgrade! Despite antenna claims found online, the max line of sight range possibe is generally miles max. The reason for this is actually simple, the earth is round and its curvature itself prevents a longer groundwave part.

This antenna helps you achieve the highest line of sight uhf possible with an up to mile line of sight range, option 2 also adds long range VHF as welland offers exceptional Tropo range a well read further down about the Tropo range. Unlikely, if they're smaller. These antennas are commonly imports that grossly exaggerate their claims. Never go by claimed ranges alone.

A much better sense of antenna gain is how large the antenna is in conjunction to how many tuned antennas it has a 24" long antenna with 10 UHF elements will have more gain than a 12" long antenna with only 5 x UHF antenna elements. If your install is high loss, this is easily remedied with an inexpensive, low-loss signal amplifier. You should add a signal amplifier prior to high loss components. See our Signal Amplifier page.

No, absolutely not! No antenna can guarantee that or any range for that matter because of the multitude of factors involved. Ranges are assumed as a best case scenario. Although some customers experience ranges as high as 90 to miles with our insane gain models, this is in a best case scenario with a line of sight path.If you have decided to ditch the cable TV and completely turn to on-air TV broadcast, you are probably more than familiar with the utilities such as TV antennas and digital converter boxes.

Unfortunately, if your signal reception is weak, you will have to add another device to the list — an antenna amplifier. Its main purpose is to turn your poor TV signal into a usable one. Nevertheless, this can be managed with a little bit of research or advice. Finding the ideal amplifier can be a tricky task, but luckily, like many other hardware types, amplifiers also have their particularities, which make things much easier and let you focus on the important stuff.

In other words, you should focus on the following:. Noise levels are one of the most important aspects of a TV antenna amplifier. Lower values mean that the device has better sensitivity and therefore, will provide much better signal amplification. When talking about the exact numbers, noise levels around 2dB or lower are very good, while the values between dB are too high. Gain is probably even more important than noise levels and basically should be equal to or higher than your signal loss.

In other words, if your signal loss is around 10dB, your gain should be at least 10dB or more. For that reason, if your cable loss is 10db, for example, go for devices with a gain between db and not the one with 30dB. Things are pretty straightforward considering frequencies support. If you decide for a device that has a five-year warranty, you are safe and sound for that period, without a need for additional investment.

Yes, this usually means that your initial investment needs to be larger, but once you put everything on paper, you are going to realize that a longer warranty is worth the money. This device includes a mounting kit and highly durable, weatherproof housing that makes it ideal for use at harsh climate conditions.

The amplifier itself allows for gain adjustments and drastically improves the quality of the received signal among other things, it significantly reduces the pixelation and it can even increase the number of obtained channels.
