How do omnidirectional antennas work




















They need to be mounted to the ceiling for best results. They offer coverage across one floor and are not suitable for covering multiple floors. Panel antennas are directional antennas.

Panel antennas allow optimum reception to targeted areas. Like with outdoor antennas, a directional antenna is stronger than an omnidirectional antenna which means the signals it broadcasts are stronger.

It can be mounted to either the wall or ceiling. We usually recommend placing it on the ceiling for maximum coverage but in some spaces like a long narrow hallway the panel antenna can be placed on the wall. Outside antennas should be placed as high up as possible , in the area receiving the best possible signal see our site survey guide to help you figure out where that is in your building. A yagi directional antenna will need to be pointed in the direction of the nearest cell tower.

It is important that you are not in contact with the directional antenna when taking a signal strength reading. Contacting the antenna can produce inaccurate readings, which can lead to less than optimal yagi antenna positioning and reduced performance from your amplifier kit. They can be attached to a roof, a wall, or a pole. Inside antenna placement depends on the layout of your building and the area you want covered.

If you just want to improve signal in one room, like a home office, the best place for the antenna is in the middle of the ceiling. Hi Luis, Thanks for writing. Feel free to shoot us a note to support ubersignal.

I do a lot of traveling for work and stay at hotels on a weekly basis. While in the room, I normally only get a single bar of service. I'm looking for a solution that can boost my Verizon LTE phones signal and that is portable as I would like to take it from room to room. I'm currently still grandfathered in on the unlimited data and don't want to lose or change that. Hi Kyle, Thanks for writing. You'll be able to move that from room to room, and the cradle will significantly boost the signal for the phone while the phone is resting in it.

Take a look at that and let us know if you have any additional questions at support ubersignal. They work great in the city Milwaukee, Wisconsin suburbs but when we went up north central Wisconsin the service sucked Before this we had Verizon flip phones and never had a problem with service. Since we go up there pretty much every other weekend and have a family member with a heart condition, we need reliable cell service.

We just watched your video on how to install a zBoost YX Do you think that model would solve our problem? Hi Jay, Let me know the answers to the following questions and based on that, we can recommend a system for you: - What kind of an inside space are you trying to cover and what is it made out of?

For example, is it a house, trailer, concrete bunker, or something else. Based on that information, we can recommend a system for you. I live in an apt complex and have access to bars and 4G outside and inside Verizon. The signal fluctuates drastically inside the apt and I'll have 3G one minute and then no signal seconds later.

Typically I will have to call someone back times in a 20 minute conversation The best results are by the back door or near a window and even then I have to stand still otherwise I lose the call. Oddly enough, I've noticed that the ac unit actually causes some kind of interference that results in dropped calls.

Yes, the ac unit causes dropped calls if I happen to be on the phone when it kicks on. I can put something inside the window or perhaps on the porch outside, but I'm limited on the direction that the antenna can be positioned I have started researching this, but figured I would go directly to the experts and ask your opinion. Thanks in advance. Hello Jason, Apartments where you can't mount an antenna outside on the roof can be difficult. Sometimes, it's helpful to take you phone and walk around the outside of the building and see if one direction seems to get stronger signal than others.

That's likely the direction of the tower. If you have a window pointing in that direction, that's likely the window you would want to use for a receiving antenna.

Assuming you have a window where you can get at least one bar of signal, then a signal booster may still be possible, but your coverage area will be on the small side. The "outside" antenna can be mounted to the inside of a window.

With a weak 1 bar signal, you'll only get a very small area of coverage, just a few ft from the inside antenna. If you can get a stronger bar signal at that window where the "outside" antenna is, you may be able to cover 1 room.

Overall, it will give you place where you can put your phone and know you shouldn't drop calls, but will definitely not give you complete coverage over your entire apartment.

When to Use Omni antennas are best suited for situations where you need to support multiple cell phone carriers, each with their own cell tower, and are already receiving at least three bars of signal outside of your building or vehicle.

Find out if a Directional or Omni-Directional antenna best suits your needs. All antennas have a specific use case. In order to determine whether a Directional or an Omni-Directional antenna is best, you need to know the basic functions of both!

An Omni-Directional antenna radiates and receives the RF energy equally, providing a degree radiation pattern which allows connectivity in all directions.

A Directional Antenna has a radius of around 45 to 90 degrees, focusing RF energy in a required direction and limiting connectivity to that particular area. This can help overcome interference and multipath, providing better and more structured coverage. Generally, Omni-Directional antennas are easier to install due to their degree radiation pattern, you can place them anywhere you require. They are compatible with a variety of cellular base stations and usually have lower Gain with more redundancy.

The more cellular base stations involved, the less concentrated the connection will be. A Directional antenna reduces interference from other directions, with higher throughput, but it is limited to a specific base station capacity.

This means that these antennas are very dependant on a cellular tower availability. The diagram below shows how Directional and Omni-Directional antennas receive cellular base stations. It is important to note, that higher antenna Gain does not always mean better. The only difference is that it uses one metal conductor and a conductive surface ground plane , such as the Earth.

The ground plane is connected to the transmitter's ground wire and serves as a reflecting surface for radio waves. The metal conductor is half of the dipole and ground plane is essential the other half. Omni-Directional Antennas in Practice How does this look in practice? After installing a cellular signal booster also known as a signal repeater or extender an electrical current will be supplied to the omni-directional antenna.

The antenna's components will create an electromagnetic field around it. Cellular, etc. The cellular signals are fed to the amplifier via coaxial cable for boosting. These waves travel through the signal booster system and are broadcasted into the air by the outdoor antenna.

The wave travels at the speed of light in the direction of where the signal source is located. There are three main differences between omni and directional antennas : shape, radiation pattern, and range. Directional antennas, such as Yagis, grids, parabolics, and panel antennas, are more powerful than omni-directional antennas. Traditional directional antennas tend to have a beamwidth of 45 to 90 degrees.

Long-range directional antennas can have a beamwidth of 7 to 10 degrees. Under perfect conditions, and depending on the type of directional antenna, they can reach over 10 miles.

They are ideal for weak signal areas where cell tower distance is the biggest issue. A signal booster with a Yagi antenna, for example, will only be able to amplify carrier signal that falls within that pattern. To amplify multiple carriers in areas with distant cell towers, multiple Yagi antennas pointing at different cell towers may be needed. Omni-directional antennas, such as dipoles, monopole, and whip antennas, on the other hand, send and receive signals from every horizontal direction - degrees.

Thus, they are not as powerful as directional antennas. In this case, to amplify multiple cellular signals, you would only need one directional antenna. The main drawback associated with omni-directional antennas is that they can easily interfere with outdoor or indoor antennas nearby if there is not enough distance between them, degrading performance.

The below information will relate to cellular signal specifically, but Cellular omni-directional antennas work best in situations where:. With multiple cell towers no more than 5 miles away, the antenna will be able to pick up multiple signals from every direction. If the towers are more than 5 miles away, a directional antenna will be the better option. Obstacles sitting between nearby cell tower and your homes, vehicle, or place of work, such as tall buildings, dense foliage, valleys, and bodies of water, can absorb, reflect, and refract incoming radio waves, altering their direction.

In this case, an omni-directional antenna is perfect - it can pick up the inconsistent cell signals from any direction.
