How to Aim a Yagi Directional Outside Antenna


Directional antennas, unlike omni-directional antennas, must be aimed in order to receive the strongest signal from your cellular carrier(s). Here are some things to know ahead of time:

  • Most directional antennas can cover about 15% of the horizon (between 50 and 60 degrees), so your aiming doesn’t have to be laser-precise. Being off by a little will still work just fine.

  • In almost all situations, the antenna should be level and even with the horizon. Do not attempt to aim the antenna up over a roof or nearby obstacles.

  • You should attempt to aim the antenna before deciding where to permanently mount it. Once you know what direction the antenna should be pointed, try to find a location on the building so that the antenna is pointed away from the building. For example, if you need to aim your antenna North, you should mount the antenna on the North side of the building pointed away from it, not on the South side pointed over the building.

Even if you know exactly where your carrier’s tower is located, it’s still a good idea to go through this aiming process! The cell signal may not be coming directly from the tower either because of obstacles in the way (buildings, hills, etc.) or because the tower may not have an antenna aimed in your direction

Preparing to Aim the Antenna

To start, temporarily setup your signal booster system by running the cables through doors or windows, connect everything together, and power on the system. To aim the antenna, you’ll ideally need two people. One person will stay inside with a cell phone from each carrier that you want to support. The phone(s) should be in Field test mode so you can take decibel signal readings, which are more accurate than bars. Place the phone(s) on a table or other surface between 10 and 20 ft. away from the inside antenna and leave them in the same place until the aiming is completed. If it’s a directional inside antenna, be sure that the front of the antenna is aimed directly at the phone(s).

The second person will be up on the roof (or wherever you plan to mount the outside antenna) and will be aiming the outside antenna. Ideally, you want the antenna mounted to a pole that you can hold rather than holding the antenna directly since holding the antenna can affect the performance.

Process for Measuring Signal Strengths

1.Start with the outside antenna aimed in one direction. The person inside should then wait 60 seconds and then record the signal readings from the phone(s). It’s also a good idea to check the warning lights on the booster to record any warnings you see. Our repeaters with LCD display will also show on –time signal strength outdoor antenna caught.

2.Next, rotate the outside antenna 45 degrees or 1/8th of the way around. This can correspond to the 8 compass points (N, NE, E, SE, S, SW, W, NW). Once the antenna has been rotated 45 degrees, the person inside should again wait 60 seconds and then take another set of signal readings.

3.Repeat this process until you’ve aimed the outside antenna in all 8 directions and have 8 sets of signal readings.

Interpreting the Results

Once you have the signal readings, you’ll want to find the direction that gave you the strongest readings for all of the carriers that you want to support. If you took decibel readings, then look for the readings that are closest to 0. For example, a -70 dB reading is better than a -90 dB reading. The stronger the signal, the more coverage you’ll get from the system.

Once you’ve identified the correct direction, find a location to mount the antenna so it can point in that direction with as few of obstacles as possible. Ideally, you want the antenna on that side of the building pointing away from the building.

Handling Warning Lights During the Testing Process

If, while testing, you find that there are warning lights on the booster. If the warning light is due to oscillation (feedback), try retesting in that direction but increase the separate between the inside and outside antennas. If the warning is due to overload (too strong of a signal coming from a nearby tower), then the aiming process will still work correctly by helping you find the direction where the system performs the best. In either case, you should try power cycling the booster after re-aiming the outside antenna to ensure that the booster isn’t shutdown due to conditions at the previously aimed direction.

In some rare cases where you receive overload warnings and you aren’t able to get the system to work well, it may be necessary to try different outside antenna locations or to add inline attenuators. Contact us for help troubleshooting these situations.


Q:  The signal in some area is still not strong enough after installation. Why?

A:  It is because that the indoor/server antennas are not enough. Please install more indoor/server antennas in those areas with weak signal.


Q: The signal in all the area is not strong enough after installation. Why?

A:  It is because that power of the signal repeater is not big enough for the needed area. Please choose a higher power repeater or increase the repeater quantity.

Q: Why choose us for cell phone signal boosters?

A: Mobile network coverage in many countries is a common problem that many people experience. For more than 10 years, Wingstel repeater has been developing high quality cell phone signal boosters. Our range of quality assured and certified products guarantee absolute customer satisfaction.

Q: How to know carrier frequencies?

Cell phones communicate with cell towers using radio waves and these signals operate on various frequencies. While it used to be that you would need to choose a cell phone signal booster that supported the frequencies that your carrier operated on, now every new booster supports all of the major frequencies (typically referred to as 5 Bands), so any new booster will work for you.
