A minimum of 25 to 30 feet horizontal or vertical antenna separation is important to prevent oscillation or feedback in any in-home cell phone signal boosting system. Read some helpful tips on how to prevent oscillation by using various antenna separation distance techniques while installing your in-home cell phone signal booster system.

You don't want to experience oscillation or feedback in your system so you need to learn about the importance of antenna separation.
We have all experienced feedback before. It occurs when a microphone and speaker are too close together. You get a loud screeching noise. The booster operates in the same manner. If your booster is experiencing oscillation or feedback, it will lower its antenna gain output down or power itself off. It will initially only decrease your coverage area on the inside antenna. If oscillation is bad enough, it will turn the booster off itself. This is one of the requirements for amplifiers to receive certification by FCC to prevent damage to the wireless network or cell towers nearby.
To begin the installation, find the best signal location for your external antenna. To install your internal antenna, keep 25 to 30 feet of vertical separation between the two antennas. If you're not able to accomplish this, go to a horizontal separation. However, you will need more distance between the two antennas. Install the two antennas facing away from each other. With some antennas, all of the broadcast area comes out of the front of the antenna. There's little radiation coming from the back. Install the antenna in the roof or a rafter situation facing down into your home. This will provide the best coverage. An outside antenna may be an omnidirectional antenna. You will need more separation between your internal and external antennas. This is because the omni antenna broadcasts in a 360 direction.
Look at the booster. Are the lights red? This will indicate that you need a little bit more separation between the internal and external antennae.
If you follow these steps, you will prevent oscillation in your home cell phone booster system installation and your cellular signal amplifier will be able to provide you with the best coverage. Hopefully, these tips will help you to get the most out of your mobile signal booster. If you need more explanation or details, watch the video or contact us with your questions.
