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 on phone is not steady, or it shows full bar, but can not call out. Why?

A: Please make sure the outdoor/donor antenna and indoor/server antenna are connected to the right port on repeater. The outdoor/donor antenna should be connected to BTS port while indoor/server antenna to MOBILE port. 

Q: How many kinds of signal booster components?


 5a. Outside Antennas

There are two different types of external antennas that you'll encounter when deciding on a signal booster for your cell phone, omni-directional and yagi/log periodic (directional). As you decide how to boost cell signal in your situation, you must determine whether you need to boost cell signal in just one direction or in all directions.

Omni-directional antennas are designed to send and receive signal in all directions, so you're able to reach multiple cell phone towers at the same time and boost cell phone signal for multiple providers. If you have a moderate to strong signal in the area that you're going to be placing your external antenna, then an omni antenna is good for you.

Yagi antennas/Log periodic antennas are designed to send and receive signal in a specific direction, so while you're not able to cover a full 360 degree area, you're still able to cover a portion of the horizon and reach a significantly greater distance to cell phone towers that you would not be able to with an omni antenna. If you have a weak outside signal, and you have a fairly clear line of sight (no mountains in the way) then a yagi antenna/log periodic antenna is a good option for you.

5b. Amplifier Power

Amplifiers are rated in decibels (dBs), which measure how powerful the amplification is. Decibels are a logarithmic measurement, which means that for every 3 decibel increase, the amplifier actually doubles in strength (which also means for every 3 dB decrease, it is half as strong). If you're amplifying a weak signal and want to be sure that you'll cover the full area, choosing a stronger amplifier can be the solution.

5c. Inside Antennas

There are three different types of inside antennas to choose from when selecting the components for your cell signal booster system: whip, dome ceiling and panel antennas. The signal booster kit that you choose will determine what your inside antenna options are.

Whip antennas are designed to attach directly to the inside antenna port on the amplifier and radiate signal outwards in all directions. They are typically a lower gain than dome or panel antennas, but do not suffer the cable signal loss that the other antenna options are subject to. Whip antennas are only found on entry to mid-level systems, and are only used to cover a single room, or multiple rooms with cell signal.

Dome ceiling antennas are designed to cover one floor with signal in all directions and are meant to be mounted on the ceiling the center of the space in order to broadcast and receive signal equally in all directions. They should not be used for multiple floors of coverage.

Panel antennas are designed to broadcast and receive signal in one specific direction, and are best suited for either long, rectangular spaces or multiple floors in a house or building. They can be mounted on the wall facing down a space or mounted facing downwards at the top of a space and broadcast down and out through multiple floors.

5d. Cable Types

Cable is used in all systems to connect the antennas to the amplifiers. Unfortunately, cables are not perfectly efficient and will lose some signal in transit, depending on the type, quality, and length of the cable. Ultra Low Loss LMR-400 cable loses 2 dB of signal over 50 feet while standard RG6 coaxial cable (like you use for cable television) loses 5 dB of signal over the same distance. When possible, you should use the shortest and highest quality cable available to ensure that a minimal amount of signal is lost from the antennas to the amplifier. If you have extra cable, you can cut it and add a connector to the new end, but this may require special tools. In general, always try to buy the correct length of cable while allowing a little extra just in case.
