How Does It Work?

Unidirectional LPDA / Yagi exterior antenna catches signals from farthest away when pointed towards the nearest relevant carrier's cell tower. Then the main signal amplifier box amplifies those signals. Then interior omnidirectional dome antenna broadcasts that amplified signal inside building structure towards all directions with up to 2000 sq. ft. radius.

Requirements For It To Work.

With its Yagi antenna, it is ideal even for locations with weak signal strength outside. Based on signals it can catch from cell towers miles away, it provides improved cell phone talking clarity and faster data speed on all cellular devices such as tablets and mobile hotspots in an office or home, up to 4,000 sq. ft. with good signal outside. Coverage will be lower if signal is weaker outside.

Cable length customization.

For most practical purposes, included cable lengths will suffice for installation. However, in rare situations longer cable may be needed due to distance between antenna, and signal amplifier unit. Secondly, in some cases where signal that exterior antenna can capture happens to be very weak to provide enough interior improved coverage space, a customized shorter cable will be best to minimize signal loss. The reason for this is that cables incur signal loss so longer the cable, more the loss of signal incurred. Therefore, see below for optional cable purchase suggestion to facilitate installation and/or better performance.

Optional Available Cables and Accessories.

Cables incur signal loss. Therefore, shorter the cables, the better the performance. While this kit includes required outside cable, you may buy a different specific size cable to meet your needs. If longer or shorter outside cable needed than included size, a different size RG6 cable with F-Male connectors can be purchased separately. For even better performance, select from low loss RG11 cables to upgrade outside antenna cable (must be bought separately).

Although this purchase has all other components required to install the system per se, the following accessories may make the installation easier and help protect the system in the future:

  • J-Bar Pole Mount For Outdoor Antennas: Adjustable 20" J-bar outdoor antenna mounting pole is a universal mounting pipe that allows you to position your exterior antenna higher for optimal reception. The bracket attaches to any flat surface including a roof, fascia, side of house, or deck rail (SC-MOUNT-JBAR).
  • Lightning Surge Protector (75 Ohm) for SC-RG6 and SC-RG11 coaxial cables: In-Line Surge Arrestor With F-Female and F-Male connectors for SC-RG6 and SC-RG11 coaxial cables protects signal booster from damaging electrical surges (SC-LP-75). Or choose 75 Ohm surge protector.
  • Grounding kit helps ground the surge protector to disperse lightning surge.
  • Need longer cable run? Get 50 Feet Premium Low-Loss 75 Ohm RG-11 coaxial cable with F-Male connectors (SC-RG11-50).*
  • Need even longer cable run? 100 Feet Premium Low-Loss 75 Ohm RG-11 coaxial cable with F-Male connectors (SC-RG11-100).*

*Upgrading from included RG-6 cables to lower loss RG-11 cables may be helpful because longer the cable, higher the signal loss. For every 100 feet, the signal loss is approx. -4dB on low frequencies and approx. -6dB on high frequencies. Therefore, it is best to use shortest runs possible. If using longer runs, outside signal strength should be good to support the Gain loss. Please contact us if you need assistance regarding your situation.

Questions & Answers


Ask a Question
  • I have identified this home signal booster unit model # SC-PolyH-72-YU-Kit that I would like to buy. However, I would like to protect the system from lightning strikes that have been occurring in my area quite frequently (can global warming cause this?). Anyway, I just want to know the model number of the lighting surge arrestor to purchase for that system. It looks like I have an N connector on one side of the cabling with this kit and a F style connection on the other side. So I would need a lightning arrester that has one of each connector I think.

    The 75 Ohm lightning surge protector part model number SC-LP-75 is for this Fusion4home kit. Its male side should be connected to the outdoor antenna and the female side should be connected to the coax cable that goes into home or building.

  • How to find the best signal direction?

    One way to do that is to point your exterior antenna in the direction that yields maximum signal inside (after installation of the system which includes exterior antenna, interior antenna, and main base unit - all connected per instructions via coaxial cables included).

    This can be done in few degrees increments every 5 minutes for testing purposes or you can rent a signal meter to do this task faster.

    To test more accurately using your phone, put it in field test mode which is more accurate than relying on signal bars that are not realtime nor accurate many times.

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

Kevin K. of Anderson, California gave the following review:

Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

If outside signal is too weak (weaker than -110 dB), submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

For non installation-included kits: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
