No outside antenna home cell phone booster kits.

If you're looking for a cell phone signal booster without exterior antenna installation, you have come to the right place. Small, mid-size, large home, office, apartment / condo all-carrier cell phone booster with window antenna works to boost cellular signals of all cellular carriers. These include Verizon Wireless, AT&T Wireless, T-Mobile, Sprint and all others including all MVNO's.

This is a phone booster that does not need outside installation of antenna on the roof, external wall, etc. making it time-saving and convenient to install as well as possible to do so in places that have no access to roof or outside wall of building. This is a cellular amplifier with no outdoor antenna required.

It is an excellent option if you have outside antenna installation limitations on your property (rented or not allowed by HOA) as long as you have some signal inside near a window, etc., (at least -110dB 3G, -120dB 4G). Check signal strength accurately in Decibels beside all windows to make sure you have enough signal strength required at any spot in the house or office for any of these kits to work.

No installation cell phone signal booster.

No external antenna cell phone signal booster consists of a window-mountable antenna that is almost 1 foot in diameter. The window mount signal catcher is designed for placing near window with best signal or attaching directly on the window using included mount. It is the donor antenna that catches signal from outside to amplify indoors. If you still need help, SignalBooster.com offers the best building cell phone signal booster options and professional installation services by certified and experienced installers. Based on amount of square footage that requires cellular reception enhancement, a suitable bi-directional amplifier (BDA) system chosen from menu shown, can help boost mobile coverage.

The multiple choice drop-down menu provided above gives you the choice to select the best wireless coverage boosting system to cover weak signal areas. Coverage can range from all space within small to large house / office depending upon the strength of signal outside, and the power of residential or commercial signal booster system chosen.

It works the same for homes, offices, retail stores, business warehouses or other types of commercial properties. Installation instructions are included with toll free phone support, if needed. The prices shown are only for equipment so please contact us for certified installation cost, if required. If within budget, we can schedule time-frame for installation anywhere within United States.

How does this building cell phone signal booster work?

This cellular signal booster or amplifier kit consists of 3 main parts - Window mount donor antenna, signal amplifier base unit, and interior antenna(s):

1. The donor antenna captures signals from nearest cell towers through a window that has good reception.
2. The coax cable connected to window signal catcher sends that signal to signal amplifier base unit which boosts those signals to multiply them many times and then transmits them to interior building antenna(s) via coaxial cable(s).
3. Finally, the in-building antenna(e) distribute the strong wireless signals to poor signal areas to enhance cellphone reception considerably to enable fast 3G, 4G, LTE Internet and clear mobile phone conversations.

Important notes:

• Outside signal strength: Since signal boosters require existing signal outside which they use to amplify and distribute within any building structure, the size of boosted coverage area provided indoors is dependent to a great extent by the strength of signal available for donor (window) antenna.
  
  Therefore, actual coverage cannot be predicted with certainty. This is the reason why you will see that any booster kit being sold states, "up to" a specific amount of square footage. No booster can guarantee an exact amount of coverage it can provide. Any stated coverage area in square footage, is merely an estimation.
  
  
• Antenna separation: Amplified signals are transmitted in the room by interior antenna that must be positioned at least 30 feet away from the window receiver where there's weak signal you want to improve. Smart phones, tablets, mobile hotspots, and all other cellular devices then receive the signals from their specific carriers. However, lack of separation may cause oscillation or feedback which will cause booster to automatically reduce its output power / Gain amount.
  
  30 feet separation is suggested between the window antenna and dome/panel antenna(s), but you may be able to get them closer together depending on the materials blocking the signal if there is a wall in between or a piece of furniture that is blocking clear line of sight between window and interior antenna(s). We recommend a "soft install" where the antennas are loosely placed to determine if there is any potential problem indicated by LED lights on base unit. If space constriction exists, Faraday products that block signal may be the solution to that problem.

What are the differences between suggested in-building cell phone booster kits?

The first distinction among kits in the drop-down menu is the boosting power of respective signal amplifiers. For example, mid-size building kits are more powerful than the small building kits and less powerful than the large building kits. Powerful means they offer higher "Gain" or increase in signal when it comes to amplifying the signals caught by the signal catcher (window antenna).

The second distinction among kits in the drop-down menu is the type of interior antennas. "Dome" antennas typically installed centrally on ceilings broadcast signal omnidirectionally in 360 degrees fashion. "Panel" antennas typically installed on walls broadcast signal unidirectionally in a single direction like along hallways and long corridors or if installed on ceiling - across multiple floors.

The third distinction among kits in the drop-down menu is the number of interior antennas included - one, two, or four. More interior antennas provide greater ability to distribute signal in more areas of a building such as in rooms spread out over large area, or on multiple floors, or in the basement, etc. Multiple in-building antennas require multiple cables and splitter to connect to the base amplifier unit which are included in the respective kit.

Coverage square footage in context of Small, Medium, Large Homes / Offices:

Coverage area will vary greatly based on the signal strength at the window antenna placement location. With good signal strength, you can achieve following approx. boosted coverage spaces:

• Small Homes and Offices: Up to 2,000 sq. ft.
• Mid-Size Homes and Offices: Up to 5,000 sq. ft.
• Large Homes and Offices: Up to 10,000 sq. ft.

Cable lengths:

Small home single interior antenna kits contain one 30 ft. and one 75 ft. low dB loss SC-400 coaxial cables.

Small home dual interior antenna kits contain one 75 ft. and two 50 ft. lengths of SC-400 low loss dB coax. cables with 2-way splitter and connecting cable.

Medium home single interior antenna kits contain one 75 ft. and one 100 ft. SC-400 low dB loss coaxial cables.

Medium home four interior antenna kits contain five 75 ft. lengths of SC-400 low loss dB coax. cables, 4-way splitter with connecting cable.

Large home single interior antenna kits contain one 30 ft. and one 75 ft. SC-400 low dB loss coaxial cables.

Large home four interior antenna kits contain five 75 ft. SC-400 low dB loss coax. cables with 4-way splitter and connecting cable.
