Product Description

No exterior antenna cell phone signal booster kit.

Small room or office space plug and play cell phone signal booster without external antenna works to boost cellular signals of all mobile carriers including Verizon Wireless, AT&T Wireless, T-Mobile, and Sprint. It is a phone booster that does not need outside installation of antenna on roof, exterior wall, etc. Therefore, it is excellent for high rise apartment buildings and offices where access to roof is not available. Need more coverage than one room? Browse higher gain cell phone boosters with window antenna that also do not require external antenna installation. This is a cell booster without installation requirement because it is practically plug and play. It is a cellular amplifier with no outdoor antenna required.

The multiple choice drop-down menu provided above gives you the choice to select the custom style that you would prefer. They both work in similar fashion except one has desktop amplifier with built-in interior antenna, and another can be mounted on a wall like a wall mounted cordless phone. The latter has a visible whip antenna that is attached to amplifier itself. Both are plug & play - easiest signal boosters to install in under 5 minutes. You may call us if you need any assistance over the phone to help with installation and set-up.

Coverage can range greatly depending upon the strength of signal at the window where you choose to place the window antenna included with this purchase (instead of outside roof mounted antenna requiring installation outside home/ office/ apartment). The window-mount antenna is almost 1 foot in diameter. This window mountable signal catcher can be attached directly on the window using included mount. It works the same for homes, offices, retail stores, business warehouses or other types of commercial properties.

How does this cell phone signal booster work?

This cellular signal booster or amplifier kit consists of 2 main parts - Donor antenna, and signal amplifier with attached antenna (wall mount version) or built-in interior antenna (desktop version). This is how it works:

  1. The donor antenna placed near window captures signals from nearest cell tower through the window.
  2. The coaxial cable connected to window antenna sends that signal to desktop or wall-mounted signal amplifier placed where reception needs improvement. 
  3. That cellular amplifier base unit then amplifies or repeats those signals to multiply them many times and broadcasts them around through attached whip antenna (wall-mount version) or through built-in antenna (desk top version).
  4. Cell phone reception is enhanced all around the base unit 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 the desktop unit 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 between both units may cause oscillation or feedback which will cause booster to automatically reduce its output power / Gain amount.

    30 feet separation is suggested between the two units, but you may be able to get antennas 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 both antennas. 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.

Please note: If you need coverage improvement in more than one room, consider our higher gain cell phone boosters with window antenna that also do not require external antenna installation.

  • How far apart do the two antennae need to be to avoid a feedback loop?
