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. There will be slight degradation or signal loss of 1-3dBi at point where N connector from outside antenna cable connects to F connector of amplifier's outside antenna port cable, but up to 10dBi Gain offered by the window antenna will offset that loss.

    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.

Questions & Answers

QUESTIONS & ANSWERS

Ask a Question
  • I talked with my electrical contractor who attempted to install this kit last week who said that the adapter which you sent would weaken the signal. Is that true? I have a small retail space (900 sq. ft) in a outdoor shopping mall and I am not allowed to put anything outside or on the roof. So need a window antenna. 19 foot ceilings. 2 walls are cinder block. Front wall is all glass. Can you let me know what I need to fit my space?

    The kit you have should work fine with connector although it will attenuate signal by up to -3dB. The reason we say it should work fine is that the Window Catcher antenna offers up to +10dB Gain which should offset the signal loss caused by connector.   Nevertheless, you can also try a more powerful kit which will also not require that connector because its exterior antenna port has the same 50 Ohm impedance as the Window Catcher antenna.   Neither of these options will require you to mount antenna outside. You can place window antenna against the glass in the front of the store facing out which would look like a fancy device sitting there. Then you can place the signal booster main unit against the back wall of the store.

    Try to place both components in such a way that there're as many obstructions as possible between the two (desks, tables, display cases, etc.) for maximum separation so that there's no feedback or oscillation between the two components.

  • Just wondering if SKU / Model: PolyDTO+SC510W would work for Canadian carriers, namely Telus. Thanks.

    It would, but it is not certified for use in Canada. Therefore, you must buy the complete kit certified for use in Canada shown at the link, https://www.signalbooster.com/products/surecall-flare-canada-3g-4g-lte-3-watt-signal-booster-for-home-office-3000-sq-ft and optionally buy the Window Catcher antenna shown at the link, https://www.signalbooster.com/products/surecall-signal-catcher-sc-510w-wide-band-directional-window-mount-antenna

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

    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.

Warning

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. Please check outside signal level in decibels before ordering. 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.

If it is too weak, 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.

Please note: 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.
