Product Description

Premium quality expansion kit contains three Dome Ceiling Mount Antennas plus all the components needed to connect them to an existing 50 Ohm cell phone booster system. This is our premium signal booster custom batch # 7 inventory item: 3 Interior Ceiling Mount 50 Ohm Dome Antennae with 4-way Splitter and Cables. UPC: 697691010274.

Mount the dome antennas in areas where the cellular reception is weakest. This can be up to 50 feet away from the existing antenna if the cables that are included in the kit are used. For longer distances, extension cables can be purchased separately. The kit comes with N-connectors and is compatible with any 50 Ohm cell phone booster and repeater including Uniden, Hiboost, SureCall and Wilson weBoost. 

Expansion kit installation is straight-forward. The dome ceiling antenna can be easily installed through a small hole made in a suspended ceiling tile. Use both the 50 foot 400 series cables provided with the kit and the existing cell booster cable to connect the antennas to the Signal Splitter. The signal splitter is then connected to the cell booster using the 2 foot jumper cable provided.

This expansion kit includes:

  • 3 x AFCAC0827G03FNFP4 50 Ohm In-Building Dome Antennas.
  • 1 x AFCCS0727S4NFM7 50 Ohm 3-Way Wideband Signal Splitter.
  • 1 x 2 ft. AFCAX-400 Low Loss Cable (N-Male to N-Male).
  • 3 x 50 ft. AFCAX-400 Low-Loss Cable (N-Male to N-Male). expansion kits provide an easy way to expand the cell coverage in your office or home. It might also be a good idea to add lightning protection to safeguard your outdoor antenna and booster against any electrical surges. recommends the AFCLC03NMNFBC3 50 Ohm Lightning Surge Protector shown in accessories section.

Antenna details.

The AFCAC0827G03FNFP4 High Performance Ceiling Antenna is omnidirectional and provides wide coverage and high gain. The downward radiation pattern has been optimized for both WiFi and cellular signals. All 2G, 3G, 4G and LTE cellular bands, as well as the 2.4 GHz WiFi band are covered. This makes the antenna ideal for use not only with cellular boosters, but also with in-building wireless DAS networks used to distribute Cellular and WiFi signals through an area or building. 

This discreet, attractive white dome blends in with home ceilings and commercial office environments. As it mounts directly via a small hole in a drop ceiling tile, no backing plate is required. It can however also be attached to fixed ceilings or other structures with an optional bracket. The antenna can be used outdoors, providing it is mounted in a dry location. 

The antenna is compatible with any 50 Ohm cellular booster, including Hiboost, Wilson and Surecall. An N-Female connector is used to terminate the antenna lead. For increased coverage, many units can be connected using a a directional coupler or signal splitter. All antennas are fully tested before shipment.

4-Way Signal splitter description.

The AFCCS0727S4NFM7 is a 50 Ohm signal splitter which is used to divide a signal evenly between 4 output ports. It is weather-proof and can be used for indoor and outdoor installation.

This signal splitter is compatible with any 50 Ohm cell phone booster and repeater including Uniden, Hiboost, SureCall and Wilson weBoost. It is typically used to connect several indoor antennas to a single booster. They are also often used to couple or "stack" many outdoor antennas together to increase gain or shape signal coverage.

This wide band splitter operates at all cellular bands from 698 MHz to 2700 MHz. This design allows it to be used with many frequency bands making it useful for many applications including 900MHz and 2.4GHz WiFi and wireless video systems. They use an efficient micro-strip design which has low VSWR and insertion loss.


  • Compatible with any 50 Ohm Cell Phone Booster, Amplifier and Repeater.
  • Full Band Coverage (698 MHz to 2700 MHz).
  • Low VSWR and insertion loss.

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.
