This section consists of indoor ceiling and wall antennas for cell phone signal boosters/ repeaters/ amplifiers. Typically, a cell phone signal booster kit includes one inside antenna (Panel antenna for walls/ ceilings or Dome antenna for ceilings). Sometimes, that single dome/ panel antenna does not help penetrate the cell phone signal to those deep interior spaces far from your installed interior antenna due to thick walls of apartments, homes, offices, etc. With our super indoor antenna expansion kits shown below, you can now expand indoor cellular booster coverage deeper into more rooms or office spaces.
These cellular coverage expansion packs for indoor use are very easy to install because they contain all needed parts - Extra add-on indoor antenna(s), cable(s), and splitter to connect additional inside building antenna(s) to your cell phone signal booster kit. Such a complete antenna kit with all required parts can help you to easily expand indoor coverage further and help you to make the most of your cellular signal amplifier kit.
If you have arrived from one of our signal booster kit pages at this website, the following are correct ones to purchase for that signal booster kit on that page. Antenna impedance of 50 Ohms or 75 Ohms must match your amplifier’s impedance. The following kits are for 50 Ohm booster systems. We carry 75 Ohm antenna expansion kits as well, if you have a 75 Ohm booster kit. Scroll down below listings if you wish to read advantages of Dome versus Panel inside-building antennas.
Dome type building antennas are best used in open spaces such as in the center of a round or square room. They can be mounted on a ceiling in a central location where increased coverage is desired so that signal radiates and covers entire room or space.
Panel in-building antennas are best used for long hallways or corridors and when cell signal needs to penetrate floors and ceilings. They can be mounted on a wall facing the direction where increased coverage is desired (such as a hallway or longer direction of a rectangular room/space). They can also be mounted on ceiling to radiate signal downwards across multiple floors below. Please note that the power of signals being able to penetrate walls, floors, and ceilings depend upon the strength of incoming signal to the booster and the construction material such as metal, concrete, brick, wood, or drywall (in that order from higher to lower resistance).
Multiple indoor antennas are best used to increase coverage deeper within a large home or building that has rooms and office spaces spread out in various different directions. They are helpful for boosting signal over multiple floor levels, within expansive single story houses and businesses. They may also be needed for densely constructed buildings such as those with thick internal concrete walls. All cell phone signal booster kits have one interior antenna with the kit which should suffice. However, expansion kits shown above can help realize the boosted space a signal amplifier is capable of increasing signal over, if the walls, ceilings, and floors have too much resistance due to dense composite.
