Have you purchased or planning to purchase 75 Ohm signal booster kit for your home, office, or building and feel you would need more indoor antenna(s) for those deep interior rooms where reception does not reach using the single inside antenna that is included with the kit? Sometimes, that single dome/ panel antenna does not help penetrate the cell phone signal to those deep in-building spaces far from your installed Dome/ Panel interior antenna due to thick walls of apartments, homes, offices, etc. This section consists of complete antenna kits containing indoor ceiling or wall antennas, cables, and splitters for your cell phone signal booster/ amplifier/ repeater.
With our superb 75 Ohms 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 can help you get more signal boosting capability from your cell phone signal amplifier kit. These Dome and Panel antenna expansion packs include all required parts you will need such as additional cable(s) and cable splitter to connect to your existing cellular phone signal booster 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 75 Ohm booster systems. We carry 50 Ohm antenna expansion kits as well, if you have a 50 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.
