75 Ohm Home/ Building Antenna Expansion Kits

75 Ohm Internal Antennas: Dome versus Panel.

75 Ohm Dome (360 degree beam-width) inside home/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.

75 Ohm Panel (70 degree beam-width) inside home/building antennas.

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).

One versus Multiple 75 Ohm Internal Antennas.

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.
