Description
The SureCall 3G/4G Dome Antenna is an indoor-only, ceiling-mounted antenna that distributes a booster’s amplified signal throughout a room once it’s already been captured from outside. It doesn’t transmit to a cell tower itself — it works alongside an outdoor antenna and amplifier, taking the boosted signal those components generate and spreading it evenly across an indoor space.
Its low-profile, disc-shaped housing mounts flush to a ceiling and blends into nearly any interior, whether that’s a home, office, warehouse, or retail floor. Because it radiates in a full 360° pattern, it doesn’t need to be aimed at anything — it simply broadcasts downward and outward to every phone in the room. Coverage from a single dome antenna is generally best suited to one open room or a small floor; larger or multi-room spaces typically call for multiple dome antennas or a mix of dome and panel antennas.

Real-world coverage from this antenna depends on how much amplified signal the connected booster is feeding it, the size and layout of the room, and any physical obstructions like walls or furniture — not on outdoor signal strength, since that part of the job is handled entirely by the system’s outdoor antenna.
