Wilson International 12" Magnetic Mount Antenna with SMA Male Connector & 12.5' Coax Cable (311703)

Outside Antennas

The right outside antenna comes down to three things: how strong your signal is outside the building, the terrain around you, and which direction your cell towers are in. The stronger the antenna, the more signal your amplifier has to work with, and the more coverage you get inside.

• Omni Antenna: Receives signal from every direction with 4 dB of gain, and there's nothing to aim. Choose it when your outside signal is strong enough that you don't need extra gain, or when you're in a valley or hilly area where the signal bounces around a lot. Its wider, lower-gain pattern handles bouncing signal better than any other option here.
• High Gain Omni Antenna: Receives from every direction like the standard Omni, with up to 9 dB of gain instead of 4. This is the right choice for most buildings. You get close to the Yagi's power without having to aim anything, and it works when your carriers' towers sit in different directions.
• Yagi Antenna: A directional antenna with 10 dB of gain. Choose it when your signal is weak and comes mostly from one direction. You aim it at the tower, and its 75 degree view of the horizon means the aim doesn't have to be perfect.
• High Gain LPDA Antenna: The strongest of the four at 11 to 13 dB. Choose it when your outside signal is very weak. It needs a clear line of sight to the tower and careful aiming, so it takes the most work to set up, and it delivers the most coverage once it's aimed correctly.

Inside Antennas

The right inside antennas depend on your space. A typical floor with standard-height or drop ceilings usually calls for a dome antenna. Higher ceilings, multiple floors, or a spot you want to aim signal at call for a panel.

• Ultra-Thin Dome Antenna: This is what we usually recommend. It mounts to the ceiling and broadcasts in a circle around it, delivers more gain than the standard Dome at 4 to 6 dBi, and sits nearly flush so it blends into the ceiling.
• Dome Antenna: The standard version of the ceiling dome at 2 to 5 dBi. It costs a little less than the Ultra-Thin, covers a little less, and sticks out from the ceiling more.
• Panel Antenna: The most versatile of the three at 7 to 10 dBi. It's directional, so it sends signal where you point it instead of in a circle. Choose it for high ceilings, for covering two floors at once in a home (it broadcasts through the floor when aimed that way), for long narrow spaces like hallways, or when you're targeting one area and don't want signal going the other direction.

How Many Inside Antennas Do You Need?

Start with the square footage you need covered. In spaces with walls, one inside antenna covers 750 to 1,500 square feet. In open layouts, one covers 1,500 to 2,500. Divide your space by those numbers and you have your antenna count. Most offices end up needing more than one antenna per floor, and that's normal.
