Where To Buy

The Indoor Board 75 is strong, stylish, and can be easily mounted on a wall, just like a picture frame or TV. The Indoor Board is our go-to antenna for most home signal boosters.

The Indoor Board is a simple, flat, white indoor panel antenna. If you saw it on someone’s wall, you might wonder what it is. It’s not designed to stand out or be a work of art – it's meant to be stylishly unassuming. The ridiculous “75” part of its name denotes it being 75-ohm impedance, to separate it from the regular, 50-ohm Indoor Board.

What The Indoor Board REALLY does is deliver boosted cellular signal. It radiates in a 60-75° directional beam, making them excellent for hallways, long rooms, high ceilings, but most importantly, wherever you need stronger signal.

Due to its easy installation, the Indoor Board is our most versatile indoor antenna offering, and where you don’t have reliable signal, you can mount it up. It will provide up to +8 dBi of gain at the point of capture.

This is an ultra-high quality panel antenna for broadcasting cellular signal. There are two variants. This is the 75 Ohm with F-Female termination variant. Choose the one you need for your cell phone signal booster system. 75-Ohm has higher loss but is easier to install. The Indoor Board 75 will provide up to +8 dBi of gain at the point of broadcast.

The Indoor Board 75 antenna works with all cell phone signal boosters (weBoost, SureCall, Cel-Fi, etc.), and cellular hotspots (Pepwave, MoFi, Netgear Nighthawk, etc).

You have questions. We have answers.

When Should I Buy the Indoor Board 75?

The Indoor Board 75 is a strong, directional indoor panel antenna designed for wall-mounting. It’s more powerful than the omnidirectional options (The Cowboy and The Rondo). Its best use is in relatively small rooms – we recommend The Cowboy or Rondo in wide open spaces. If you have a very weak system, or a lot of small rooms, The Indoor Board 75 is your best indoor antenna option.

Bear in mind that there are two varieties of The Indoor Board: a 50 Ohm antenna with N-Female termination, and a 75 Ohm antenna with F-Female termination. This is the 75 Ohm version. Choose the one that works best with the signal booster you are using.

How Many Indoor Antennas Should I Buy?

Indoor antennas effectively expand your antenna coverage, so buying more with a powerful system makes a lot of sense. The specific number is something you’ll need to figure out yourself – but here are some relevant questions to ask:

  • Is my outside signal weak? Weak outdoor signal makes it harder to add more antennas to a system because you lose some signal every time you add additional antennas.
  • Where do I most need enhanced cellular? Is it more than one place? Are these places near each other? If yes, getting another antenna is a no-brainer.
What Kinds of Signal Does the Indoor Board 75 Broadcast? What Radio Bandwidths?

The Indoor Board broadcasts any signal between the 698-2700 MHz bandwidths. That includes all 4G/LTE/3G cellular signal. This covers all US carriers (AT&T, T-Mobile, Verizon, U.S. Cellular and more), Canadian carriers (Rogers, Bell, Telus, more), Mexican carriers (Telcel, Movistar, AT&T Mexico), and far more.

However, all this is dependent on what your donor (outdoor) antenna(s) is capturing. While The Indoor Board 75 is our most powerful indoor antenna at point of broadcast, it cannot create high-quality or strong signal on its own.

What Does dB Mean? What About Gain?

dB refers to the power gain of the antenna, and the higher the number, the more powerful the antenna. As dB is measured on a logarithmic scale, every +3 dB represents a doubling of the power gain.

Will the Indoor Board Work with My Carrier?

The Indoor Board 75 will work on any US or Canadian carrier, as well as most cellular carriers worldwide. If you are not sure your country’s carrier will work with The Indoor Board 75, verify whether your service falls within the 698-2700 MHz bandwidth, and if so, it will work.
