Do you have a corrugated roof at your house, warehouse or factory? This can have a very negative effect on your cellphone signal and data speed. An outdoor antenna can make all the difference as this customer in Johannesburg saw when installing an XPOL-6 Antenna on their roof.


Do you have a corrugated roof at your #house#warehouse or #factory? Combine this with thicker walls and metal reinforcing, you probably experience bad cell phone signal.

4G, LTE, and 5G signals are radio frequency waves. Like all radio waves (cellular, WiFi, AM/FM radio, satellite, etc.), obstructions can weaken and obliterate cell signal. This is especially true for 5G’s high frequencies.

4.1     How do we measure cellphone or data signal?

People often look at the bars on their phone to see how strong their signal is. Although bars are an indication it is often a subjective measure. The network operators can decide how much signal 2, 3 or full bars of signal is.


An objective measure is to look at the dBm of your signal. Signal strength ranges from -50 dBm (great signal) to -120 dBm (dead zone). The closer you are to -50 dBm, the better your signal.

The increase (gain) or decrease (loss) of signal strength is measured in dB (decibels). It is important to note that every ± 3 dB means gaining or losing double the power.


Materials like corrugated or metal roof takes away dB from the signal trying to enter your home or office. The one way to solve this is to bring the signal outside, inside the house, and an outdoor antenna is an excellent way to do that.

4.2     An outdoor antenna

We have often shown theory, and with 1000s of actual “indoor vs outdoor” measurements that there is roughly 10 to 20 dB signal increase SIMPLY by moving your antenna OUTDOORS. This can even be found when mounting the antenna against the inside of a clear window when the window faces in the direction of a mobile tower.

4.3     Example

Bradwyn Goliath had a customer in the older part of #Johannesburg, that stays  in a house with thick walls and a corrugated roof. The customer had NO signal inside the house when using his Huawei-B535-932A Router.

Inteto Connect installed the #Poynting XPOL-6 Antenna with the HUAWEI Router, and their internet problems were solved. From No Signal the customer now had a download speed of 𝟯𝟴.𝟵 𝗠𝗯𝗽𝘀!

The XPOL-6 is a Cross-polarised, high-gain antenna ideal for LTE applications. With this antenna you get:

  • Futureproof wideband LTE antenna and Wi-Fi operational frequencies
  • Backwards compatible with 2G and 3G technologies
  • Two antennas in one enclosure for optimal LTE performance
  • 2X2 MIMO LTE/4G antenna
  • Increased connectivity stability
