Choosing the Right Conference Room Jammer for Small Spaces


Conference room jammers are essential devices used to block signals in small meeting spaces. With various options available in the market, it is important to consider whether to choose a conference room jammer with built-in or external antennas. This article aims to explore the advantages and disadvantages of each option to help readers make an informed decision.

Subtitle: Choosing the Right Option for Small Meeting Spaces

When it comes to small conference rooms, there are two main types of conference room jammers available in the market: those with built-in antennas and those with external antennas. While both options serve the same purpose, there are certain factors to consider before making a decision.

External Antennas:

For relatively small meeting spaces, conference room jammers with external antennas can be a suitable choice. These jammers often come at a lower price point, making them more economical. However, it is important to note that the quality and craftsmanship of these jammers may vary. Some external antenna jammers even have antennas of different lengths, which can affect the overall aesthetic of the conference room. Additionally, some models have exposed cooling fans that generate noise during operation, which can disrupt the meeting environment.

To mitigate the noise issue, users can disconnect the cooling fan if the meeting duration is within an hour. However, for longer meetings, it is advisable to opt for conference room jammers with low noise levels. This ensures a peaceful and orderly meeting environment.

Built-in Antennas:

On the other hand, conference room jammers with built-in antennas offer a more aesthetically pleasing solution. With the antennas completely hidden from view, these jammers provide a sleek and professional appearance. Moreover, the built-in antennas offer protection against accidental damage during transportation, preventing them from detaching and rendering the device unusable. This is particularly important as continued use of a jammer with a detached antenna can lead to the RF module burning out.

Furthermore, the convenience of transferring conference room jammers with built-in antennas cannot be overlooked. These jammers feature a convenient groove handle on the back, allowing for easy transportation without the risk of antenna detachment. This ensures the uninterrupted and reliable use of the jammer in different meeting spaces.


In conclusion, the choice between built-in and external antennas for conference room jammers depends on various factors. While external antenna jammers may be more cost-effective, they come with potential drawbacks such as inconsistent antenna lengths and noise from exposed cooling fans. On the other hand, conference room jammers with built-in antennas offer a more aesthetically pleasing solution and provide added protection during transportation. Ultimately, it is recommended to choose conference room jammers with built-in antennas for their convenience, reliability, and professional appearance.
