Atmas Introduces a Passive Shelter Antenna Approved for Civil Defence Shelters

Passive indoor antenna installed in civil defence shelter

The passive indoor antenna is a device that reproduces signals without its own power source. It receives, transmits, and transmits signals from the outside of the enclosure to the inside and vice versa.

In practice, a passive repeater usually consists of two antennas, one placed outside the shelter and the other inside. The antennas are connected to each other by a cable that does not require an external power source.

When designing and building shelters, several technical and safety-related issues must be taken into account, one of the key ones being the functionality of communication connections inside the shelter.

The passive antenna for civil defense allows radio and mobile phone signals to pass through concrete walls and metal structures, thus enabling communication while in shelter.

Our passive antenna also allows you to use mobile data and access the internet. Instant messaging apps that use mobile data, such as WhatsApp and FaceTime, will work.
