Electronic article surveillance – 8.2 MHz
With a radio-frequency article surveillance a transmitter generates a zone, in which not deactivated etiquettes or not removed hard etiquettes (tags) are recognized by the system. The transmitter sends out constantly a RF signal with a certain frequency (RF 8.2 MHz).
If a not deactivated etiquette or a hard etiquette (tag) is brought now into this field, a coil which is placed right inside the tag is charged and sends out a signal which is identified by the receiver and releases therefore the alarm.
EAS systems with RF technology can be delivered in the many different variations. For small shops or shops with a small entrance area (up to 100-120 cm) an inexpensive, but extremely powerful mono antenna is often sufficient. To protect larger distances up to 120-160 cm we recommend 2 antenna systems with an active broadcasting antenna and a receiver antenna as well as a second passive antenna in addition to a mono antenna. With even bigger distances between 180 and 230-250 cm article protection system cover the whole area completely only with 2 antennas. Here both antennas are equipped with a special electronics to covers the big distances well.
For our RF systems, which we deliver and install mainly with 8.2 MHz, we have a big choice on hard etiquettes (tags), detachers and other security accessories in our assortment. You find the complete range right here on our web page.

Electronic article surveillance systems RF 8.2 MHz – Installation
The following factors should be taken into consideration before the installation of RF systems:
- Metallic doors: Antennas should be put approx. 0.5 – 1.0 meters away from the entrance area.
- Electric cables above the article protection disturb the antenna sometimes
- Other RF systems cuse interference and disturb the systeme. Here the frequency must be adjusted during installation.
- Strong electric systems (cash registers, …) in the immediate surrounding area of the article protection should be avoided
- Mono antennas protect in both directions, hence, a bigger area must remain on both sides of the antenna without security tags.
