HELIOS's GSM1800MHz Trunk Amplifier Series is to provide in-building radio coverage in a flexible and efficient way. Among the things with reference to the design it can be difficult to spread coverage all the way into side isles, narrow hallways, and several statuses, combined with different building materials. Moreover, if there are many people constantly moving, for instance in shopping malls, and the demand for coverage varies from one spot to another as well as during the day and during the week, satisfying the growing demand for capacity becomes a challenge. The same status can be occurred in some villa group, Subway, Speedway, etc. So the repeater can gives you the optimal solution.

Application: In-building, Subway stations, Basement, Tunnels, Shopping malls, Speedway, Underground parking etc.

Features:

1. Applicable to amplify and extend signals of GSM1800MHz indoor coverage system
2. Improved system noise figure and sensitivity, no interference to base station
3. High out band rejection, excellent intermodulation and spurious emissions
4. High gain linear power amplifier technique, with reliable performance
5. Compact design, water-resistant, weather-proof and antisepticise
6. Applicable to indoor coverage sytem in huge, medium building.
