Mini Repeater (BDA) High Performances High Selectivity
The EMTS Telecom Services Mini-Repeater (MR) is a Bi-Directional Amplifier; it provides an excellent solution to the problem of poor signal coverage. The MR amplifies the signals from mobile phones and base stations and can be used in 'dead zones' where service is poor. Typical installations can be in basements, offices, restaurants, hotels, apartments, parking lots, etc., initially blocked by structures and limited obstacles or coverage. Easy installation, lightweight Design, and comfortable use make the EMTS Mini-Repeater a cost-effective and practical solution for extending signal coverage. An IMOP (Isolation Measurement – Oscillation Prevention) mechanism designed to prevent oscillation due to low or marginal isolation between donor and service antennas.
EMTS Telecom Services Ltd. offers a comprehensive portfolio of enhanced coverage solutions for the Wireless
