ART-920 consists of three components:

1. Bidirectional high frequency amplifier (HFA), connected to0 the remote antenna.
2. Power supply unit with operation mode display, installed near the base part of cordless phone.
3. Lead down cable.

ART-920 allowes to:

• Increase the communication range of cordless phone up to 20 km due to compensation of loss in lead down cable.
• Refuse from laying bulky and expensive cable between the base part of cordless phone and remote antenna.
