Base antenna amplifier ART-325 to extend communication range of cordless phones of "RCS" SmART-358, "SENAO" SN-258, SN-258 Plus, SN-358 by 3-7 times (supplied in corresponding modifications). It’s most effective to use ART-325 in conjunction with subscriber amplifiers ART-300М2, ART-300М3, ART-358 and with subscriber stations SN-258 Line, SN-358 Line, SN-258Plus Line.
ART-325 application provides: • Communication range extension by 3—7 times as compared to standard variant. • Possibility not to use bulky and expensive low loss cable between phone base and external antenna. • Longer antenna life when applied in winter conditions: much less condensation and antenna icing thanks to heating by amplifier. Amplifier set consists of: 1. Two-way RF amplifier with circuit for output power, SWR and temperature control (connected directly to antenna body). 2. Power supply with amplifier working modes indication – installed near phone base unit. 3. Lead down cable. Amplifier ART-325 is produced in several frequency variant types. «SENAO» phone model compliance to amplifier’s frequency range: SN-258 PLUS 262/388 MHz SN-258 262/388 MHz 264/390 MHz SN-358 264/390 MHz 268/394 MHz
For telephones with index U (for example, SN-358 U) use ART-325 amplifier of frequency range 254/380 MHz.
