The GP-2 Antenna is intended for operation as an external antenna for cordless telephones and wireless stations; provides extension of the communication range and improvement of the communication quality; possesses high gain and low Standing Wave Ratio (SWR), is compatible with ART-300, ART-325 amplifiers.
The GP-2 Antenna is manufactured in three frequency versions:
I
For the phones , adapted for using in Ukraine (SN-258 Delta, SN-358 SmART, SN-568, SN-868, SN-258, SN-358)
II
For the phones , adapted for using in Russia (SN-358 SmART, SN-868R, SN-358ULTRA)
III
For the phones SN-258 Delta, SN-258, SN-258 Plus
IV
For the phones SN-258 Delta, SN-258, SN-358

High reliability and good operating characteristics of the Antenna are achieved through:
Application of the matched circuits with low losses, insuring the wide-matching of the antenna with 50 ohm cable and low SWR;
Using the multi-section structure with the phase-leveling coils, which provides the high gain for both frequency bands and insures the effec-tiveness at high power levels;
Watertight design of the antenna, application of protective cover resis-tant to mechanical impact and aggressive environments — this en-ables to avoid SWR leaps due to the weather conditions.
