2 Option: 720-4 Parallel Stacking Kit, 430-2 Stack-Over Kit, CN057 (2-Splitter Type)CD models x727, x720, x713A are Yagi antennas designed from a newconcept offering high gain and developed for use at ground stations requiringvertical polarization. This series has incorporated various new technicalfeatures that were first utilized in the VHF series of antennas. The spacingand length of elements has been selected so as to maximum gain enable topick up a weak signal with effective S/N ratio. The distance between thedriven element and the first director is very small, about Lambda, butexcellent gain is still achieved. The driven elements are covered with plasticin order to minimize the adverse effects of rain and snow on theperformance, thus the electrical characteristics are stable. Take x727 forinstance, forward gain obtained is 20dBsingle alone while obtain incomparablesuperior side rob of -20dB.

3 It is upgradable to 2 stack-over. The use ofhigh quality coaxial cable and high efficiency power splitters provide formaximum gain and feeder loss is negligible below All of the crossbrackets are made of a rugged, lightweight magnesium alloy. Model x713 isa single array of 13 elements while the x720 is an array of 18 elements and27 element for john Beams for 1200 MHzDesigned and Developed in Newly Innovated TechnologyHigh Gain, Low Noise, Low-Loss and Superior StabilityModelx12182x12304x1230-12x12504 x1250-1 Frequency (MHz)12001200120012001200No. of Element18 130 230 2 250 250 2 2 Forward Gain (dBi) / B Ratio (dB)2525252525 Power Capability (PEP/kW)150300600300600 Boom Length (m) Space (m) : : Radius (m) Diameter (mm)32 5048 6148 6148 6148 61 Wind Surface Area ( ) (kg) RotatorRC5-xRC5-xRC5-xRC5-xRC5-x All the models include the balun transformer, connector type: -N- Wind survival rating for allthemodelsisabove35m/s.

4 Option: Stack-Over Kit CN052, (2-Splitter Type), CN052-1 Stack-Over Kit for x1218 SingleCD x1218, x1230, x1250 series of antennas offering high gain inYagi type are designed through newly innovated technologies thatovercomed the difficulties in such a antennas own, 1200 MHz which isone of the highest frequency in amateur band, 1200 MHz. As it is amatter of common that the difficulties raised in this high frequencyantennas usually solve by use of LNA amplifier just mounted belowthe feed point in order to boost the gain and reduce noise this series of antenna alone overcome these problems byadapting our new technologies by carefully redesigning structures ofantenna, that gives superior beam pattern and F/B ratio together withselectivity. The spacing and length of elements has been selected soas to achieve the excellent gain is achieved.

5 The driven elementstogether with reflector and 1st director are covered with plastic inorder to minimize the adverse effects of rain and snow on theperformance, thus the electrical characteristics are stable. The use ofhigh quality coaxial cable and high efficiency power splitters providefor maximum gain and feeder loss is negligible. All of the crossbrackets are made of a rugged, lightweight magnesium x1218 is a single array of 18 elements while the x1230 is anarray of 30 element and 50 element for john Beams for 2400 MHzIncomparable beam Pattern and Superior GainLow-Loss, High Precision, High Stable and Wide ApplicationsModelx24272x2427 Frequency (MHz)24002400No. of Element2727 2 Forward Gain (dBi)2124F / B Ratio (dB)2525 Power Capability (PEP/kW)100200 Total Length (m) Space (m) Radius (m) Diameter (mm)48 6148 61 Wind Surface Area ( ) (kg) RotatorRC5-xRC5-xCD x2427 series is high performance all weather type Yagi beam antennas for microwave band.

6 The optimum element spacing andlength along with precisely determined alignment of each element used in this antenna along with discontinuance of using steel boomtubings offer the highest obtainable gain with comparable beam pattern and radiational efficiency. Incoupled with sharp beam pattern,it offers superior selectivity with high S/N ratio as to pick up aweak signal from among unpreferable band condition. The antennaunit is encapsuled with weather-resist plastic case so that theunit will not be affected by snow and rain etc. Hight quality ismaintained as a portion of electrical part in the unit is improved the performance by use of micro-wave strip circuit. All the models include the balun transformer, connector type: -N- Wind survival rating for all the models is above 35m/s. Option: Stack-Over Kit CN051 (2-Splitter Type)
