2 (MatchingstubandU-balunareused in CL6A). Excellent VSWR characteristics are common toall models across 50 to 51 MHz. The electrical performance isoutstanding and the mechanical construction is similar to thatused on large arrays for HF. All the models use high gradediecasting clamps and the booms and brackets are comparableto those of large size of long john BeamsHigh Gain, Superior Strength, Low-Loss, Wide Applications4x213 HModel2x209A4x209A2x211A4x211A2x2134x213 (for EME)Frequency (MHz)144144144144144144144No. of Element9 29 411 211 413 213 413 2 2 Forward Gain (dBi) / B Ratio (dB)20202025252526 Power Capability (PEP/kW)1212122 BoomLength (m) Length (m) Space (m) Radius (m) Mast Diameter (mm)48 6148 6148 6148 6148 6148 6148 61 Wind Surface Area ( ) (kg) RotatorRC5-xRC5-xRC5-xRC5A-xRC5-xRC5A-xR C5x, ERC5 All the models include balun standard, connector type -N- Wind survival rating of all the modes is above 35m/s.

3 Option: 209A-4 Parallel Stack Kit, 211A-4 Parallel Stack Kit, Stack-Over Kit CN053CD's each model of x209A, x211A, x213 series are Yagi beamantennasofferinghighgainfor is designedfor use at groundstations that requirevertical polarization. The spacing and length of the elementsused offer the highest obtainable gain and efficiency throughseveral field tests using EME communication and Sun are coveredwithplastic inorder to minimize the adverse effects or rain and snow on theperformance and thus the electrical characteristics are X209 Aconsists of 9elements while 9elements formodel X211 and 13 elements for X213.

4 Two or Four of thesemodels can be placed in parallel to forman array enable toadjust stacking space either narrow or wide length. CD powersplitter is used for impedance matching and high cableisusedforbetween the power splitter and the driven , the special construction of the boomprovidesfor minimal distortioninthe vertical of theboomareusedtoprevent are made of a lightweight, rugged stacking distance of each model is selected so as toprovide for maximumgain and high front to side ratio.
