1 HF long john BeamsMaximumGain Theoretically Physically Obtain and Sharp BeamPatternMeet For Those Seeking for MaximumPerformace, Rugged StructureThese are high gain antennas designed to offer the highest obtainable gain manufactured under high tolerance specifications tomeet the customers seeking the best without any of the models have an optimumlength and a spacing ofelements so as to derive maximumattainable capabilities theoretically. The CD Yagi Beams are designed to simulate those forprofessional applications and are made of aluminumcomponents with highest quality to strict specifications and clamps made ofmagnesiumalloy through high precision machining.

2 Each of the models is provided with a high-power balun indispensable to aYagi beamsystemas well as a unique hairpin stub in order to ensure optimumtransmission of high frequency energy at lowstanding wave ratio (VSWR). Thus, the CDYagi Beams are rugged and exceptional antennas manufactured on the basis ofexcellent technology in design and (MHz) / / type7-2 Band type777No. of 7 9 Forward Gain (dBi) 8 16F / B Ratio (dB) 20 Power Capability PEP (kW)4444444 BoomLength (m) Length (m) Radius (m) Diameter (mm)60 7760 7748 6148 6160 7760 7760 77 Wind Surface Area ( ) (kg) RotatorRC10 SRC10 SRC5A-xRC5B-xRC5B-3RC5B-3RC10 SModelCY302CY303CL30CL20CL20 DXCL20 DXXF requency (MHz)101010141414No.
