Our VHF yagi dual stacked antenna, UHF dual stacked yagi antenna and microwave dual stacked yagi antenna design reflects innovative modern antenna construction. The mounting hardware of VHF UHF dual stacked yagi antenna is made of type 316 marine grade stainless steel. Antenna Experts also manufactures dual stacked yagi with reflector for digital TV gap-filler application for 470-860 MHz frequency band.
Special mounting hardware permit to mount the vhf uhf dual stacked yagi antenna either Horizontal or Vertical polarization. These dual stacked yagi antenna are highly directional, comes factory tuned and does not require any field adjustment. The feed point radiator of dual stacked yagi antenna is enclosed in a Nylon housing designed to protect against severe environmental conditions and minimize pattern distortion.
Antenna Experts ADY-127 aviation band dual stacked yagi antenna system is highly suitable as base station antennas for ATC sites where longer communication range is required to cover the particular sector of Flight Information Region (FIR) like narrow but long strip if stacked side-by-side or Oceanic Information Region (OIC) of a bay if stacked vertically. The VHF aviation band dual stacked array is consisting of 2 yagi antenna, supplied with a solid air cored 2 way power splitter/combiner and 2 low loss phasing harness cables.
Antenna Experts manufactures YRD series of dual stacked yagi antennas for wireless digital TV gap-filler application. The YRD-575 dual stacked yagi with reflector is highly suitable for vertical polarized power repeater application and low-power horizontal polarized digital TV gap-filler application from channel 27-40 frequency 518-630MHz band. Wireless digital TV gap-filler (Re-emitter) provides effective solutions for blind zones and shadowy zones. Yagi with reflector is mainly used in expressways, railways, tunnels, country sides, homes, multi-stories buildings and elevators.
The unique design of Antenna Experts dual stacked yagi antenna feed which works as matching device to keep the VSWR low resulting in increased efficiency of the yagi with reflector. The mounting hardware supplied facilitates mounting on either vertical or horizontal members. The grid reflector supplied in two segments for easy of shipping and handling. The yagi with reflector is highly suitable where high front to back ratio and high side lobe suppression are required.
The Dual Stacked Yagi antennas are designed for rear mounting and or with center mounting option are supplied with 2 way power splitter/combiner, phasing harness cables and stacking pipe. These Dual stacked antennas are designed to stacked and fed in phase with supplied matching phasing harness cable for increased gain to 3 dBi. The dual stacked yagi antenna can be stacked either in horizontally or in vertically to control the beam-width in desired plane.
Antenna Experts ADY-550 and ADY-650 dual stacked yagi antennas are highly suitable for technical requirements for Remote Rural Broadband Systems (RRBS) operating in the bands 512-608 MHz and 614-698 MHz (TV channels 21 to 51). For higher gain these antennas can supplied with trough reflector to increase the front to back ratio and minimize the side lobes. The trough reflector is supplied in two segments for easy of shipping and handling and can be assembled in less than 2 minutes with simple hand tools.
Antenna Experts dual stacked yagi antenna with reflector uses special feed which eliminates the use of folded dipole. The dual stacked yagi antenna with reflector is supplied with N termination fixed on the driven element. The grid reflector increases the front to back ratio and reduced the side lobe level. This directional yagi antenna comes factory tuned and does not require any field adjustment. The small surface area on the yagi antenna minimizes wind resistance and conserves tower loading capacity.
Radiating elements, supporting booms and adjoining metal castings of dual stacked yagi antenna have been constructed in 6063T6 ultra corrosion resistant architectural anodized aluminium alloys to prevent corrosion. Our VHF UHF dual stacked yagi antenna is supplied with powder coating finish to protect the yagi antenna further from severe environmental conditions.
The VHF dual stacked yagi antennas when packed, comes with elements removed from the antenna boom for ease of packing and transportation where as the UHF Yagi Antennas comes in pre-assembled design with permanently fixed elements in to the support boom. The antenna is supplied with olive green MIL color finish. Other customized housing/radome color can also be supplied on request
Antenna Experts dual stacked yagi antenna design reflects innovative modern antenna construction. The unique design of the yagi antenna feed which works as matching device to keep the VSWR low resulting in increased efficiency of the yagi antenna. Cylindrical radome enclosure is used in microwave yagi antenna for low wind loading and for minimal effect of ice formation on the high power broad band antenna operation as well as providing an aesthetically pleasing appearance
Antenna Experts Microwave Dual Stacked Yagi antenna is completely protected within a high-tech ruggedized radome which is made of high strength fiber glass encosure to ensure survivability in the worst environments conditions. The heavy duty fiber glass enclosure has excellent transparency for RF signals and enough strength to withstand more than specified wind loads.
