Product Description

 

TV Digital Antenna DTMB High Gain Long Range Large Yagi For Outdoor

 

The Working Principle Of Yagi Antenna Is As Follows (Take Three Element Antenna As An Example): The Seeker Is Slightly Shorter Than Half Of The Wavelength, The Main Oscillator Is Equal To Half Of The Wavelength, The Reflector Is Slightly Longer Than Half Of The Wavelength, And The Spacing Between The Two Oscillators Is One Fourth Of The Wavelength. At This Time, The Inductor Is "Capacitive" To The Induced Signal, And The Current Is 90 ° Ahead Of The Voltage; The Electromagnetic Wave Induced By The Inductor Will Radiate To The Main Oscillator, And The Radiated Signal Will Lag 90 ° Behind The Signal Directly Arriving At The Main Oscillator From The Air After A Quarter Wavelength Journey, Just Offsetting The "Lead" Caused By The Front, And The Two Phases Are The Same, So The Signal Superposition Is Strengthened. The Reflector Is Slightly Longer Than Half Of The Wavelength And Is Inductive. The Current Lags 90 Degrees. In Addition, It Lags 90 Degrees In The Process Of Radiation To The Main Oscillator, Which Is 180 Degrees Different From The Signal Directly Added To The Main Oscillator From The Direction Of The Reflector. If One Direction Is Strengthened And The Other Direction Is Weakened, There Will Be Strong Directionality. The Same Is True For The Launch State And The Action Process

The Use Of Yagi Antenna ?

Among The Radio Waves Of The Same Frequency In All Different Directions Arriving At The Antenna, The Radio Wave With Relatively Strong Gain And No Strong Interference Of The Same Frequency In The Adjacent Angle Is Selected And Transmitted To The Receiving Device.

The Straight Plate Machine Can Be Disassembled, And A Small Copper Wire About 10cm Long Can Be Welded At The Antenna Contact. Without Welding Tools, It Can Be Tied To The Contact Foot Of The Antenna, Stretched Out From The Casing And Fixed. Smart Machine Download A Software Called "Base Station Lock", The Local Signal Is Poor, Suggest To Buy A Mobile Phone Signal Intensifier, Cheap About 200 Yuan.

Yagi Antenna Is Really Easy To Use. It Has Good Directivity And Higher Gain Than Dipole Antenna. It Is Very Effective For Direction Finding And Long Distance Communication. If It Is Equipped With Elevation And Azimuth Rotation Control Devices, It Can Also Contact Radio Stations In All Directions, Including Spacecraft, At Will. This Feeling Is Not Available From The Vertical Antenna.
