Yagi Antenna, seyakajairwa Autental antenna, inoshandiswa zvakanyanya muHF, VHF uye UHF mabhendi. Yagi ndeyekupedzisira antenna iyo ine anoshanda oscillator (kazhinji yakafetwa oscillator), anenge asingarapi paincrestor uye nhamba yehuwandu hwepasiti yakarongedzerwa mukufananidza.
Pane zvinhu zvakawanda zvine chekuita nekuita kweYagi Antenna, uye kugadziridzwa kweYagi Antenna kunonyanya kuoma kupfuura mamwe antennas. Madziro maviri eAntenna anonyanya kugadziriswa: Resonant Frequency uye akamira wave ratio. Ndokunge, iyo yekugara yekugara yeAntenna yakagadziridzwa kutenderedza 435mhz, uye yakamira mota yeiyo antenna iri pedyo ne1 sezvinobvira.
Gadza iyo antenna nezve 1.5m kubva pasi, batanidza iyo yekumira mita uye kutanga kuyerwa. Kuti uderedze zvikanganiso zvekuyera, tambo inobatanidza iyo antenna kune yakamira wave mita uye redhiyo kune yakamira mita mita inofanirwa kunge iri pfupi sezvinobvira. Nzvimbo nhatu dzinogona kugadziridzwa: Iko kugona kweiyo trimmer capacitor, chinzvimbo chedunhu pfupi yedunhu uye kureba kweiyo inoshanda OSCICLATOR. Iyo chaiyo yekugadzirisa matanho ari seinotevera:
.
.
.
. Kana iyo frequency yakanyanya kukwirira kana yakaderera, iyo yekukwazisa masaya inogona kuyerwa zvakare nekutsiva iyo inoshanda oscilllator mamirimita akareba kana kupfupi;
.
Kana iyo antenna yakagadziridzwa, gadzirisa imwe nzvimbo panguva, kuti zvive nyore kuwana mutemo wekuchinja. Nekuda kwekutanga kwekushanda frequency, iyo amplitude yekugadziriswa haina kuwandisa. Semuenzaniso, iyo yakagadziridzwa kugona kweiyo tuning capacitor yakabatana mune ye γ bar iri anenge 3 ~ Uye zvakare, zvakawanda zvinhu zvakadai sekureba kwebhari uye chinzvimbo chengarava chichavawo chine chekuita nekuyerwa kwekuyerwa kwamasere, izvo zvinofanirwa kutariswa mukugadzirisa maitiro.
