TV antenna ngezandla zakho - umda ukhetho izinto kunye ngeso

Kwimarike kukho imizekelo emininzi eriyali TV kbavelisi ezahlukeneyo. View phantse yonke gqitha, yaye iinkcukacha ezidweliswe wavebands ukuqinisekisa ulwamkelo ngamandla onke amabanga, inzuzo kunye nezinye iparameters ukuba umntu ngaphandle zemfundo ezizodwa okanye uqeqesho bangathethi kwanto.

Ngaba imizekelo lo mqondiso kwezixhobo ngeendlela ezahlukeneyo, kodwa ngokuqhelekileyo lukhulu. Ukuba umsebenzi kukubonelela esemgangathweni imifanekiso yakho ekhaya TV, kwaye ngokupheleleyo nokuzithemba ngenxa yokuba i-eriyali kukuthi sebe, kungaba nenzuzo ukufumana gizmo kwaye uyifake phezu kwendlu.

Noko ke, ngokufuthi kwimeko enjalo: indawo eqhelekileyo ipoma kunye nendlu encinane, apho kubonakala abanini kuphela ehlotyeni, uze kuphela ngeempela-veki. Kwaye ngoko phezu kophahla - saa esimenyezelayo, leyo yazisa ebala wengingqi ezisemaphandleni ekuhendweni. Ekufuneka sizithengile ukufaka kulo entsonkothileyo yaye kubize nkqubo?

Kubalulekile ukuqonda ukuba yintoni na umgaqo osebenza kuyo eriyali.

Nganye yefrikhwensi ingqamana ubude ukujikeleza kwalo resonant oscillatory, eyinxenye ye-eriyali, nangona kunjalo, iziphaluka ezininzi ezahlukeneyo iya kwi-eriyali uqwalaselo, kuya kuba efanayo impendulo frequency.

Imfuneko yesibini - amandla kwesakhiwo. antenna yethu TV - lwangaphandle, ngoko ukumelana ukumelana nomoya kunye yemozulu. Xa ukubanjwa ukuba intonga kufuneka kusetyenziswe izinto ezifana engqindilili PCB kunye metal yamasango.

Kukho iinketho esiqinisekisiweyo, nto ezo antenna umabonwakude ngezandla zakho - umzekelo, inkqubo eziveliswe signalman emangalisayo Soviet Kharchenko. Kodwa ke inqanaba uqeqesho lobugcisa kule meko kufuneka ibe phezulu ngokwaneleyo. A isakhiwo obulula yenziwe ngomthi kunye neengcingo, akukho ixesha elide kakhulu, kodwa kulula ukuba ukudlala kwakhona xa kuthe ukusilela.
