Kusankha mlongoti pa intaneti

Mukasankha satellite woyendetsa pa intaneti, muyenera kusankha “mbale” yoyenera. Kwenikweni, ndi zophweka. Kuti muchite izi, simuyenera kudziwa physics kapena formulas, ndipo palibe chifukwa chowerengera chilichonse. Ogulitsa azitha kusankha mlongoti woyenera wokhala ndi zida za satellite Internet.

Kusankha mlongoti wa TV

Ngati mukufuna kugula mbale ya satana pa TV yanu, ndiye kuti muyenera kuganizira kukula kwake. Parameter iyi ikugwirizana mwachindunji ndi kupindula kwa chipangizocho. Kukula kwake kudzakhala kokulirapo. Ngati kukula kwa mbale kuli kochepa kuposa komwe kumaloledwa kulandira transponder yomwe mukufuna, uthenga “palibe chizindikiro” udzawonekera pazenera. Chithunzicho chidzagawanika “m’mabwalo”, ndipo zomwezo zidzachitika ngati mlongoti sunayendetsedwe bwino ndi satellite. Kwa mphamvu yolandirira ma sateleti osiyanasiyana, ma diameter osiyanasiyana amafunikira (53 dbW – 0.6 m, 48 dbW – 0.8 m, 45 dbW – 1.0 m, 40 dbW – 1.5 m).

Ndi mbale iti ya satellite yomwe ndi yabwino kusankha pa intaneti ndi kanema wawayilesi

Tinyanga za Offset ndizoyenera kulandila TV ya satellite ndi intaneti. Ma mbale a Offset ndi asymmetric cutouts kuchokera ku paraboloid of revolution, momwe muli chowunikira. Cholinga cha chinthu ichi chili chotsika kuposa pakati pa geometric pa mlongoti womwewo. Malowa amachotsa mthunzi pamalo ofunikira a chakudya cha mlongoti, komanso nsanamira zake zothandizira. Izi zimawonjezera index yothandiza yogwiritsira ntchito ndi gawo lofanana lagalasi. Irradiator muzojambula zoterezi ili pansi kuposa pakati pa mphamvu yokoka ya mbale. Choncho, zimawonjezera kukhazikika kwa mlongoti mu mphepo yamkuntho. [id id mawu = “attach_3565” align = “aligncenter” wide = “624”]

Kusankha mlongoti popereka

Tinyanga tomwe timalandira chizindikiro kuchokera ku satana, monganso ma analogi awo, zimadalira mafunde omwe amachokera kunsanja zapansi. Ngati ili yofooka, ndiye kuti kuwulutsa kudzakhala kopanda khalidwe. Pachifukwa ichi, muyenera kuganizira mtunda wobwerezabwereza ndikugula amplifiers apadera. Komanso, musaiwale za nyengo. Pofuna kupewa zolakwika, antenna yopereka iyenera kusankhidwa, poganizira malamulo awa:

• kapangidwe ayenera kugwira ntchito pafupipafupi osiyanasiyana 300 – 3000 MHz;
• chiwombankhangacho chiyenera kukhala chofanana ndi mtunda wa nsanja ya pansi;
• zizindikiro za mphamvu ziyenera kukonzedwa kuti zigwire mafunde;
• kwa malo otseguka kapena nkhalango, zinthu zosiyanasiyana zimagulidwa.

Zindikirani! Kusankha mlongoti wachibale ndi mainchesi a deflector ndikosavuta. Ndikwabwino kugula chinthu chokhala ndi miyeso yotsatirayi: ngati wogwiritsa ntchito akuwonetsa 90 cm, mlongoti woyikidwa wa 1.2 metres upereka chisangalalo chabwino ngakhale nyengo yoyipa.

Momwe mungapachike ndikukhazikitsa mbale ya satellite?

Kuti muyike mbale ya satana kunyumba, mudzafunika zida zotsatirazi:

• chingwe chowonjezera chazitsulo 3;
• puncher kapena kubowola ndi kubowola kwa mainchesi ofunikira kukonza bulaketi ndi nangula kapena ma dowels;
• ma wrenches 13 mm ndi 10 mm kukula (makamaka awiri);
• Phillips screwdriver;
• nyundo;
• zomatira kapena zomangira pulasitiki.

Mukasonkhanitsa mlongoti, sungani bwino ma bolts, komanso musaiwale za ma washers. Muyenera kuwononga 2 multifeeds ku chotengera chosinthira . Imodzi imakhomeredwa kumanja, yachiwiri – kumanzere pamodzi ndi chosinthira. Sikoyenera kukoka mwamphamvu kwambiri. Zomwezo zimagwiranso ntchito pa phiri la antenna palokha.

Kugwiritsiridwa ntchito kotchuka kwa multifeed poika mbale ya satana kwa ma satelayiti atatu [/ mawu] Chovalacho chiyenera kukhazikitsidwa pakhoma. Kenako, muyenera kupachika mlongoti kuti ulozedwe kumwera kapena kumwera chakum’mawa. Pambuyo pake, muyenera kutambasula chingwe chowonjezera ndikugwirizanitsa TV mwachindunji ku chochunira kapena cholandila. Chirichonse, uku ndiko kutha kwa nkhaniyi. Pomaliza, tikhoza kunena kuti mtengo wa satellite mbale ukugwa. Posachedwapa aliyense adzatha kugula “mwanaalirenji” wotero ndikuwona njira zambiri zomwe mungasankhe. Kuchokera kwa kasitomala chinthu chimodzi chokha chimafunika – kusankha choyenera.
