CB Radio - Kodi Muyenera Kugwiritsa Ntchito Masiku Ano? Ubwino wa wailesi ya CB ndi chiyani?

Kupezeka kwakukulu kwa mafoni a m'manja ndi intaneti opanda zingwe kwatanthauza kuti wailesi ya CB yalowa m'malo ndi kugwiritsa ntchito mafoni. Komabe, pali madalaivala (makamaka omwe nthawi zambiri amayendetsa mtunda wautali) omwe amakhalabe owona pa chisankhochi. Kodi ndi bwino kugula chipangizo choterocho? Kodi kukhazikitsa iwo? Dziwani zambiri za CB Antennas!

CB antennas ndi chiyambi cha kuyankhulana opanda zingwe

Mwinamwake aliyense m'moyo wake anamva za walkie-talkies. Ana ankakonda kwambiri kusewera ndi zidazi, koma izi si zokhazo zomwe zimagwiritsidwa ntchito popanga izi. N’chifukwa chiyani tikutchula zimenezi? Mlengi wake anapanganso wailesi ya CB (yotchedwa "CB wailesi"). Uyu ndi Alfred Gross, yemwe amakonda kwambiri zopanga zozikidwa pa kulumikizana opanda zingwe. Mayankho omwe adapereka patent adawonetsa kuyambika kwa nthawi yatsopano pankhani yolumikizirana opanda zingwe.

CB Antenna and Receiver - Kodi zida zoyankhulirana zimagwira ntchito bwanji?

Zofunikira kwambiri zomwe zimapangitsa kuti wailesi ya CB igwire ntchito ndi:

• kusinthasintha;
• pafupipafupi.

Yoyamba mwa izi itha kugawidwa mu AM ndi FM modulation. Kusiyana kwakukulu pakati pa ziwirizi ndi khalidwe la chizindikiro. Zidzakhala zosalala kwambiri pamitundu yosiyanasiyana ya FM.

Nthawi zambiri, ndi mafunde a electromagnetic osiyanasiyana. Pogwiritsa ntchito chipangizo choyankhulirana chagalimoto m'dziko lathu, njira 40 zasungidwa, zomwe zili pakati pa 26,960 MHz mpaka 27,410 MHz. M’kati mwake, anagaŵidwa ndi kuikidwa chizindikiro mogwirizana ndi miyezo yovomerezedwa. Chifukwa cha izi, kulumikizana kumapangidwa.

CB wailesi - zida zofunika

Kuchokera pamawonedwe aukadaulo, zotsatirazi ndizofunikira kuti makinawo agwire bwino ntchito:

• mlongoti;
• wolandila (wailesi foni).

Ma CB antennas amapezeka mosiyanasiyana komanso kutalika kwake. Pali lamulo losavuta: kutalikirapo kwa mlongoti, kumapangitsanso kuchuluka kwa siginecha yomwe imatha kuyipanga. Komabe, chinsinsi ndikukhazikitsa zonse, chifukwa popanda iyo, wailesi ya CB, ngakhale ndi mlongoti wautali kwambiri, sigwira ntchito bwino.

Purezidenti, Midland Alan, Yosan - opanga olandila CB

Pali opanga angapo otsogola pamsika wamagalimoto olumikizirana. Izi zikuphatikizapo:

• Midland Alan;
• Albrecht;
• M-Tech;
• Pni;
• Purezidenti;
• Lafayette;
• Yosan.

Chinsinsi cha kugwira ntchito kwa chipangizochi ndikusintha kwake, koma osati kokha. Ndikofunikiranso kwambiri kukhala ndi njira yochepetsera phokoso, zolumikizira zowonjezera ndikugwira ntchito mu AM kapena FM modulation.

CB radio antennas - kutalika kofala kwambiri

Mukudziwa kale kuti pamlingo wokulirapo, muyenera kuyang'ana mlongoti wautali kwambiri. Komabe, wailesi ya CB yokhala ndi mlongoti wautali wa 150 cm imatha kupanga kuyendetsa mzinda kukhala ntchito yeniyeni. Zosankha zazikuluzikulu zili pamtunda wa masentimita 60-130. Palinso ma antenna omwe amagwira ntchito zambiri, omwe amakhalanso ndi udindo wolandira chizindikiro cha wailesi, chida chopanda manja (maikolofoni) ndi ntchito ya wailesi ya CB. Nthawi zambiri amakhala pafupifupi 50 cm.

CB radio antenna - mitundu yokweza

Mutha kusankha imodzi mwa njira ziwiri zoyikira mlongoti wa CB mgalimoto yanu:

• maginito;
• mosalekeza.

Yoyamba nthawi zambiri imasankhidwa ndi madalaivala chifukwa cha kuyenda. Padenga la galimoto kapena malo ena a thupi lathyathyathya, muyenera kuyika maziko a maginito ndi momwe mlongoti umamangiriridwa. Mwanjira iyi, wailesi ya CB imatha kusonkhanitsa ma signature mokhazikika. Njira ina ndi zitsanzo zomwe zimayikidwa kwamuyaya m'magalimoto. Komabe, yankho ili ndi la madalaivala otsimikiza omwe safunikira kuchotsa mlongoti m'galimoto.

Momwe mungasankhire tinyanga ta CB pa wailesi?

Kuphatikiza pa izi, magawo ena angapo ndiofunikira. Musanagule, onetsetsani kuti mtundu uwu uli ndi mtundu wanji. Monga lamulo, kwa mzinda, makope ang'onoang'ono ndi okwanira, okhoza kusonkhanitsa chizindikiro mkati mwa utali wa makilomita 5. Nkhani ina ndikupindula kwa mlongoti (kuyezedwa mu dBi). Nthawi zambiri tinyanga timakhala ndi parameter iyi kuyambira +1 mpaka +6 dBi. Inde, ndi bwino kwambiri. Chinthu china choyenera kuchiganizira ndi nkhaniyo. Khalani ndi zitsulo zosapanga dzimbiri. Adzakhala osagwirizana ndi chinyezi.

Wailesi ya CB - zomwe mungagule pagalimoto

Kubetcherana pa mtundu wolandila woyesedwa ndi ogwiritsa ntchito ena. Osamangotsatira malingaliro omwe amaikidwa m'masitolo apaintaneti, komanso yang'anani zambiri m'mabwalo apaintaneti. Wailesi ya CB yomwe mukufuna kugula (pokhapokha ili yotsika mtengo yochokera Kum'mawa) imafotokozedwa bwino ndi ogwiritsa ntchito. Yatsani kuchepetsa phokoso la ASQ ndikuwonjezera RF. Ndi zinthu izi, mudzatha kuthetsa phokoso lalikulu lakumbuyo ndi zokambirana. Simufunikira zida zapamwamba kwambiri. Yang'ananinso chitsanzo chokhala ndi njira ya NB/ANL kuti muchotse phokoso pamakina amagetsi agalimoto.

Wailesi ya CB - AM kapena FM?

Pankhani yosankha wolandila, m'pofunikanso kuyankha funso lokhudza mtundu wa kusinthasintha. Poyambirira, tidanena kuti mitundu yokhala ndi ma module a FM imafalitsa chizindikiro "choyeretsa". Komabe, m'dziko lathu, makope ambiri a AM amagulitsidwa, ndipo ena amathandizira FM. Mukangoyendetsa kunyumba, wailesi ya CB AM ikwanira. Komabe, pamaulendo okhazikika akunja, kusinthasintha kwa FM kumatha kufunikira.

Kodi mungakhazikitse bwanji mlongoti wa CB?

Kuwongolera kwachitsanzo kuyenera kuganizira za galimoto yeniyeni ndi malo osonkhana. Chifukwa chake, tinyanga tating'onoting'ono tochotsa m'manja sizigwira ntchito nthawi zonse ngati malo awo asinthidwa kwambiri. Kumbukirani kukhala ndi mita ya SWR pafupi ndikulumikiza ndi wolandila. Wailesi ya CB iyenera kuyimitsidwa kutali ndi mizere yamagetsi okwera kwambiri. Kodi ndichite chiyani kuti nditsimikizire kuti chipangizocho chakhazikitsidwa bwino?

CB wailesi - sitepe ndi sitepe ma calibration

Pansipa, m'ndime zingapo, tikuwonetsa njira yapadziko lonse lapansi yosinthira wailesi ya CB.

1. Khazikitsani mlongoti ndi cholandirira mgalimoto. Akhazikitseni momwe aziyendera tsiku ndi tsiku.
2. Lumikizani mita ya SWR.
3. Khazikitsani wailesi ku tchanelo 20 (yogwiritsidwa ntchito poyesa).
4. Sankhani njira ya FWD pa mita.
5. Dinani ndikugwira malo otumizira pa babu lawayilesi la CB.
6. Khazikitsani mita ku malo a SET.
7.  Sinthani njira pa mita kuchoka ku FWD kupita ku REF.
8. Mukugwira batani lotumizira, onani mtengo womwe wawonetsedwa pa chizindikiro (molondola pakati pa 1 ndi 1,5).
9.  Yezerani kuchuluka kwa tchanelo 1 ndi 40 - muyenera kuwerenga bwino kwambiri pa 20.
10. Okonzeka!

Kachitidwe ka wailesi ya CB kumadalira mtundu wa wolandila, kutalika kwa mlongoti, ndi kuwongolera koyenera. Pamaulendo aatali kunja kwa mzinda, sankhani tinyanga zazitali. Kwa mzindawu, iwo okwana masentimita 100. Kumbukirani kuti simukuyenera kugula zipangizo zodula kwambiri, koma kuchepetsa phokoso ndikoyenera. Chifukwa cha izi, chizindikirocho chidzakhala chapamwamba kwambiri.
