VHF mlongoti ndi manja anu: kapangidwe kudzikonda anapanga

VHF mlongoti - chipangizo chimene anafuna kulandira cheza. zosintha izi zitha ntchito ndi chizindikiro yochepa. Chitsanzo wina ndi mzake amasiyana pafupipafupi. Mlongoti kwa FM wailesi ndi manja anu akupita malangizo. Pankhaniyi, n'kofunika kuganizira mtundu wa wolandila. Komanso tisaiwale kuti pali mitundu yosiyanasiyana ya tinyanga, chimene amasiyana kapangidwe ndi magawo.

The chitsanzo wolandila yosavuta

Pali mlongoti kwa FM wolandila ndi manja anu zambiri pa choyikapo choimirira. Pa nthawi yomweyo amakhala bwino ntchito kutalika yaing'ono. Kukonza mizati ntchito kuwotcherera inverter. Makamaka kukolola Posakhalitsa, amene adzasunga thandizo. awiri ake ayenera kukhala osachepera 1.2 cm. amveke wa phwando chizindikiro ntchito amasonyeza. zosintha zambiri pachithandara pa njira pang'ono.

M'munsi mwa mlongoti wa zizichitidwa ndi anakuta ndi. Pa nthawi yomweyo sikelo amaloledwa kulemba pa tepi. Akatswiri amanena kuti zitsulo chubu kuti agwirizane bwino. Pakuti zitsanzo ndi malangizo oipa umagwiritsidwa imaonetsa. Anati mchitidwe yakwera m'mphepete mwa mlongoti lapansi.

chipangizo A ndi chikombole ndi

Mlongoti kwa FM wailesi ndi manja anu amachita nawo mafurikwense osiyana. The zitsanzo pakati pa mtengo osiyana madutsidwe ndi phindu. Pamene kusonkhana unit n'kofunika kukonzekera mlongoti olimba. Akatswiri ntchito chikombole dzenje zolemera yaing'ono. Awiri iye ayenera kukhala osachepera 2.2 cm. Ngati tikambirana chitsanzo amalandira otsika-pafupipafupi, counterweights akhoza anasankhidwa kuchokera zosapanga dzimbiri. Sikuti kukhazikitsa akalowa.

Imaonetsa tinyanga ntchito pa mafurikwense osiyana. Mu msika wa zosintha kawirikawiri pamakhala lapansi. Ali ndi phindu mkulu. Komabe, tisaiwale kuti n'zovuta kubala paokha. Imasiya kutsogolo ungapsereze pa ntchito kuwotcherera inverter. M'mbali mwa mlongoti ayenera mosamala sanded. Poyimitsa ntchito ndi awiri a masentimita 0,3. Kuti tithe kulimbana ndi kumveka zimachitika kusokonezedwa amagwiritsa amasonyeza wapadera ndi madutsidwe mkulu. Chitsanzo ndi oyima yopingasa anapanga ndi mlongoti chimodzi chokha.

Model ndi poyimitsa awiri

Ndi poyimitsa awiri VHF mlongoti ndi manja anu kupita mlongoti lonse. Chitsanzo cha mtundu uwu ali oyenera amalandira osiyanasiyana mndandanda. Childs, ndi mtengo wapatali wa dongosolo kukana, iwo amatha ntchito pa mafurikwense pamwamba 300 MHz. zipangizo zambiri ntchito amasonyeza angapo. Pa msonkhano wa chitsanzo ayenera kuthetsa mlongoti chapakati. Monga ulamuliro, akatswiri ntchito yaing'ono m'mimba mwake chubu ndi malekezero chinzake. Iwo ayenera kukumbukira kuti pali zitsanzo ndi malangizo. M'menemo counterweights akhoza wokwera pa kumathandiza kupeza ngodya zosiyanasiyana. The sitadi kutalika mu mlongoti yosavuta ndi wofanana ndi masentimita 22.

Kuonjezera phindu, machubu zitsulo ntchito. Palinso kusinthidwa khumudwitsidwa. Iwo ntchito pa pafupipafupi 200 MHz. Malangizo a kanthu kwa mlongoti wa zingasiyane. The mmunsi mwa chipangizo ndi akutali chikombole. The imaonetsa ayenera bwino lokhazikika. counterweight mwina wokwera pa malo yopingasa.

Iwo ayenera kukumbukira kuti kugonjetsa phokoso gawo ayenera ntchito amasonyeza elongated. Mlongoti kupirira katundu mkulu. Tinyanga wa mtundu uwu ndi wabwino kwambiri pa polarizations negative. Komabe, mu nkhani iyi m'pofunika kuganizira mtundu wa wolandila ndi malire pafupipafupi.

tinyanga yopingasa

tinyanga Cham'mbali akhoza anasonkhana ndi counterweights wamitundu yosiyanasiyana. Zambiri zosintha anapangidwa pa mizere masts. Palinso kwambiri zipangizo mkulu-pafupipafupi, amene amapangidwa ndi imaonetsa liniya, amene yakwera pansi pa pachithandara. tinyanga Cham'mbali mkulu impedance chiŵerengero. Iwo amatha ntchito pa pafupipafupi 200 MHz.

zitsanzo zambiri zili ndi counterweights awiri. Pankhaniyi mlongoti ntchito ndi masentimita 1.2 awiri. Ena ali oyenera kugwiritsa ntchito ndi amalandira kunyumba. Ali ndi koyefishienti mkulu wa ataima yoweyula. Poyimitsa zambiri pa njira yoyenera. Counterweights basi patsogolo chipangizo.

kusinthidwa ofukula

tinyanga ofukula angathe zikugwira ntchito pa mafurikwense osiyana. Zosintha wa mtundu uwu ndi mkulu amveke china. Ndi choimirira VHF mlongoti ndi wosavuta kwa wailesi ndi manja ake. Choyamba tiyenera kusankha bala yabwino, yokonzekera inverter pasadakhale kuwotcherera. Kuti athetse mavuto ndi kugawanika zoipa akulimbikitsidwa kugwiritsa ntchito zimachitika amasonyeza. Pa nthawi yomweyo miyeso ayenera kukhazikitsa kutalika lalikulu ndi awiri ayenera kukhala osachepera masentimita 0,3. Kuti kumapangitsanso cholinga cha Zosefera ndi ntchito. The desiki kutsogolo akhoza kuikidwa pa makona a madigiri 45. Komabe, m'pofunika Pre-kuwerengera mlongoti mphamvu.

Kuonjezera mtendere wa dongosolo m'munsi zikhoza kupangidwa ndi abutments lapansi. Ndi FM mlongoti kwa wailesi ndi manja awo okha ndi studs yochepa kuti ayenera kuikidwa pa kutalika otsika. Counterweights kuloledwa zibwenzi kapamwamba. Iwo ayenera kusamalira linings lapansi. mwapadera zapatsidwa kwa akufufuza mbali, amene atathana ndi mlongoti wa. Kuonjezera dera kupezeka analimbikitsa chikombole cha masentimita 25 m'litali.

The zida 144 MHz

VHF mlongoti pa 144 MHz ndi manja awo ndi molunjika kapena yokhota kumapeto bar. Mlongoti Pankhaniyi umagwiritsidwa ndi abutments oblique. Nthawi zina, ntchito amasonyeza pulsed. Ndi UHF mlongoti 144 ndi manja ake zoongoka pambali. Kutalika mulingo woyenera kwambiri zogwiriziza ndi wofanana ndi masentimita 15. The zopalira kutsogolo ntchito kuonjezera phindu. Monga ulamuliro, iwo ali wokwera ndi zomangira. VHF mlongoti pa 144 MHz ndi manja anu amachita nawo oyima imodzi kapena ziwiri.

Kusinthidwa pa 145 MHz

VHF mlongoti 145 MHz ndi manja awo anapanga lalifupi mlongoti. The zosintha ambiri amaonedwa kukhala nsanamira zitatu. phindu la zitsanzo za si mkulu. Othamanga ku tinyanga ntchito amasonyeza zimachitika. Kuchitira kutsogolo akhoza anapereka kudzera mwa inverter ndi kuwotcherera. Mu zitsanzo za directivity mkulu. Akatswiri amanena kuti mlongoti amaloledwa kuti mlongoti yokhota kumapeto.

Model ndi mlongoti mkuwa

Pali mlongoti kwa UHF gulu ndi manja awo ndi amasonyeza wa mafurikwense osiyana. Nsanamira akhoza kuikidwa kapena wopanda zomangira. Ena zosintha anapangidwa poyimitsa pambali. Tinyanga chopangidwa ndi mkulu kubalalika koyefishienti. Choyamba wokwera mlongoti. Counterweights akhoza wokwera pa ngodya pang'ono.

The momwe akadakwanitsira awiri struts ndi 1.2 cm. Pankhaniyi mlongoti m'pofunika kugwiritsa ntchito maziko amphamvu. Ngati ife kulankhula za imaonetsa kuti, m'pofunika ntchito zimachitika kapena mtundu waya. Kuti chitsanzo yosavuta ntchito counterweights anayi. Ziyangoyango soldered ntchito kuwotcherera inverter. Komanso, kupanga chipangizo ndi manja anu, wokwera kugawa pansi mlongoti lapansi. Dziwani madyaidya ndikuledzera m'dera chingapezeke mwa struts lateral.

Zipangizo ndi zitsulo mlongoti

Pa mlongoti zitsulo VHF mlongoti wopangidwa ndi manja awo ndi oblique retinaculum. Counterweights anaika, zambiri pa mbali imodzi. Akatswiri ena amalangiza ntchito akapunthwa ndi awiri a masentimita 2.2. Kuti tizikonda cholinga chipangizo umagwiritsidwa zimachitika wonyezimiritsira, amene yakwera patsinde pa mlongoti lapansi. Kulumikiza zitsanzo ntchito waya ku mlongoti lapansi. Komanso Dziwani kuti pali zipangizo ndi lobes mbali. Ali ndi madutsidwe mkulu.

Zipangizo amalandira otsika tilinazo

Wolandila tilinazo kwa otsika VHF mlongoti ndi manja anu ati wosavuta. Sitepe yoyamba kukolola Posakhalitsa, amene zaikidwa mbali kumbali. Counterweights Mankhwalawa amagwiritsidwa ntchito ndi atsogoleri oblique. Machesi udzakhazikitsidwe kwambiri m'munsi. Mu zitsanzo za mtundu ayenera kugwiritsidwa ntchito yikidwa mawaya imaonetsa. Counterweights akhoza kuikidwa pamalo yopingasa. Amveke phindu amaloledwa phiri strut yaitali awiri cm 2.2.

Chitsanzo mkulu tilinazo amalandira

Kwa deta amalandira VHF mlongoti chifukwa 430 MHz manja akuchita zimenezo ndi mlongoti zitsulo. Akatswiri ena mwamphamvu amalangiza ntchito kokha chikombole yokhota kumapeto. Pankhaniyi, counterweights ayenera atathana pa chimango m'munsi. Ochiritsira VHF mlongoti ndi manja anu amachita nawo osiyanasiyana amasonyeza.

Yambani kusintha msonkhano nkokoma kwa yakusankha mlongoti ndi kukwaniritsa mawaya kulumikiza. Komanso, kupanga chipangizo ndi manja anu ayenera kudula mitengo yonyamulira anayi ndi awiri a masentimita 2.2. Chitsanzo mu 200 MHz akhale zitatu mbali poyimitsa. Counterweights akhoza kuikidwa pa makona a madigiri 45. Nsanamira ali wokwera pansi pa mlongoti wa.
