VHF kanyanga nemaoko enyu, asi achizviita patani

VHF kanyanga - zano riri dzaizopiwa pakugamuchira nemwaranzi. okunatsiridza izvi zvinogona chete kushanda pamwe pfupi anonongedzera. Models umwe wakasiyana kakawanda. Kanyanga nokuti karedhiyo nemaoko enyu kuenda pamusoro nemirayiridzo. Muchiitiko chino, zvakakosha kufunga mhando receiver. Uyezve, zvinofanira kucherechedzwa kuti kunongova akasiyana antennas, iyo yakasiyana marongerwo uye parameters.

The muenzaniso nyore mugamuchiri

Kune kanyanga nokuda FM mugamuchiri nemaoko enyu kakawanda pamusoro hunyambiri kumira. Panguva iyoyo zvinoita haaiti nani kushandisa chiduku kureba. Kugadzirisa matanda vaishandisa nomoto inverter. Zvikurukuru kumorwa rechikepe, iyo kuchengeta rutsigiro. dhayamita kwayo kunofanira kuva kanenge 1.2 cm. Nokuti amplification pakati nokugamuchirwa chiratidzo vachishandisa reflectors. okunatsiridza Vakawanda Rack rakareba zvishoma akachinjikana.

Mujinga kanyanga zvinofanira kuitwa nomunhu kuifukidza. Panguva iyoyowo zviyero vanobvumirwa kunyora patepi. Nyanzvi dzinoti kuti simbi chubhu anoenderana zvakanaka. Zvivezwa ane kunaka mirayiridzo rikashandiswa reflector. Akati chaikosha akatasva kumucheto rechikepe.

A Mudziyo ane pani

Kanyanga nokuti karedhiyo nemaoko ako anoitwa pamwe frequencies zvakasiyana. The yokutevedzera pakati yakasiyana conductivity kukosha uye kupfuma. Apo vanoungana kuti chikwata zvakakosha kugadzirira hwakasimba pedanda rechikepe. Nyanzvi angarayira kushandisa mhango pani pamwe zviyereso diki. Dhayamita iye anofanira kuva kanenge 2.2 cm. Kana tikaongorora muenzaniso yakaderera-kakawanda vagamuchiri, kuti counterweights zvinogona kusarudzwa kubva Stainless simbi. Hazvina zvakafanira yokugadza lining.

Reflector antennas anoshandiswa pana frequencies siyana. Pamisika kungogaroita okunatsiridza kuna petals. Vane refu inopfumisa. Zvisinei, zvinofanira kucherechedzwa kuti anonetsa kubereka hwavo.

Nokuti rokurwisa resonance kupomba chipingaidzo anoshandisa hunokosha reflectors dzakakwirira conductivity. Models vane chinjikira kufanira dzinoitwa ne pedanda rechikepe chimwe chete.

Model pamwe Racks maviri

With maviri Racks VHF kanyanga nemaoko enyu kuenda rakafara danda rechikepe. Models kwakadai akakodzera siyana dzakatevedzana vagamuchiri. Kazhinji, kukosha kurwisa mapatani, vanokwanisa kushanda panguva frequencies pamusoro 300 MHz. Vazhinji mano vanoshandisa vakawanda reflectors. Panguva paungano muenzaniso vanofanira kugadzirisa nechepakati rechikepe. Kazhinji, vanachiremba kushandisa diki dhayamita chubhu ine mativi anorodzerwa. Zvinofanira kucherechedzwa kuti pane yokutevedzera pamwe mazano. Pakazoti counterweights anogona kuiswa panguva dzakasiyana pamakona. The mhete kureba iri nyore kanyanga akaenzana 22 cm.

Kuwedzera pfuma, simbi sepombi anoshandiswa. Panewo kurova-rova nadzurudzo. Vanoshandira panguva kakawanda 200 MHz. Direction chiito kubva kanyanga dzingasiyana. Rezasi Chikamu mudziyo ndiyo yoga pani. The reflector inofanira zvakanaka wakaiswa. The counterweight anogona kuiswa munzvimbo chinjikira chinzvimbo.

Zvinofanira kucherechedzwa kuti kuitira kukurira Pasika ruzha vanofanira kushandisa elongated reflectors. Rechikepe kumira dzakakwirira zvinorema. Antennas kwakadai zvakanyanya kunaka polarizations. Zvisinei, muchiitiko ichi zvinokosha kufungawo mhando mugamuchiri kakawanda muganhu.

chinjikira antennas

Horizontal antennas inogona vakaungana counterweights maumbirwo siyana. Simple okunatsiridza dzinoitwa pamitsetse masts. Panewo yakawanda soro-kakawanda mano, izvo anogadzirwa pamwe Linear reflector, riri akatasva pazasi rack. Horizontal antennas vane refu impedance reshiyo. Vanokwanisa kushanda pane imwe kakawanda 200 MHz.

Vazhinji mhando takashongedzerwa vakavirikidza counterweights. Panyaya iyi rechikepe rinoshandiswa 1,2 masendimita ari dhayamita. Vamwe akakodzera kushandiswa ne musha vagamuchiri. Vane refu coefficient kuti amire wave. Racks Kazhinji kuisa panguva yakarurama akachinjikana. Counterweights dzinongova pamberi mudziyo.

mira nadzurudzo

Vertical antennas vanokwanisa kushanda panguva frequencies siyana. Modifications iyi mhando vane refu amplification chinhu. Zviri wehunyambiri VHF kanyanga iri nyore nokuti redhiyo nemaoko ake pachake. Tinofanira kutanga kusarudza bhaa zvakanaka, kugadzirira pachine nomoto inverter. Kugadzirisa matambudziko nezvisingafadzi polarization inokurudzirwa kushandisa kufamba kweropa reflectors. Panguva iyoyowo zviyero vanofanira hwokugadza guru urefu uye dhayamita havafaniri kuva zvishoma pane 0.3 cm. Kugonesa pfungwa yacho filters anechekuita. The dhesiki pamberi anogona chete iiswe panguva necheparutivi rworwendo 45. Zvisinei, zvinokosha kuti kwerubwinyo rwakagara rwuripo ngaaverenge rechikepe simba.

Kuwedzera kutsiga pechingoro mamiriro anogona kuitwa pamwe abutments. Ndicho FM kanyanga nokuti redhiyo nemaoko avo chete Nezvuma pfupi inofanira kuiswa yakaderera yakakwirira. Counterweights akabvumira kuti vabiridzire pamusoro pamatanda. Zvinofanira vatarisire linings. Special pfungwa kurutivi kuongorora, izvo wakaiswa kuti rechikepe. Kuwedzera nzvimbo kupararira yakarumbidza pani 25 masendimita urefu.

The midziyo 144 MHz

VHF kanyanga pa 144 MHz nemaoko avo ari yakarurama kana curved nomuzariro. Mast muchiitiko ichi rinoshandisirwa pamwe oblique abutments. Mune zvimwe zviitiko, vakashandisa pulsed reflectors. Icho UHF kanyanga 144 maoko ake kurutivi dzaro. The Zvakanyanya Kunaka Panguva Yepamuviri kureba pazvitsigiso akaenzana masendimita 15. The pamberi yokuisira zvinoshandiswa kuwedzera fuma. Kazhinji, vari akatasva pamwe anosungira. VHF kanyanga pa 144 MHz nemaoko enyu zvinoitwa nemumwe kana maviri kwamira.

Nadzurudzo pa 145 MHz

VHF kanyanga 145 MHz nemaoko avo akaita pfupi rechikepe. Rakajairika okunatsiridza vanoonekwa kuti mbiru nhatu. inoponesa pakati mienzaniso zvakakwirira zvikuru. Vamhanyi kubva antennas rinoshandiswa kufamba kweropa reflectors. The kubereka pamberi inogona kuisa chete achishandisa nomoto inverter. In yemashoko kumusoro directivity. Nyanzvi vanoti kanyanga anobvumirwa kuti curved pedanda rechikepe.

Model nendarira rechikepe

Kune kanyanga nokuda UHF boka nemaoko avo vane reflectors pamusoro frequencies siyana. Mbiru anogona kuiswa pamwe kana pasina anosungira. Vamwe okunatsiridza dzinoitwa parutivi Racks. Antennas kugadzirwa dzakakwirira vaparadzirwa coefficient. First vakatasva rechikepe. Counterweights anogona kuiswa pane zvishoma akachinjikana.

The optimum dhayamita struts ndiyo 1,2 cm. Panyaya iyi rechikepe zvinokurudzirwa kushandisa simba nechimwe. Kana isu kutaura pamusoro reflector, zvakakodzera kushandisa kupomba yacho waya mhando kana. Kuti muenzaniso nyore inoshandiswa counterweights mana. Pads soldered achishandisa nomoto inverter. Uyezve, kuti mudziyo nemaoko enyu, vakatasva partition pasi rechikepe. Wana bongozozo nzvimbo zvinogona kuitwa pachishandiswa lateral struts.

Namano simbi rechikepe

On a simbi rechikepe VHF kanyanga yakaitwa nemaoko avo pachavo pamwe oblique retinaculum. Counterweights yakaiswa, kazhinji rimwe divi. Dzimwe nyanzvi dzinokurudzira kushandiswa stubs ane dhayamita pakati 2.2 cm. Kugonesa pfungwa mudziyo rinoshandisirwa kupomba reflector, riri akatasva ari mujinga kanyanga. Kubatanidza mienzaniso vaishandisa waya kubva rechikepe. Uyewo kucherechedza kuti pane Namano divi lobes. Vane refu conductivity.

Mano kuti yakaderera utetsa vagamuchiri

Mugamuchiri aikanganiswa nokuti pasi VHF kanyanga nemaoko enyu kuenda nyore. Danho rokutanga kumorwa rechikepe, iyo wanamatira kudivi kumira. Counterweights anowanzoshandiswa pamwe oblique vakapofumara. Match akagadzawo aine hwaro yakasimba. In yemashoko ichi mhando rinofanira kushandiswa that no wired reflector. Counterweights anogona kuiswa munzvimbo chinjikira chinzvimbo. Nokuti amplification of pfuma anobvumirwa kugomo ari vanofamba Pamativi refu dhayamita pakati 2.2 cm.

Models nokuti mukuru utetsa vagamuchiri

Nokuti mashoko vagamuchiri VHF kanyanga nokuda 430 MHz maoko kukaitwa aine simbi pedanda rechikepe. Dzimwe nyanzvi dzinokurudzira zvakasimba kushandiswa chete curved pani. Panyaya iyi, iyo counterweights inofanira wakaiswa nechepasi puranga. Kwakajairika VHF kanyanga nemaoko enyu zvinoitwa nezvirwere akasiyana reflectors.

Tanga kunatsiridza ungano dzematongerwe hwokuchengetedza rechikepe uye tiite waya kubatanidza. Uyezve, kuti mudziyo nemaoko enyu vanofanira kucheka matanda mana ane dhayamita pamusoro 2.2 cm. The muenzaniso muna 200 MHz inofanira kuva divi Racks matatu. Counterweights anogona kuiswa pa necheparutivi rworwendo 45. Mbiru vari hwavapo pakudzika rechikepe.
