Njira YobwezeraMphatso Yaulere
Takulandirani ku Roymall, webusaiti yanu yapadera yogulira mphatso zapadera. Timathamangitsa ndikuyamikira thandizo lanu, ndipo tikufuna kuyamika chifukwa cha kuwonjezera chisangalalo cha mphatso yaulere pa gulilo lililonse lomwe mungapange. Mukagula nafe, simungapeze zinthu zapamwamba zokhazikika zomwe zimakulitsa moyo wanu kokha, koma mudzapezanso mphatso yapadera yaulere ndi odala yanu. Mukonzeka kufufuza msonkhano wathu ndikupeza mphatso zanu zapadera? Yang'anani msonkhano wathu wa zinthu zapadera, ikani odala yanu, ndikuyembekeza mphatso yanu yaulere kuti idze ndi gulilo lanu.Njira Yotumizira
Timagwira ntchito yotumizira zinthu kwa inu mutalandira maodala ndikulimbikitsa kuti zidze bwino. Zambiri zotumizira zidzapezeka mu imelo yotsimikizira.M'magawo ambiri, maoda amakonzedwa mkati mwa masiku 2.Pansi pazochitika zapadera, zidzachepa motere: Mukapanga odala pa Loweruka, Lolemba kapena m'mabwalo a boma, zidzachepa kwa masiku 2.Mwambiri, zimafuna masiku 5-7 ogwira ntchito (Lolemba mpaka Lachisanu) popanda kukhudzidwa ndi kulephera kwa ndege kapena zina zokhudza chilengedwe.Chifukwa ntchito yotumizira yathu ndi padziko lonse lapansi, nthawi yotumizira idzakhala kutengera komwe muli kotero zingafune nthawi zina ndikuyembekezera ngati muli m'matawuni kapena m'maiko akutali.1. Njira Yobwezera & Kusintha
Timagwirizana ndi zinthu zomwe zinagulidwa kuchokera ku roymall.com. Ngati mwagula kuchokera kwa ogawa zathu kapena ogulitsa ena, simungabwezere ife. Zogulitsa zamalonda kapena mphatso zaulere sizilandiridwa kuti zibwezedwe. Kuti mugwiritse ntchito kubweza, chinthu chanu chiyenera kukhala chosagwiritsidwa ntchito ndi kukhala momwe munalandira. Iyeneranso kukhala mu bokosi loyambirira.Mutatenga malangizo obweza kuchokera kwa ife, konzekerani zinthu zanu zobwezedwa ndikubweza bokosi lanu kuchipatala kapena wotumizira ena.Timakonza kubweza kapena kusintha kwa chinthu mkati mwa masiku 3-5 ogwira ntchito mutalandira. Kubweza kudzachitidwa ndikubwezedwa kwanthawi zonse kudzera munjira yanu yoyamba yolipira.Palibe kubweza kapena kusintha zomwe zingalandiridwe ngati chinthucho chinapangidwa mwachisawawa, kuphatikiza kukula kwachisawawa, mtundu wachisawawa, kapena kusindikizidwa mwachisawawa.Mukufuna thandizo lina, chonde titumizireni. service@roymall.com kapena Whatsapp: +8619359849471

Mudzalandira ndalama zonse kapena 100% kirediti ya sitolo mutalandira ndikuyang'ana bokosi lobwezedwa. Kubweza kudzachitidwa ndikubwezedwa kwanthawi zonse kudzera munjira yanu yoyamba yolipira. Chonde dziwani kuti mtengo wotumizira ndi zina zilizonse kapena malipiro sali obwezeredwa. Mtengo wotumizira wowonjezereka sukupezeka kuti ubwezedwe mutabwera bokosi. Inu ndinu omwe muyenera kulipira malipiro awa ndipo sititha kuwaletsa kapena kubweza, ngakhale odala yabwerera kwa ife. Mutalandira ndikutsimikizira chinthu chanu chobwezedwa, timakutumizirani imelo kukudziwitsani kuti talandira chinthu chanu chobwezedwa. Tikudziwitsansinso za chilolezo kapena kukanidwa kwa kubweza kwanu.Ngati muli ndi vuto lalikulu pa njira yobwezera, chonde titumizireni. service@roymall.com kapena Whatsapp: +8619359849471
Description:
This balun is a 49:1 balun for the end-feeding antenna. It only needs to be equipped with a 20-meter-long vibrator (remember to be the standard 20 m) to naturally resonate in the four amateur bands of 7, 14, 21, and 28, and the height-changing resonance The influence of the point is very small, it is very suitable for the HAM with certain hands-on ability (you can make a 20-meter long vibrator yourself), the magnetic ring is a custom-made magnetic ring, and the M-seat is also customized and lengthened (the short M-seat M-head) Screwed to the end or loose), the magnetic ring is fixed by PCB for long-term work and is stable and reliable.
Main parameters:
5-35MHz standing wave less than 1.5 insertion loss less than 1.5DB withstand power 100W PEP (SSB) (Balun is safely passed through the continuous emission test for up to 30 minutes, the parameters are real standards, we will never consider the standard 150W).
Note:
The advantage of the end-feeding balun is that the bandwidth and gain are both NO:~~1 in the natural resonant antenna. The disadvantage is that the loss is greater than the conventional balun. Therefore, the end-feeding balun cannot be used continuously for a long time, and the withstand power is 100WPEP (PEP). Is the peak power) Data communication 100W is double the peak power, remember to use the FM and data communication FT8 mode power halved!
Package Includes:
1 x End-feed Antenna 49 :1 Balun
