Gracias por mostrarnos la construcción de un gamma match a los torpes como yo. En la actualidad en España es muy difícil encontrar hilo eléctrico rigido, ya que la normativa prohíbe su instalación en redes eléctricas de viviendas. ¿sería posible hacer el gamma match con el vivo de un cable de 75 ohms (es decir, con el conductor central y el aislante que lleva incorporado)?
You can use the center conductor of RG8 coaxial cable for this you may also use the non rigid conductor or stranded type as long as you can put it inside the gamma tube.
Muchas gracias, señor. Era solo la información que necesitaba para completar mi antena basada en su video. -------- Thank you very much, sir. That's all i needed to finish my antenna based on your video. 👍😆 👏👏👏👏👏👏👏👏
does ot work ok to mix copper and aluminium? I've used aluminium and aluminium before but not the combo. My inner gamma was 6mm, very important that it's water tight you need a rubber glue or something like colle mastique. (Sickaflex). I'm thinking to play around with more gamma match designs. Loaded coils are another thing i want to better understand.
I re-measured the diameter of the inner conductor using a caliper it is actually Gauge #12 as it is 2mm in diameter solid. So no advantage, the general advantage of using higher gauge wire is the current carrying capacity but you still have to reduce it to fit the SO239 connector and that wire is perfect fit.
Hi sir good morning. Sir bat dipp kayo kuma gawa ng omni directional antenna? Puros yagi nalang po napaoa noud ko. By the way good job sir well done ang galing nyopo gumawa
Sinagot na kita pwede mo gamitin alin man sa dalawa. Yung haba ng dipole i compute mo na lang sa center frequency na gagamitin mo marami naman calculator sa internet.
I mentioned the dimensions in the video if you watched it if you want the graphical representation it's here >>> dw1zws.com/building-the-gamma-match-for-3-elements-yagi/
Gamma Match is for antenna matching, the antenna elements are cut based on the operating frequency in this case 145Mhz. Making of gamma match most of the time is by trial and error you either increase the gamma tube or trim the gamma insert ( the wire inside the tube) until you obtain the best match if you are designing on different frequency, slight adjustment is done using the tuning stub. Use of antenna modelling software is advisable to obtain optimum SWR based on elements length for cutting.
There are different kinds of matching for your purpose depending on what type of driven element you are using (i.e folded dipole), gamma match is just one of them. Choose a suitable matching depending on the design of your yagi. Just search for "yagi impedance matching technique". There are lots of information you can find which can answer your question.
Maraming salamat sir, naka subscribe na po ako sa channel mo. Dami mo na pala videos. isa pang tanong sir, pag nagawa ko na ang DIY yagi antenna with gamma match for signal booster. Kailangan ko pa ba ipa calibrate ang SWR?
1800 po single 3 yagi antenna free shipping na, wala pong kasamang coax di na po kailangan i tune naka tune na, susundin nyo lang yung assembly manual kakabitan nyo lang ng coax na PL259 ang connector at ikakabit nyo sa SMA connector yung UV5R nyo >>> eto po ang video kung gaano kalayo ang abot >>> ruclips.net/video/K6T2saNHjDI/видео.html
Sir sana po ini explain mga details and reason kung bikit danun yung length at mga formula pano nakuha di tulad nyan na ditect measurements na. Building lang naman yan. Sano po may full explaination di puro steps lang.
I research mo na lang po sa google. Dahil baka abutin tayo ng mahabang panahon pag ginawa ko yun. Salamat po sa panonood. saka wala rin pong specific computations ang gamma match mostly trial and error sya.
this video is totally misleading. Remember, the gamma matching is like a capacitor. you should have used the coaxial without the braid. the dielectric must have been included
what is misleading in that? think again many times and you'll find that it is a capacitor just as well. you can put/use many dielectric material in the environment to construct a capacitor like paper, plastic, air end etc to construct a properly functioning capacitor. I suggest you brush up your understanding of capacitor ;) cheers!

Please let me understand it better.
The *_black_* wire has no electrical contact with the aluminum tube inside, right?
👍😷
No contact at all, it is capacitively coupled to the shorting stub on the driven element.
Muchas gracias, señor.

copper and aluminum combination will work perfectly fine :)
how long the gamma match wire used
sir pwdi ka po ba gumawa ng 7elements 2stack UHF po toturial. please please please please 🙏🙏🙏
how are you attaching the gamma match tube to the antenna?
look here ruclips.net/video/TSWR223zObE/видео.html
mabuhay po kau sir.
matanong lang po hindi po ba kailangan swr or nanonva..pag ginaya ko yang sukat .. maraming salamat po
At least may swr meter ka. Kung gusto mo gumawa ng maraming antenna experiments nanovna is recommended. Cost wise mas mura ang nanovna kesa swr meter.
HelloNice education videoHow is leng of gamma match for fm band ,like87.7 mhz?is there any formula ?and for dipole how is leng for fm band,
hi no specific formula for the gamma match however I'm using 10inches gamma tube for the FM broadcast band 87.7mhz, very late reply here :)
Very nice vedeo

Sir pwd b magnetic wire sa gamma match
hindi po kailangan makapal ang insulation ng wire
Is there any advantage of using #12 AWG copper wire instead of the inner part of the RG-8 as the gamma match? Thanks and 73. de 4G1BNC

Pwede ang rg 58 gawin gamma insted of wire #18?
RG8 po pwede RG58 masyado maliit at malambot, yung center lang ng RG8 na may plastic
Hi sir good morning. Sir bat dipp kayo kuma gawa ng omni directional antenna? Puros yagi nalang po napaoa noud ko. By the way good job sir well done ang galing nyopo gumawa
Is this gama match for 27mhz
it's for 2 meter band
Prang ok sa amin yan a.. Pre.?
pang ano freq po yan sir pwede rin po ba sa 435mhz
eto pang UHF >>>> dw1zws.com/building-the-gamma-match-for-5-elements-yagi-uhf/ pang VHF yang nasa video pero same construction technique
Sir pag sa uhf antenna ano po kaya sukat ng gamma match or same lang din sa vhf
Mas maiksi 3.5cm usually ginagamit ko hanggang 6cm
@@EphraimGariguez paano po sa dipole na uhf na may gamma match ano maganda sukat sa gamma sir salamat po ng marami sa reply nyo po
Sinagot na kita pwede mo gamitin alin man sa dalawa. Yung haba ng dipole i compute mo na lang sa center frequency na gagamitin mo marami naman calculator sa internet.
@@EphraimGariguez sir paano yong pag calculate
walang calculation nyan mostly trial and error.
No adjustment rod?
No adjustment rod, but there is an adjustment stub which you can find on my FB page >>> facebook.com/panda.antenna/photos/1464661463873424
Ilan inc po ang wire #18?
eto po ang diagram >>> dw1zws.com/building-the-gamma-match-for-3-elements-yagi/ #12 or #10 po na wire solid mali po ang banggit ko sa video
can i request the dimension of the materials include the gamma match

That is very well constructed but did I miss something? I saw a ruler in your video but I didn't see any measurements.
Measurements is on the video description linked to my website. Cheers!
Paps pwd b magnetic wire ung gamitin pang gamma match at anu ung pinagkaiba
Hindi palit ka ng makapal ang insulation na wire.
Boss ano measurement NG copper ginawa gamma match for uhf? Thanks!
Ayan po ang link ng measurements sa description ng video

Sir how can i measure the length of gamma match. Please help
gamma match is basically trial and error so just build one and use it.
boss mas malaking gauge wire mas malakas po ba? example copper rod nalang. basta kasya sa tube
pano naman lalakas eh nagpalit ka lang ng wire gauge walang ganun
@@EphraimGariguez kala ko sir mas malaking copper sa loob ganun din kalakas. thanks po!!

if ever i make a yagi for 144MHz without gamma match and i impart gamma match, do i need to match the gamma same as 144MHz?

Sir, kailangan po ba ng gamma match if gagawa lang ako ng DIY yagi antenna pra sa signal booster ng phone sa bahay?
depende sa ginamit mong driven element pag split dipole or folded pwede

@@juvanieabejay5663 oo naman hindi mo magagamit ng maayos ang antenna mo for transmission kung hindi mababa ang swr
Sir ilang mm po ba yung 12 awg?
2.05mm dia sabihin mo lang sa hardware makakabili ka nun.
pag bumili ba nyan bos kaylangan pa ituning o nd na kakabit nalang.
1800 po single 3 yagi antenna free shipping na, wala pong kasamang coax di na po kailangan i tune naka tune na, susundin nyo lang yung assembly manual kakabitan nyo lang ng coax na PL259 ang connector at ikakabit nyo sa SMA connector yung UV5R nyo >>> eto po ang video kung gaano kalayo ang abot >>> ruclips.net/video/K6T2saNHjDI/видео.html
pag instal ba nyan sir kaylangan mataas o kahit nd kahit ba saan nakaharap ok lng
kahit 20ft lang unless may malaking obstruction yung lugar mo syempre mas mataas mas ok line of sight kasi ang mode ng propagation ng VHF at UHF
copy sir thanks pm nalang ko pag nakakuha nako ng permit ko. sumali ako sa cabalikat
ok po thanks
Yan po bang gamma macth nayan ay para lang sa 3 element? or pwede rin kahit ilan element.?
pwede rin kahit ibang elements
