Felicidades por un vídeo sencillo y clarificador.

Great vidéo , greetings from Belgium 73 👍

TNX, 73..

EXCELLENT DEMO , THANKS NS9T.

Excelente video, gracias por compartirlo, con los amigos radioaficinado

[@yv5emghamradio249]

Gracias Beltrán. 73.

[@pleasetryme]

if i study this correctly count the red wires has 11 turns and the other has 10

[@dannystephenson4957]

Could I use 1.5mm copper enameled wire?

[@juliocesarpereira4325]

Thanks a lot. 73!

Is this Balun used only for dipoles? Is one needed for a beam antenna say something like a single band 3 element yagi with a gamma match, matched to the center freq of the band (10 Meters)? The yagi's driven element is basically a rotatable dipole.

[@yv5emghamradio249]

Yes!.. it works with any Antenna, remember, you need for a perfect match, 2 elements that connects your antenna with your radio.. a Impedance coupler.. and a Common Mode Current supressor.. in case, your antenna it's a symmetrical antenna , like a Dipole, you need only one 1:1 Balun like this, .. but if the antenna , needs, another impedance relation, like 4:1, 9:1, etc... , You need 2 Baluns.. The Impedance Match, and the Common mode Current noise supressor..

hi is all 1:1 Current balun 12turns each side？ or it depend on the toroid size ，Thanks 73

[@ernestotekhaus3818]

Excelente amigo. Saludos al Gato :)

[@yv5emghamradio249]

Retornados y Gracias!.

[@imken2392]

Is the 32" wire length important other than having enough to finish the wraps? Also is the length of the wires at each finished end important. I made 2 after I watched this. They both give different readings on the10 meter dipole. I used the same torroid and the same wires as in the video. Tested with my RigExpert AA-600 and the Icom 756 pro III.

[@yv5emghamradio249]

I Ken, ..the initial length of the wires for making the Balun, are not important, only for avoid the mess with long wires... But., try to keep the finished ends, wrapped and no longer of 2 inches.. Try to keep the wire, equally spaced on each turn and very tight to the Core.. It's almost impossible to make, to Baluns exactly equal., 73

[@brandonlaragirl]

What do you think about that analyzer you mentioned. I'm looking into getting one. Has it turned out to be what you expected? Thanks in advance, 73s

[@HughJarse1968]

Does it have to be exactly 12 turns? My wire must be a bit too thick, I can only get 10 turns on the ferrite core - is this enough? Many thanks for any comments & help :)

[@theroguetomato5362]

Same here. I wish someone with know-how would answer this. In the meantime, I'm going to try different wire to get 12 full turns.

[@arconeagain]

I take it 16AWG is okay?

[@balasubramanyancp882]

What type of torroid used? Type #?

[@imken2392]

By stacking cores to increase the power handling capability, Say 2 cores for 500 watts or more, would the wire size need to be increased as well?

[@N1SEP-]

no, stay with 18AWG, but maybe use PTFE wire, much better heat rated

[@luisradaelli5691]

muy bueno colega, se puede hacer uno con núcleo al aire y tubo pvc?

[@yv5emghamradio249]

No de este tipo o configuración, los Choke Balun de "Aire" con tubos PVC, son totalmente diferentes, poseen un rango de atenuación de la Corriente de modo común, mucho más "leve". y no son tan eficientes, como uno con núcleo de Ferrita.

[@kanaiyalalkotak2638]

After completion of wire wrapped what Next ???

[@user-iu7eu3vr1o]

Power?

[@pa9x]

Nice demonstration! For what maximum power do you rate this balun?

[@yv5emghamradio249]

With this Toroid, easy 300 Watts nominal, and 500w peak, (only few seconds).

[@pa9x]

@@yv5emghamradio249 ok, tnx!

[@PY4SR]

I believe the designer of this balun, Wolfgang Wippermann DG0SA, rated it to 800w. FT240-43 as core. The isolation must be PTFE and the wire 18AWG, silver plated. 73

[@michaeldavidson9939]

Couldn't get through the video because of the obnoxious background noise (soundtrack).

[@matthewlee2686]

​@@michaeldavidson9939stop bitchin they make a volume and mute button for a reason.

[@kissingbanditt]

Which side goes to coax? Or it doesnt matter?

[@yv5emghamradio249]

Each side works the same In or Out, and you can put the centre of Coaxial cable in the whatever color you want, and the shield on the other. In the same side off course. 73.

[@user-uw7os9zr5b]

THAT'S FOR SURE 1:1?

[@EA3FNI]

¿QUE RANGO DE FRECUENCIAS CUBRE? DE 1.3 A 10 MHZ

[@EugenioGuarente]

Si.. de 160 a 10 mts.. , 300 watt continuos.. con ese Toroide

[@ea3fa]

@@EugenioGuarente Se podría cubrir de 1,8 a 50Mhz con la misma configuración?? En caso que NO, qué cambios serían necesarios?? Gracias !!

[@TheAdrenaline85]

The videos I’ve been seeing on YT don’t help a novice beginner. I’d hoped they would.

[@alexalonso2093]

ty for showing us how to step by step too many hams go to fast .and we need step by step ty plz show us more how to connect to anntennas 7 3

[@yv5emghamradio249]

Sure, In the next video, I will show how to put on a plastic case, with the female so239 connector, and the two antenna terminals, and on a 3rd video, the implementation on the complete Dipole. 73..

[@Joe_KS1I]

I'm curious, why FT240-43 and not -31?

[@gravestonemyth]

Same here. I know the 31 mix is preferred for coax-type current baluns.

[@W-733_KWX]

Same on my side, 31 mix is better for 1:1 to remove RFI (common mode). For efhw mix 43 is prefered.
