- This is my first attempt to build a Shortwave Loop Antenna. I already have some improvements on mind but they will be on another video!
(Este es mi primer intento de construir una Antena de Loop para Onda Corta, desde ya tengo algunas mejoras en mi cabeza, pero estas estarán en otro video!)
Very good choice of music. This was my first record as a kid in the early 1950's, when I build a Hi-Fi. No stereo in those days.
Thanks Jim. Mozart is my favourite!
Good video. Great music. But only 340 likes, I dont understand. What more do they want ? This is the best video that I have seen on how to make SW loop antenana. Keep up the good work. Dont give up.
Thank you Ronald for the kind words!
VIVAN LAS EMISORAS DE ONDA CORTA INTERNACIONAL!...EMISORAS Q SI LLEGAN AL MUNDO!...A MEJORAR LA ONDA CORTA, NO HAY NADA MEJOR Q LA ONDA CORTA PORQ ASI ESTAMOS BIEN INFORMADOS ...
Magnetic loops like this work very well on transmit too, for amateur radio. With your tuning capacitor you could operate with a few watts but at higher powers you'd need a wide spaced variable capacitor as it would arc over with the very high voltages at the ends of the loop at resonance. mag loops really do work well and can make a big difference if you live in an area with lots of noise on the bands. Very nice build! 73
+roogalater Thanks a lot for the kind and useful comments! Yes, your're right but, being just a beginner in amateur radio, this antenna is intended for DX purposes only...Thanks again and 73's!!!
Nice project. I live in an apartment and I picked up the tubing to build a loop this week.Receive first then I will build one to transmit with
Very instructive! That is the ID of Radio Romania. Beautiful job 73!
Gran vídeo como siempre y gran sintonía radio Rumanía internacional
Great!!! You are inspiring me to built my own short-wave antenna.
Nice work. RRI has the best signal on SW +40 DB on my G5RV. Look forward to your next video.
Nice job! This is something anyone can build at low cost!!!
Thanks a lot Shortwave Listener!
Very well done, this antenna looks really great and it performes very good. Thank you for making and uploading this very interesting video!
Thank you Dieter for your kind words.
I love shortwave thanks for the video, good work
Well done! Thank you for sharing.
good job..and the neatest work bench I have ever seen..wonder if you were going to stain the wood at some point..but still a great piece of art..
Thanks for the nice comment. I'm a kind of "tool-holic" hehe! About stain the bench...I don't think so, since that help me to remind that is a "Work-bench" and not just a nice "bench" to care of...so being as it is right now, a couple of scratches here and there, make it look better and "well used" than with a bright polished varnish coat!
Wow! this looks amazing! thanks for making this tutorial, I´ve been looking for this quite a long now. I´ll try it out, thanks again! and I´m subscribing btw :)
Nice job. You might want to consider attaching a 6:1 vernier drive to that capacitor. It would give you a little more precision in the tuning.
Nice Project. Cheers!
I agree it is a good looking antenna, thanks for sharing, Love the music also.
I am always building all sorts of contraptions for my receivers, and that tune that comes in at 6:46 I have heard here in England can you tell me what it is from...
Anyway like I was saying my antenna's are a hit or miss as I have hundreds of feet of various size copper wire donated to me for some PC system work I did for my local cancer hospice " I found it in trash dumper "
I have very little knowledge on antennas and find it very confusing.
Thanks good upload I may try one of theses one day.
Video very nicely done my friend. Anyone should be able to build this loop using the video. Great Job, and I enjoyed watching. 73
That's pretty cool. I have to build one.
Very nice work and video!
Thanks a lot 1963Dx !
It's not a video it's a slide show.
nice work. i have 2 questions though. is hollow copper the tube necessary or just wore will do ? and where you connect the 2 ends of the rf cable in radio ?
Try to connect this antenna to: 1. the crystal radio. 2. simple trf radio with 1 fet (2sk241, 2sk544, mpf102, bf998, etc)
Nice Video !
excelente Gracias por compartir
Nice article. How could we by using the same method make a AM/MV antenna?
It would be nice, if you spoke out about your video project. Seems many have their tongues locked up these days for some unknown reason.
Thanks for the Mozart!
Hola Juan! Tendrás los planos para armarla? Ojalá me quedara un 10% de lo profesional que se ve la tuya!! Abrazo
Nicolas Solop Hola Nicolas. Gracias por tu amable comentario! la verdad no existen planos para la construcción de la antena puesto que la única medida "crítica" es el perímetro del loop, que en mi caso es 10 pies (3 mts). Espero que mi respuesta sea de ayuda para tu proyecto y por favor déjame saber si te puedo ayudar en algo más. Saludos Y felices radio escuchas!
Juan David Barrada entiendo Juan!!! Solo dow consultas más, la medida del loop, los 10 pies, es el diámetro o el perímetro?la otra, Para que frecuencia sería esa medida?
Hola, si, como lo mencioné en mi primera respuesta, es 10 pies de perímetro...la frecuencia de resonancia dependerá de los valores máximos y mínimos de tu capacitor (una vez conozcas las características de tu capacitor, es fácil encontrar algunas calculadoras para este tipo de antenas online) Suerte con tu proyecto!
Can you make this antenna with 1/2 meter loop?
Great thanks for the video. Summer project. 73's
Good luck! 73's!
This antenna is better than long wire antenna or RGP3 antenna? Isso think the long wire antenna with balun is the best antenna in shortwave (SWL) or not?!
João Damasceno Hi. I'm not sure if this antenna is better than the "Long Wire Antenna" with a Balun, I haven't done a comparison between those two but I can tell you that this one works great! (By the way, I'm going to do the comparison exercise soon....you got me thinking about it!)
+Juan David Barrada what "range" this antenna have?
Me podris decir por favor, como hicistes, el adaptador para la Sony ICF... Lo video es perfecto, yo que no puedo copiarlo.Si posbile decime algo mas. Myuchas gracias
I've just found this info on the web and I've been doing some experiments about of it..."trial and error"...but I think that finally I found the right coupling for my radio.
I'm attaching the link to the page where you can find some info on this matters and some also some drawings (unfortunatelly is "just a bit" of info):
www.mds975.co.uk/Content/dxshtwave.html
Sorry I couldn't help more. Please let me know if this way works for you.
Thanks a lot. I guess, I ve done well, but this make me clear, because I have to match better..... By the way:(It is usually much more effective to indirectly couple the aerial to the radio: Wind the last few centimeters of aerial wire into about 6 to 20 turns around a paper tube and slide this over the telescopic aerial and adjust its position along the rod until the best signal coupling is found. Sometimes even better results are obtained by connecting the free end of the wire to earth.)
SI COMPREENDI BIEN: hay dos posibilidades : poner positivo(antenaI y tierra.. y la mejor es hacer la pequeña bobina, para poner al redor de la antena de la radio,sin conectar la parte que seria Tierra?? Es asi?
DE TODAS MANERAS HE PROBADO de las dos formas. Lo que debo rever es la cantidad de vueltas de la pequena bobina. Gracias por la atencion y respuesta.
felicitaciones aunque tarde
+horacio calle Nunca es tarde! Muchas gracias!
muito legal,73 colega
Thanks a lot!!! 73's!!!
what are the tuning knob specs big loop antenna side so I could complete my build
Variable Capacitor 365 pF
www.amazon.com/Capacitor-Variable-Single-365-Rotation/dp/B00EQI9K9O
Nice
...I'm not sure...maybe 20 bucks?...yes...around that!
Why 10 feet?
Cost?
7:40 radio romania
Us aliens have one of these
On the planet Zorb.
Excellent video tutorial! Cool, I'm planning on building one soon for my Tecsun PL-310ET. I'm looking at your plans and also the instructions at www.kr1st.com/swlloop.htm to figure things out. What range variable capacitor should we use? Is the coupling loop electrically isolated from the main loop? Does it have to be at the side or can it be central of the main loop? Does it have to be 1/5th the size? Thanks.
That music is yuky
This a is a wrong way to build a short wave antena, you will never have a good signal, the short wave radios works on band wave lenghts of 60, 49 , 31, 25,19,16, 13 and 11 meters and in order to get a good reception the wire lenght must be designed at least to pick up a 1/2 wave lenght of the electromagnetic signal short wave; I have a ZENITH transoceanic radio fully restored wich has a very good reception stations from Cuba, Spain, Checoslovaquia, China, Rumania, USA, Francia, Brazil; I must tell that today there are few countries transmiting in short wave in comparation with the 40's, 50's, 60', 70's.
You are talking about "wire lenght" which corresponds to a wire antenna as its name indicates, this is an "active -tunable- loop antenna"...and please believe me when I tell you that I have awesome results! (As you can see and hear in the video!😉) Thank you for commenting my video. 73's!
@@juandavidbarrada Thanks for your answer, my comment is just to explain how an electromagnetic wave is handled and received on a transmission line, there are a lot of antena experiments, but for me doesn't work.
no specs? how helpfull is that thumbs down
Please tell to person who told you to write this comment (whom I guess doesn't know how to read ... since all the technical specifications are in the video...BY WRITING!) that the only things that don't have an specifications (like the stand) can be solved with nothing else that a bit of imagination! in the future,PLEASE BE SURE YOU COMMENT and your THUMBS DOWN obeys to reality and not to your imagination!
