Balun One Nine v2 - Small Low-Cost 9:1 (1:9) Balun with Input Protection & Enclosure for HF & Shortwave. Great for Software Defined Radio (RTL-SDR & SDRPlay), Ham It Up, and Other Capable Radios

I have one connected to 135' of wire and a second as a spare. These work great for HF listening with a long wire.

The device is packaged well and will be a good addition to my receiving antenna collection.

I used this balun as an unun for my random length (I chose 119 feet based on my research) long wire antenna and my Eton Elite 750 shortwave receiver. I compared it to the telescoping unit antenna on several bands and the long wire antenna through the Balun One Nine V2 had superior reception every time. It also was better on FM reception. I was cautioned that this is for receiving only and the Balun One Nine V2 CANNOT be used for transmitting, if you're a HAM looking at it for that purpose. I'm very satisfied and glad that I didn't choose one of the many balun kits available online. I just attached it to my antenna wire, ground wire, and coax on the other side and I was on my way. I used a LeMotech ABS Plastic Dustproof Waterproof IP65 Junction Box (5.9" x 5.9" x 2.8"), available on Amazon, to put the balun into for weatherproofing. Search the questions on this product for a good description on which lug is ground. Again, it works really well.

well made and works perfectly, I love it.

as advertised

Worth the money, very durable, I've been using this for over two years. Easy to use, pluc and play. I use this on my RWEF antenna for SWL.

This balun works. It cleared up medium wave reception enough to receive stations. I would have pulled the balun out of the antenna system to show the mountain of noise there is which was blocking any reception except the strongest radio station but it is mounted to high up and I don't have a ladder to reach it. In the video you see SDRuno software which is interfaced with the SDR Play RSP1a. You can see some noise and hear some noise. That is with the balun one nine v2 with a ground wire connected to it. I don't see much of an improvement on shortwave reception up to 30MHz. I wouldn't expect a miracle. It is just a balun. It matches an unbalanced antenna to a balanced receiver. I do recommend the Balun One Nine V2 with the case. It is a nice little product and is somewhat effective.

I installed this on a random wire end fed (80ft) antenna I put up for my shortwave receiver. It really helps with pulling a nice clear signal on pretty much every band. My only wish is that the case was weatherproof but I just put it in a little plastic box and sealed the wire holes.

j'avais acheté le modèle moins cher sans boîtier et ca fonctionnait.. avec celui-ci j'ai pu comparer les deux versions et j'ai remarqué un signal/bruit meilleur de 5 @ 7db avec la même antenne.. noter que le boîtier peinturé n'a pas de contact avec le connecteur "sma" et donc, j'ai sablé le trou du "sma" de sorte que le boîtier soit mise à la masse via le connecteur (la différence est négligeable, environ 2db) mais ça me semblait important.. naturellement, j'aurais dû acheter celui-ci au tout début.. il n'est pas étanche mais le circuit interne amélioré est plus performant (même sans le boîtier)..

Excelente para recepción (no transmita con el) supera a varias antenas que probé en mi radio de onda corta, compre una extensión electrica de 10 metros, corte los extremos, dividí los cables y se los coloqué a este Balun, lo coloqué en V con mástil a 5 metros. Soy de Ciudad grande, no se oía gran cosa más que en la noche, con este artefacto a todas horas se escucha radio de varias partes del mundo. Muy bien.

Perfect

Working great. Important to set up counterpoise too. Works great on all HF amateur bands. In the image 80m band using AirSpy SDR
