The 20 year old beam appears to have suddenly developed an infinite SWR. Replaced the coax below the rotor loop connection, so I am assuming the balun has toasted. Any recommendations for a replaceme
Ron, Nice monobander ! The Force 12 monobanders have a 50 ohm feed. It needs a 1:1 choke balun. I use this balun on my Force 12 40M yagi. https://www.balundesigns.com/model-1115-1-1-balun-1-5-54-mhz-
Ron If its a F12 balun, the long skinny one, it more than likely shorted out internally at the so-239. I have had two go bad. I replaced them with a balun designs 1:1 choke balun. Bob also sells a ni
Ron, As stated B-4 the F-12 orginial small dia. Balun can be problematic over time H2O either at the wire exit or at the SO barrel end . Balun Design are the Balun of choise IMO Wayne , Sent from Mai
That can be a pain to repair. I use Array Solutions W1JR baluns, I am sure that DX Engineering also sells quality ones. You can make one too, see K9YC's website. GL John KK9A The 20 year old beam app
I think K9YC's data on Balun Design common mode chokes would suggest otherwise. Dave AB7E Balun Design are the Balun of choise IMO Wayne _______________________________________________ ____________
Take another look at DX Engineering's baluns. Balun Designs are not the balun of choice. If you want the best in class common mode impedance performance take a look at DXE. Yes, I work there and yes
Tim, Et Al, Golly! Thanks for the update as I am in the process of getting my HDX-555 tower up, after a 5-year hiatus and resurrecting a Force-12 C4-XLD. From 2004 CE until 2015 CE, I had used big Ca
I haven't evaluated current production DXE chokes, but I did measure a Balun Designs 1:1 unit that looking NOTHING like it's data sheet. It was a lousy choke. It is unlikely to overheat, but it's als
Have you seen MyAntennas.com<https://myantennas.com/wp/product-category/balun/11-baluns/> baluns ? Worth to visit. This guy make them best in class, I guess are same level or higher than DXE and Balu
Exactly what is the basis for this statement? My statements are based on 15 years of study of common mode chokes, building and measuring thousands of them. 73, Jim K9YC ______________________________
I don´t think so, he is not even using feed through insulators. 73 Peter This guy make them best in class, I guess are same level or higher than DXE and Balun design. ________________________________
Jim, you know, I am still learning. After 38 years in ham radio, I am a beginner. As I said, it was "a guess" after some comments heard, EHam.net, etc. Talking about guesses... You know Lionel's VE7B
I just looked at the 5KW choke balun on the MyAntennas site. I like the fact that they show the choking impedance. Not so with most of the other providers. I looked for the choking impedance data on
On advice from another of the frequent online gurus (that is, not K9YC), I bought a MyAntennas choke balun to replace the fried line isolator of my Carolina Windom. It's pretty, and its cylindrical
I checked the MyAntennas choke with my VNWA and it measured very close to as specified. Grant KZ1W On 7/21/2020 09:03, N4ZR wrote: On advice from another of the frequent online gurus (that is, not K9

When you mix in all the recent postings by Tom, W8JI, I'm not sure Anyone really knows Anything about Chokes / Baluns. Most of the available data is contradictive. The more I read on the subject the
When you don't understand what you read, everything is going to sound contradictory and confusing. Saying things like "it may or may not be useful" and "I'm not going to be better off than just haph
OTOH, I'm not sure that it's possible to make a choke using recommended (by K9YC) method & parts and end up with a *useless* choke. My recent (2018) Cookbook is the result of measuring several hundre
