Good morning to the group... Pretty much new ham here and I need some advice. I'll be buying a S9 and the radial plate in the near future, my question is...
Owen, You don't have to use steel. Just buy a short piece of aluminum flat stock from the local hardware store. It;s soft and you may just be able to bend it...
In my case, my coax connects to an Unun which has its own so-239, and terminal for radials. Are you planning to use the antenna on multiple bands or only one...
Thanks to you guys, I think I'm getting the picture. I'll need a 1:1 choke balun (same as 1:1 current balun LDG has?). That seems to have two wire inputs and a...
Owen : Just so you know a baling and an unun are two different things. Were you planning on using a tuner? And which S9 were you purcashing. Take advantage of...
How did you guys come out with the tuner boxes? With bands being so bad i'm waiting to see Ron?,who is working up that 43 foot S9. You guys are lucky you have...
Than would be a a Balun ( balanced to unbalanced) and an Unun (unbalanced to unbalanced). The units supplied are rated at 200 wasts and are the same for all...
The LDG site says: " A 1:1 choke balun is recommended to prevent RF from entering your shack via the coax outer shield." So I guess that's what I'll need. I've...
Owen: I can see where the confusion comes in, and you have to "read the fine print" and read their entire recommendation. The answer is sort of an "it ...
Spot on Clyde - funny, I was about to send out a post clarifying the difference - you said it perfectly. Taking Clyde's excellent post just a step further - an...
Thanks everybody !!! Your help and advice has been truly appreciated ... You've got me straightened out. 73, Owen KJ4YAC (and I may be back for more advice as...
Speaking of UNUNs, the 9:1 looks *very* interesting. See: http://www.karinya.net/g3txq/unun/ I think you can buy one for abt $50. Wish someone would try it...
Jess: Yeah, this is a very cool webite. Guy did some amazing research on toroids and various core mixes. I found this site when I was researching UNUNs too....
One thing he does mention in the article is the the power (heat) dissipation ability on the T-200-2 where he says " a loss of 0.4dB means that the safe power...
A few of you smart folks may already know about this. I never heard of it before stumbling on it today. Think 160m. Very interesting toroid transformer...
This resembles a "cobra" antenna which is a short dipole. I did something like this with some of my radials. I cut 16 at 26 feet but my space would not allow...
John, I understand that this system is a "tuned" radial type; i.e., meant to be suspended *above* the actual ground. That is illustrated --See "K2AV FCP...
I don't know that this statement - with ground radials, like you and i have, tuning doesn't seem to be important You just need to "copper plate" the ground,...
I really don't understand, Jim. Are you saying that your system is *not* tuning well? I'd better wait for an answer before opining. 73...~jess, AF5X To:...
Jess: you said this --- with ground radials, like you and i have, tuning doesn't seem to be important. You just need to "copperplate" the ground......... I...
Jim, Long and sad experience teaches me that most arguments are based on two or more interpretations of the same language, so I'm glad to share my own...
OK - understand your "tuning" comment. Notes: - You said, "By some rules of thumb, radials on/under the earth should be as long as the vertical is tall, and...
Maybe you and I read too much, Jim...;-) BTW, the "need to be tuned" statement is something I read in the Butternut instructions. You've probably read it too....
I forgot to add that many have reported data to show that the number and length of radials required by ground- mounted verticals is a direct function of soil...
I have a British acquaintance, a professional radio engineer who knows quite a bit about installing verticals. A while ago, I asked him for advice on coax...
Jess, We've had this exact conversation many times on the LDG Tuners Group. As you have noted, the math does not lie and you are exactly correct. The info to...
Dwayne, I haven't placed the ATU at the ANT yet, because I want to make sure the box doesn't leak...;-) But I intend to. In the meantime, I've collected...
Hi again Jess, Yes, that was probably me on the e-mail. I wear a few hats! I was not referring to technical criteria, but more on how the individual feels...
I know this going to sound like I'm challenging your numbers, Dwayne, but......are you saying that there's a 0.1db difference in loss for an autotuner, in the...
