Using a 1/2 wave electrical line for tuning.

i don't understand analyzers as much as i'd like to . but i get the impression that fine tuning on typical monoband cb antennas with a analyzer vs. a vswr meter doesn't make a difference that's detectable buy most users if the vswr meter was pretty happy to start with . they do look like a fun tool/toy though .

i'm sorry i can't help you ATM and also sorry you're having trouble testing things yourself . i know it sucks when things hurt or don't work the way they used to !!!! maybe there's someone/folks here that can help with testing your ideas and sharing their results ...... when i get my stuff back up i'll be willing to help too .

Thanks BM.

I'm not always convinced, beyond all doubt, that what I do is always right either. I am curious and I try to continue to learn. This is why I like to do more, and when I can provide an idea for another...I like to see if the idea can be duplicated.

As you note, the analyzer only complicates matters, when looking at more than just the SWR and frequency provided. Again, this is why I asked for your assistance.

I don't think any of this will help you get a better tune or a better working antenna. For me, how easy this will be, using an SWR meter and a tuned feed line, has yet to be determined.

A lot will depend on how the match looks on you first check. I think I said earlier, the match might be the same as you had before, since you've already tuned it. In that case there is nothing to do, because it is not worth messing with the tune, just trying to make a point.

But if your match is off enough to really require re-tuning, then maybe this project could be worth a shot. By off, I mean a high SWR, not an SWR showing less than 2.0:1. That is really too close to matter with this idea in mind. So, if you have time and are up to a little record keeping as you test, and re-tune.

Happy Thanksgiving guys.(y)
 
What jazzsinger said.

So, with respect to being able to tune accurately at your chosen center frequency, the e1/2 jumper makes sense to me. I do not think it aids in any way to reduce losses, nor make the antenna work any better except as an aid in getting the match set more accurately when the antenna is originally set up. I have found that long coax runs are friendlier to SWR readings than a hooker on Friday night. Operationally, nothing substitutes a good feed line quality as close to the shack as is possible. Someone correct me if possible.

Thanks for the information, I tend to agree.

Happy Thanksgiving
