You are very welcome! 🙂

I am glad that this video is helping to make sense of things. But I am not familiar with an AE license. Please do not use acronyms, not everyone will necessarily know what you are talking about. 🙂

Thank you so much! I've played with electronics since I was in grade school. Ham radio and electronics all through Jr High and High school. I was in the USAF with an electronics related specialty. Getting out of the USAF, I became a biomedical technician working for a hospital. Eventually I got my electrical engineering degree and have worked in the heavy military electronics, medical and petrochemical fields. The later two as a product design engineer. Why EIE? Check out my introductory video: kzbin.info/www/bejne/mJS3hoOAoZ6Ehck 🙂

You are very welcome! 🙂

I can see your point. From my point of view, the antenna stops at its feedpoint. The question is ... what do we consider to be the feedpoint. In the end, in this sort of situation, what works ... works. If you watch the video on the folded dipole for 2 m where I take the 4:1 BALUN created here and use it with this antenna, it works. 🙂

You are very welcome! 🙂

Thank you! 🙂

Well thank you very much! I had to say as I read your comment, "That is EXACTLY what I try to accomplish in my videos!" 73 and God bless you as well! 😁

This sounds like a nice experiment to try! 🙂

That would be Electrical Engineering with an emphasis in R.F. Engineering. 🙂

@eie_for_you Thats great Thank you

Thank you! 🙂

Thank you so much ... and you are very welcome! 🙂

Thank you!

Thanks! 🙂

LOL! Thanks! 🙂

Now THAT is a good point! 🙂

@eie_for_you Before I saw this video, I had a bit of a problem of having cheapo snap ons and proper ones on the shelf. I gotta test this out. Oh, and same for toroids! Good luck trying to remember which ones were #43, #31 and #52 mixes! A bit of paint on the side wouldn't hurt on manufacturing side. Though, dumb user like me forgot to mark down what they were when I got them

@@OH8EFI A lot of toroids are, indeed, color coded ... if you can remember what the codes mean. At least you can group them by color! 😁 If I remember right, Amidon tells you what their color codes mean on their data sheets. 🙂

Having no personal experience with End Fed Half Wave Antennas, I can only repeat what I've been told by those who have ... 9:1. 🙂

Can you measure a piece of wire 1m long (EFHW for a 2M band)?

@@galileo_rs First of all, I'm not sure if you are trying to measure its end-to-end response or its its swr or its impedance. Could you please be more clear in what you are trying to accomplish? Second, I do not do acronyms. I can only guess at a host of possible meanings which does not help in clear communication. 🙂

@@eie_for_you It wasn't a question, it was a response to the previous question.

@ Aaaaaaaahhhh! I missed that! When I click on the comment, it doesn't bring up what came before and it gives no indication to me that I have some context to consider. Sorry for the misunderstanding! The VNA needs both the signal and the return. A simple wire hanging out there without some sort of return path won't work. Your end fed half wave antenna also needs a "counterpoise" as I understand it. This functions as the "return path" for the feedline. So, if you have your antenna and its counterpoise connected to the nanoVNA, then it will, indeed, tell you what it sees. I hope this helps. Again, sorry for the misunderstanding. 🙂

WOW! That is great advice! 🙂

Thank you! It is to reduce the signal coupling for the isolation tests. Conductors at 90 degrees to each other have a lot harder time inducing signals in each other.🙂

@@eie_for_you Thanks for the clarification. Seems like an important detail.

@@jmcexx You are welcome! 🙂

Gotta love those AI translations! LOL 🙂

Thank you so much! I'm glad this video was helpful to you! You are very welcome. 🙂

Thank you so much! Honestly, I'm not sure what the numbers actually mean. Sorry. 🙂

Thank you so much! It was most certainly a fun video to produce. Thank you for the blessing for me and my family! 🙂

@@eie_for_you Excellent! And you're very welcome!

@ 🙂

Thank you! I don't know if you noticed that I compared a similar size cheap Amazon tubular ferrite to a very generic box style to a genuine Fair-Rite box style. You are right, though, if you do not need a lot of attenuation, then the cheapies will work just fine. It is all about the application. Figure out what you need and select the ferrite that will do it for you. 🙂

​@eie_for_you thank you again for the excellent video!

@@daveN2MXX You are *very* welcome! 🙂

Thank you ... and you're welcome! 🙂

Well ... the cost is very, very supplier specific. So, quoting costs wouldn't be too helpful here. Furthermore, there are a lot more factors involved than just cost ... like space considerations and dissipation factors and more. This is why you have to do your homework. 🙂

Thank you! And you are right ... that is why it is so important to go to a known good supplier like Fair-Rite. 🙂

When many people look at all of these specifications, their eyes glaze over, not sure what it all means. This is why, in the end, if we are not sure what we are looking at when we look at the catalog, their is always customer support. 🙂

Thanks! 🙂

Yep, the wire isn't insulated as I stated in the video. I'm glad you found a good source of ferrites. 🙂

Yeah ... they aren't always a cheap as we would like, but if we want to get the job done, we have to pay the price, eh? I'm glad that you found the video helpful. 🙂

Thanks! That is very encouraging. 🙂

Thank you ... and you are very welcome! 🙂

True that! But we often have no choice but to accept the shortcomings of other people's designs. Thus, we are stuck with clip on ferrites. 🙂

There ye go! Each additional turn adds some benefit. But, it is the law of diminishing returns, as I show in the video. Yes, each additional turn adds more benefit, but less than the previously added turn. 🙂

When you say "turns" you mean winding the wire through the hole and around the outside of the body of the ferrite, as in repeating loops through the ferrite?

@@echadmiyodea Each pass through the ferrite is a "turn." The key is that the wire passes *through* the ferrite. Having it beside the ferrite, on the outside, doesn't count. 🙂

Up to a point. Inter-turn capacitance (mutual inductance in the case of shielded cable) will affect the higher frequency performance. But if you cascade one single turn and one multi-turn, perhaps you get the best of both worlds. I don't have the kit to measure that, unfortunately.

@@lumpyfishgravy Well ... sounds like the voice of a truly inquisitive experimenter to me! 🙂

Thanks! 🙂

Thank you! 🙂

Cool! 🙂

I LOVE the success stories! 🙂 I wish I could put a ferrite on the entire city of Dubuque! We have an S7 to S9 noise level here and it is guys to the south of the city and guys to the north all have the same issue. I've turned off my own main breaker and ran my radio off battery ... no difference. 😞

@@eie_for_you I know of what you speak! Keep after it, you will find what it is eventually! I have had s7-s9 noise here in my town, which is power line induced. It changes with weather, and seems to follow a HV feeder that passes my house about 300 ft to the east of my house . 4 or 5 blocks on either side of the line, the noise tapers off. It also reduced a lot last spring, but it seems to be coming back. Interesting thing, I had the power line drop coming to the house from the alley put underground (at my own expense) to give me more room for antenna construction, and while that was in process I noticed my neighbor had his power drop from the pole to the house and it was rubbing on a large tree limb. I noticed also that someone (doubt it was the utilities people) had wrapped what looked like part of a rubber door mat around where it contacted the tree and secured it with zip ties. So, I will be looking at this a little closer when the weather warms up this spring! I suspect that there was or is still leakage to the tree when the tree is moving in the wind, and it makes its way back to the feeder by the transformer in the alley passing the noise to the primary side. It then radiates out from that line which runs to a much larger substation 5-6 blocks north of me. 73 and good hunting!

@@arnoldgrubbs2005 I hope to do a mobile search with my RF Explorer and a portable antenna....sometime! 🙂

@Electrotech1980 can you share a link for the Mouser beads that you selected and successfully tested, please?

@ Yes, please share your discoveries. 🙂

🙂

Thank you so much for the encouragement! I am so glad that this video was a blessing to you. 🙂

I did, indeed, make a note to pick the right material for the job. Good point about the split core. I would assume that the split core is a compromise for the convenience of being a clip on. I'm not sure how much that affects overall performance. 🙂

I think material is the same thing as "mix" or..?

@@OH8EFI As I understand it ... yes. 🙂

You need a 2 port measuring device to do this measurement. The Stick 500 is a single port device; it measures things like SWR, return loss, impedance, and the like. It cannot measure things like filter frequency response. This ferrite business is, in essence, a frequency response-type test. 🙂

Thank you for the great advise! I cannot agree with you more. 🙂

Thank you! I'm glad that you found the video helpful. I'm not sure I know what you mean by promoting my "fantasy figure." 🙂

This is a dumb comment. The presenter did a great job!

@@hankhamner3671 🙂

I think you commented on the wrong video or something.
