More video Good job

Wonderful idea. Though I have used WebSDRs to hear radio amateurs earlier, never thought that it could be used to find the front/back ratio of your antenna! 73 de Jon, VU2JO

Ok I think you are the right person for my question to you, can I get some specification for the, 2,3,4,5 element yagi flat side antenna, i wanted it for the 11meter cb band, I am a cb radio operator who always make my own antenna, please an thanks bro, if you are going to help me, i will send you my phone number for WhatsApp, watching from Jamaica west Indies !!

It's been two months since your last video. Hopefully, you are preparing something new. Keep up the good work and let us know. 73!

Nice setup!

will my mfj-259 analyzer show me the correct R value???? it a cheap device and I had to repair it but it works and I dont have much money

Awesome information! Enjoying your videos immensely! Thank you!

Excellent explanation!

Steve, every week I come to your vedeo channel hoping to find a new video. Are you working on a new device or planning something new? Thanks for your time, efforts, and knowledge you share with us.

To make it 50 Ohm, I only need to change the resistors, 150 Ohm to 100 Ohm and 75 Ohm to 50 Ohm? Also, can this be used in the 470 Mhz range?

Hi, great video. Does the Siglent generator output the trigger signal on the "SYNC OUT" connector?

Thanks for making such a detailed video. Could you make a part two and show how you feed the shunt wires? For instance, did you replace the variable capacitor with a fixed capacitor? Was the measured value of the variable capacitor the same as what you ended up using for the fixed capacitance? How do the two shunt wires connect to that capacitor? How is the coax connected and the whole thing protected from the weather? It would be really interesting to see how the relays work at the bottom of the tower, too. That's an amazing remote antenna setup!

Is there any chance I can still find the 2N5109? Is the 2N3866 a direct replacement? Both are listed as obsolete at Mouser and Digikey

Steve, do you remember which wire gauge you used on the binocular transformer, please? I do appreciate your comments. 73!

Excellent, thank you! Too bad it took so long for UA-cam algorithm to figure out I was on the lookout for it.

low temp solder is only good for desoldering during rework and not for permanent soldering

Thanks I learned some new tricks I did not know! 73 Kari SM0HRP

The most useful video on the subject. Thanks a lot!

Wow. Breathtaking what all you have done.

I'm using version 9 here. Great prog. Are you still using it ?

Best ham radio videos in the game. Keep up the great work!

don't forget that using different receive locations will give you different result ,as the vertical radiation patern is different for the different vertical angles. and this method does not compensate for condx and possible signal reflections on the tx or rx location(s).

Excellent content as always, Steve!!! Do you know of an online polar plotter, or perhaps a way to do it in Excel? Thank you for posting! 73 VE3GKT

Nicely done! Thank you for sharing this useful information Steve! de VE6WGM

And don't forget to ID.

Oh look! Dirt! Of course nothing on the actual antenna. Typical of the HAM Hobby. Nothing to show lots of talking though.

How important is it to be able to control the impedance of the board/traces when doing this? Are you using a calculator of some sort to keep it all ~75Ω or does it even matter at that small length in relation to the wavelength? The transformer and op amp input might not really even care, but I always wonder about that...I have a number of projects I have had made via JLC as well, but have never done anything with any kind of accuracy/impedance control required. The only Design Rules I use are just wider traces on power rails and ground-flood where it makes sense.

Nice to see the VE7AV SDR make it to your video. I'll share the link with Frank. He'll be thrilled. I've often used this method for testing my antennas performance. I'm on about a 1/3 acre lot and have been able to put up antennas for all HF bands with 2 on 80 (1λ loop, 1 inverted V) 4 on 40 (1/4λ vertical, vertical delta loop, inverted V, and a horizontal loop) and so on. This same method is how I was able to "see" the effects of ground losses as I saw the improvement made when I went from 4 full length radials to a 20-something on my 160M inverted L. Thanks again for all the time you sink into these videos. Bob, VE7WNK

What was the step sweep frequency?

I am really loving your channel. It would not be the week between xmas and the new year without bingeing on beverages (the traveling wave kind). I recall seeing a video of yours, at least a year ago, about your shunt-fed tower, and now I am back and made sure to subscribe. I also make my own boards. You are inspiring me to share my projects :D

Impressed. Was wondering if we could sponsor your antenna series in the near future? Hope could reach out to you.(PCBWay luz)

How about using a drone to suspend a very tall vertical monopole for 160m, 630m, and of course 2200m ? Might need a bigger drone to hold-up 550m of wire.

Hi Steve,

This is a gem. I'm glad that I'm able to process like 80% of what's all going on here. My jaw really dropped when you showed off how you just click around to remotely select what compass heading you want, like it's no big deal. Excellent work

Very impressive rx system, professional grade

Nice phase array antenna

Will this same process work to sweep the IF cans at 455khz on a radio? If so I've been searching for years for a way to do this. Any suggestions would be greatly appreciated. I have a siglent SDG1032x and a Rigol DSO very similar to the scope in this video.

any thoughts on a 130ftx 30ft garden and what options for rx antenna on lower HF bands?

Excellent work neighbour! - VE7WNK

The atomic structure of the wires become more compact and therefore a more dense wire is harder to vibrate with the radio waves. Not sure I’m saying this correctly but I think you get the general idea.

I almost made it to nine minutes before my head exploded.

Hey Steve . Greatly appreciate such a very illusive and complete technical explanation . Tnx . Good luck in the coming winter season. 73 de ON4DS/OP5T

Steve, this is superb. I'm a former broadcast engineer and your design, build, LABELING, documentation are all excellent. You claim you're not an engineer, but I would argue that the way you attack the problem is exactly the way a good engineer would. I hope in future videos we can hear and see a waterfall demonstration of the S/N as well. 73 OM

Thanks again Steve. I would be interested in seeing how the KMTronic relay units compare with the Denkovi. I took a severe close lightning hit that damaged my Denkovi board this past Summer, killing my usb ports on the main computer. As you stated, there were some suffer points along the way getting the Denkovis configured. Boxes on the LAN may be a better solution. ~N8UX

very interesting, thanks for sharing.

Really appreciate these practical "How I did it" videos. Also apprciate you sharing what equipment you use to produce the tools.

Steve -love your very clear explanations and showing actual board/wiring harness layouts. Thanks for invaluable knowledge share. VU2XE

Great stuff.

great material, Steve. As always! Some people call that VLB (Very Low Beverage) too .
