Thank you for your kind words. A lot of experiments over the years prompted this video so I could share my findings. Take a look at the other videos on my UA-cam channel to see some of my other creations.
Excellent explanation of the different antenna tuner setups! You make a good point about ladder line in the wind; I used to use a G5RV, but high winds would make the ladder line dance, and the SWR would be all over the place. I enjoy your videos, thanks!
What I've been looking for, and continue to look for is a good explanation of which types of antenna tuner should work best under what sorts of conditions, meaning WHY is there a variety of different antenna tuner designs and circuits. Which has an advantage over the others, when and why? I watch video after video of tedious explanations describing exactly how each of them is built and wired, but can't seem to find a single video that explains why I'd want one kind over another.
T network gives most range but also most loss Pi network gives less range and least loss L network is simplest with possibly the least range depending on configuration The type tuner that would be best suited for you really depends on several variables such as type of antenna length of antenna location of antenna type of Feedline etc I have done a lot of experiments over the years which has prompted this video Best advice I can offer is to try different setups and make observations and from there draw your own conclusions Nothing like finding out for yourself !
@@madeinfoxtrap5539, thank you for the summary. Those first 3 lines are exactly what I was looking for. Not just information, but useful information, understanding, guidance. I read and I watch videos precisely so I don't have to reinvent the wheel. As for me, I'm 72 and in a wheelchair, so a good starting point certainly beats me physically trying every conceivable combination of L and C until it starts making sense. It's what I read and watch videos for. I'm too old to spend my time rediscovering things that are already well known. I've already spent years of my life doing just that. But now I'm a shorttimer, so I no longer have the luxury of doing many things wrong. UA-cam has video after video explaining reactance over and over without ever actually leaving one more knowledgeable about what to do and why to do it, about the way these things interact and the results of the interaction. They leave out the, "And in conclusion..." or, "And here's what that all means..."
The 1:1 balun (balancing transformer) 10 double turns of #16 AWG magnet wire (varnished factory coating) The inductor and capacitor were both bought second hand and I believe the capacitor was 340uF and the coil I’m not sure maybe 60uH Built a few years back. Larger the value of these components will determine the range so try to find the higher value components. Not necessarily monetary value but value of capacitance and inductance ! Thank you for watching !
@@architetturaearte you may use whatever you can find. It will work. Both components can be adjusted to almost zero so Use the highest value of components. Highest capacitance and highest inductance will give you the best range. Try to have your Antenna a resonant length to the lowest frequency that you use so the tuner is only just fine tuning and balancing
Hi! Thanks for a nice video! A T-network offers a wide range impedance matching with relatively small capacitor values and it is simple. But... It doesn't offer the bandpass or low pass filtering sometimes needed for SWL:ing and qrp ham gear. 73 de OH8UBJ
Very inspiring for an amateur. I appreciate the effort and sharing of real life - practical - experience in these tuners.
This was really helpful, thanks. It filled some gaps in my knowledge.

Very nice to see your construction as a guide for my own build.
Thank you. I’m glad I’ve inspired you to build your own or at least helped These circuits are not complicated at all. Good luck 73
Fantastic video, been long time since had to know difference in tuners, great explanation!

Great Video ! Thanks for posting ! With the holidays coming up perhaps I can accumulate a few proper cookie tins
Thanks for the video!
Great info on tuners . Well made tuners Thanks .
Our you tube channel is INKITS 👍
Cool stuff dave
Good info ♥
great video om. keep em comin'

Looking for this vdo.
It is possible to know the value of roller inductor and variabile capacitor of "L" network? For the balun instead? Many thanks in advanced

The inductor and capacitor were both bought second hand and I believe the capacitor was 340uF and the coil I’m not sure maybe 60uH

@@madeinfoxtrap5539 many thanks for your answer. I'm interested to build It for the qrp use too. The value of the component are the same?

Use the highest value of components. Highest capacitance and highest inductance will give you the best range. Try to have your
Antenna a resonant length to the lowest frequency that you use so the tuner is only just fine tuning and balancing

Hi..I will only use it for listening sw..not for transmitting..which one is useful for me?
Either one will work but the T network will provide the greatest range for the value of the components used.

What type of tuner are the Johnson Matchbox's ? Thanks.
Link-coupled fixed inductor for balanced line.
What's the accent? I can't work it out.

Ah, interesting. I couldn't place it.
