I love watching this video once in a while. It cheers me up! Thanks chap!

Nice point about the L-match especially. Very simple, very easy to understand, thanks, 73.

Helpful video. Thank you for sharing, Mr. Cecil B. DeSponge! ;-)

You should teach this stuff at Ham College! Very informative!

Hey there mate, So i´m fairly new to the antenna stuff, i do however find it highly intriguing.

Being a Ham of Scot-Irish descent I can understand Angus. I myself run HF QRP which keeps the cost down. An IC-720a at QSO would require something more substantial than the $13 USD T-match Chinese "Days" manual ATU kit I build (<15W max). His best bet for his budget would be a used MFJ manual ATU feeding a home brew multi-band antenna.

Sir, please tell me the design equations of L match for impedance calculations

What about the link coupled tuner?

nice one !

Hey , I have been watching every single possible video on antenna tuners that I can find in order to understand everything I can about this devices, I have a modem receiver that have this single wire antennas that come with a ATU unit "Two of them" each have a this totally miniaturized version of it.. but range on this particular unit really stinks. Now its my hope to increase the range by installing a good set of choked dipoles but don't know if I have not other choice but to use the same type of ATU? with the same value on the capacitors & inductor....your advice will mean the world to me!!

There are many different kinds of Tuna's.

a good mag loop can be made for the price of a tuner.... and it tunes.

I'm liking the scissors :) , anyway ...maybe get Angus to wind a toroidal balun match to get the high impedance to 50 ohms :)

To NAYJL1975: I can't approve your comment for some reason the 'approve' box is greyed out. I can't find any info on your RX tuner. The difference between a transmit tuner and a receive tuner is the the transmit tuner components are rated for high voltages. There's no high voltages present in a receive tuner so the capacitors have small spacing between the plates and band switches etc aren't usually suitable for the voltages present when connected to a transmitter. That said, 10W isn't much power. You could always try it and see, maybe start with 1W and if all is well increase the output power 1W at at time until you get to 10W. If the tuner is unhappy the radio will show intermittent high SWR and fold back the output power so you shouldn't see either unit damaged. Try this at your own risk, but that's what I would try.

Actually, the pair of scissors shtick at the very end of the show here is not a joke.

Compare to a perfectly build matched antenna (50 Ω)where you don't have to use any of the matching mechanisms ... Do you lose any energy or do you have any disadvantages in transmitting by having any of the tuners/matchers attached to a lets say (260 Ω) antenna ? ... thank you

Shunt / Hairpin Match?

Howdy. I believe VK6CS is right.

With the L tuner Angus could save the switch by changing the input - output cables...
