Hello Guillermo, and welcome  :)

Get an FT-140-43 toroid core and a 100pf 3000V capacitor, some 1mm enameled magnet wire...
Use a 67ft antenna wire.

Then see the photos below:





The box above is a Hammond 1594B.

Gil.

Thank Gil !!

I have a doubt you say FT-140-43  but in the picture es FT 240-43.

Supourse that de only diference is the size ?

Don't need tuner?

Thank you

Hello,

Yes, the difference is the size. The 240-43 is a bit more efficient but much bigger. I use the 140-size. No tuner needed on 40/20m, maybe on 30.

For my MTR is use this to check SWR:

If the LED is not full-bright, you're ok.
