DIY VHF Antenna Tuner made from junk

Here's an interesting VHF "tuner" project from "crookedninja5."

This tuner can be made for almost nothing, depending on how much material and old radio parts you can find in your "junk box."

Here are some comments and suggestions from the author:

I needed something to make my clothes hanger antenna a little more broad-banded in the 100-200 MHz range, so I made a simple antenna tuner from junk... this would work for scanners too.... The variable capacitor can be any 0-365 pf capacitor... for c1 and c2 a ceramic or trimmer capacitor can be used... c3 and the coil is all you really need... About 8 or more turns on the inductor coil with taps spaced out every other turn. The rotary switch is from a old indoor antenna... everything in this vid was from a junk box, except for the RadioShack enclosure. Once you get the right combination of coil inductance and capacitance you'll see a difference it makes to your signal reception. This setup can also be used for SWL in the 3-30 MHz range with a 1" diameter coil of 120 turns and a random wire antenna! The bigger your coil the lower you can go!

Thanks for joining us today.
