Homemade Coaxial Antenna Cable

Introduction: Homemade Coaxial Antenna Cable

About: a little heads-up: my earlier instructables might be badly written, as i wasn't very good at english back then

Hello yet again readers!

today i'll be showing you how to make some really simple homemade coaxial cable, for FPV antennas n' stuff.

but first, a bit of a disclaimer: i don't know anything about what makes antenna cable "good", but i see no reason why this wouldn't work fine.

Let's get started!

Step 1: Get Your Stuffs Together

Alright, so this is what you'll need:

a piece of solid copper wire. or in my case, .8 mm copper-coated MIG welding wire(that stuff's really useful)

electrical tape

copper foil tape. or i guess you could use aluminium tape, but then you wouldn't be able to solder it.

heatshrink tubing, or more electrical tape.

Step 2: Can't for the Life of Me Come Up With a Good Title for This Step

cut a piece of electrical tape as long as the copper wire, and about 1cm(~0.4") wide.

then roll it around the copper wire as tightly as possible.

Step 3: Copper Time.

now do the same thing with the copper tape.

what? not all steps have to be complicated.

Step 4: Adding the "heat" to Heatshrink

cut a piece of heatshrink tubing long enough to cover the whole wire, then do that.

or just use more electrical tape, that'd probably work fine.

Step 5: Aaaaand, That's It!

so, that's it. you're done!

i guess you could technically add as many layers of copper and tape as you want, so you could make a 42-layered cable and antenna to discover the secrets of the universe.

and if you do discover something interesting, leave a comment ;)

    Very creative and instructive. I'm the first to admit I know very little about this area but isn't using salvaged coax easier?

    Well, it would be. but i couldn't find any.

    Cool. I was just wondering. I'm still impressed with your creativity!
