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)
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 ;)
