This is my first Instructable so please provide constructive feedback.
Be careful when working with the metal and use safety gear when needed. There are many sharp pieces when building this antenna.
Step 1: Planning
Step 2: Tools
High temp soldering iron with broad tip
Ruler or tape measure
Eye protection and gloves
Step 3: Using the Template
When printing this just make sure you scale to media.
Using The Template
Cut to fit inside the tin. Notice that it doesn't cover the entire surface and that is ok. You will cut to sides out and color in your cut out.
Step 4: Cutting the Tin
Notice that my two sides are a bit uneven (I eyeballed some of the rough template) but you shouldn't have this problem if you use the pdf template attached.
Step 5: Preparing to Attach the Coax
Make a bracket to hold the coax from scraps of the tin you cut out.
I can't recommend sanding the entire tin and any pieces you attach enough. If you do not the solder will not hold as well.
Step 6: Finished & Closing Notes
I am tossing around the idea of coating this with rubber so it looks more like a store bought product.
