This is a simple functionnal HDTV Antenna.

I used "100mm x 5M Pure Copper Foil EMI Single Side Conductive Guitar Shielding Tape" for the copper part. You can get that at ~10$ on banggood. Aluminium foil and glue stick will work as well, but will be a bit harder to cut right.

I suggest you cut off the small index pins if they don't work. Screw fit will be more than enough to keep everything straigt,

Use M3 screws that fits, I used M3x18.
You also need a 75 to 300 Ohm UHF/VHF Matching Transformer. Which you can get for a buck,

Another way to add the conductive copper layer is via plating. I found out a few weeks ago that using conductive paint and brush plating solutions you can plate printed plastic. This would provide a consistent finish for something like this and would likely conduct more effectively but I can't be sure.
