DIY TV Antenna
I built this DIY antenna out of an old coax cable. I used some garden snips to cut off one end and strip off the shielding (I don't recommend you do this, it's tedious as fuck and you gotta be extremely careful not to cut off the copper bits) and arranged the copper into a dipole.

I can only get 1 channel with this antenna, as this thing can only pick up stuff VHF transmissions that are really strong. I've tried repositioning the copper elements to better receive signals to no avail. This pic is my third version, the copper is bent to try and make it a bowtie.

I'll buy an antenna on Amazon, but I would still love advice on how to improve this antenna I made, namely increasing it's effectiveness and picking up UHF signals. I can only do suggestions that can be done easily at home, no power tools, additional devices to buy, etc. Preferably something with aluminum foil and cardboard.

If you're close to broadcast antennas, use an attenuator. If you're far from broadcast antennas, use a unidirectional antenna like a Yagi with a signal booster for DTV signals. If you're close to a cell tower, use a LTE filter. If you want to make your own antennas, use a wavelength calculator and start with copper foil tape on cardboard or plastic, with a 75-Ohm to 300-Ohm matching transformer.

I made one of these out of scrap romex, a 2x4, and a balun a found.
