Build your own HDTV TV Antenna to cut the cord from your cable provider and save $1000 a year. This DIY antenna is very easy to build with just a few basic tools and a few supplies available from the hardware store.
After being disappointed with the current channel offerings and ever increasing price of our local cable provider, we recently decided to disconnect our cable TV service and go for over the air broadcasts as well as the many online services available now. I built this DB4 antenna, also called a bowtie antenna, to increase the rang of signals I could pick up over the basic rabbit ears antenna.
I switched back to Knoppmyth a couple months ago for my MythTV fix and I’m pretty happy with it except for a few minor glitches I’m still trying to work out. One of those glitches is that sometimes when the backend gets busy the video can become choppy and sometimes even effect the video as it’s written to the disk.
