Log-Periodic Antenna Design

Have you ever tried to get a clear picture, "next to the TV transmitter station"? The radiation pattern on the transmitting antenna leaves almost no signal in the shadow of the tower. I had to point the OTA antenna towards another tower a half mile away to get enough signal to monitor the 5 MW EIRP signal at the Channel 55 tower in Orange City, Florida. People within a half mile of the tower base couldn't get a clear signal.

Too late! ;-) I've already made the "coat hanger" four-bay bowtie, but with weld rod rather than hangers. ;-)

It was on youtube:

Yep, it's all about the antenna. Hell, even a dipole tuned to the midpopint of the band used for HD would get better performance.

As an independant producer and start-up would be very responsive and appreciative of your support and queries. Can aslo locate front end amplifiers inside anna eleiminating front connector loss. that last .035 db is hard to obtain any othe way with a connector beween any antenna and front end so we put front end inside anteanna substrate and your system will out perofrm all otthers!
