Dwight Isbell was a radio engineer, I.E.E.E antennas and propagation fellow, and co-inventor of the Log-periodic antenna while a student at the University of Illinois under Raymond DuHamel.[2] The log periodic antenna made possible broadband reception of color television signals. He is notable for the invention of antenna, and the resulting lawsuits regarding the antenna.[3]

The invention of the antenna and the patents were widely ignored by Channel Master and Blonder-Tongue, and resulted in the precedent setting Blonder Tongue doctrine of "Judicial Economy" which bars defendants of patents from that have been previously ruled invalid (changing the Triplett v. Lowe precedent).
