  Biography - Ted Hart
  
  Written by Ted Hart
  ...
  Ted Hart Ted became a Ham (W5QJR) in 1948 and was assigned a JA call as part of the Occupational Forces of Japan in 1950.Unfortunately, he was sent to Korea before the license was issued.He is also licensed as TA2TGM as a result of engineering activities in Turkey.Ted has traveled extensively as an Electronics Engineer for Collins Radio, Omega T Systems, Scientific Communications, and the Harris Corporation in association with satellite communications and electronic intelligence systems.Now he travels for his own company developing applications of the EH Antenna.
  
  After retirement in 1996, Ted formed EH Antenna Systems to develop the EH Antenna concept.
  ...
  Ted has numerous patents, but most belong to the companies he worked for except the big one that got away because it was ahead of its time.The Collins Radio Company could not see a use for an "Infinitely Variable Pulse Width Generator" that was developed for telemetry to a radio controlled airplane (another hobby), so Ted entered the design in Electronic Design Magazine in 1964 and won the idea of the year award in international competition.Others saw use for the circuit - currently used in all power supplies and many other circuits where there is need to convert analog to digital signals.
  
  Continuously active as a Ham, Ted bought a farm in Georgia where he planned to grow large Ham antennas after he retired.

  More Setbacks for CFA, EH Antennas - [Cached Version]

  "The mistake was due to the use of a network developed for the HF version of the EH Antenna (a dipole), which has a high radiation resistance and low capacity," stated Ted Hart, chief executive officer of EH Antenna Systems on its Web site.
  
  "The AM broadcast antenna had low radiation resistance and high capacity.Unfortunately, until the test at the radio station, we had not applied transmitter power, thus the inefficiency was not evident."
  
  Hart posted details about the initial test, conducted in October, on his Web site at www.eh-antenna.com
  
  Hart told Radio World that a new, quarter-scale design was to be completed by the end of November.The design is intended to improve the match between the transmitter and the antenna.The result should be a full-scale antenna on which new tests will be performed.
  
  "We expect … final field tests in early December," Hart said.

  Meanwhile, delays plague the other AM antenna under development, the CFA antenna project in Shropshire in the United Kingdom.

  EH Antenna Systems President Ted Hart said the antenna could be placed on a building or free-standing tower.He met with FCC officials last fall regarding the certification process.
  
  "We have had good conversations with (the FCC).They agree that it works, but they are not sure about my theory since it doesn't comply with classical theory," Hart said.
  
  Hart said plans call for building an EH antenna in Williams, Ariz., after the FCC issues a construction permit, which it is expected to do later this spring.
  
  "The FCC will require full radiation tests on the first few antennas we build before issuing blanket certification," Hart said.
  
  His latest version of the EH antenna, called "Star," measures just eight inches in diameter and is less than 10 feet long, he said.
  
  Hart will present details during the "Radio RF and Transmission Development" session at NAB2004 in Las Vegas.
