Nautel Presents NEW Concept for Antenna Couplers!

Dayton, Ohio, June 8, 2004 - John Pinks, Chief Engineer (Emeritus), Nautel Limited, will release his white paper “Development of an Antenna Coupler that Fully Compensates the Deficiencies of Electrically Short LF/MF Antennas” at the ION 60th Annual Meeting.

The technical paper looks at how the improvements in transmitter technology have made them more susceptible to the effects of impedance mismatch. It then describes the development of a new antenna tuning unit which automatically adjusts both the loading coil impedance and the resistive matching network to maintain terminating impedance over wide variations of antenna characteristics.

The aim is to reduce field strength variations and increase confidence level in meeting required range and signal availability. The presentation is scheduled for Session E3, 1:00 p.m. to 4:00 p.m. Wednesday, 8 June 2004, Grand Ballroom E, Marriot Hotel, Dayton, Ohio.
