[TenTec] 160 M antenna

[Steve Hunt]

Rick,

That's correct!

The only published article I know of was by Tim Forrester G4WIM in 
RSGB's RadCom - later included in their book "HF Antenna Collection". In 
addition to the basic top-loading principle, Tim described in detail the 
mechanical arrangements for the auto tuning whip: a geared motor drove a 
lead screw that progressively introduced a core into the loading coil. 
Tim won an RSGB award for the article - the design was in many ways a 
forerunner of the "screwdriver".
