PROGRESS IN ENGLAND.

DISTANCES OP TRANSMISSION

High-definition television, which has a, range of five to si , : miles, is practically ready for commercial use in England, according to Mr. H..M. Dowsett, research, manager for the Marconi Telegraph Co., who is passing through Auckland. Lowdefinition television of the "head and. shoulder" type, he said, could bo sent on longer wave lengths, which would carry it much further than high-defini-tion. It could be used up to about 100 miles. Mr. Dowsett explained that highdefinition television which would photograph groups was only possible for transmission over a limited distance, ultra short waves being the medium. The transmission was only as far as a person could see on a clear day. It was what was known as an optical range, because it was limited to transmission on the very short waves, and could not "bend" around obstacles. "To begin with', television installations will be expensive," said Mr. Dowswtt, "but as time goes on the costs will come down. The television equipment cost will have to be- added to the cost of a iirst-c":ass receiving apparatus. Progress made has been remarkable, and at the same time steady."
