    This paper describes a simple technique using the SCA (Subsidiary Communications Authorization) channel authorized for use in FM and TV broadcasting to provide a one-way digital transmission channel for teletext-type service. The channel is transparent to data format. Preliminary field test results for a 9600 bit/second channel are also presented which show average error rates of less than 1 in 10... View full abstract»

    Relatively few types of variable power division circuits have been used in medium wave directional antenna feed systems, most of which suffer phase variation as the power division is adjusted. This paper discusses a class of circuits which can be used to implement a phase invariant adjustable power divider. Also discussed are variable phase shifters which have limited effect on power distribution.... View full abstract»

    A study of a circularly polarized (CP) television multiple antenna installation shows that improved measurement and theoretical techniques are required to model the scattered horizontal pattern circularity and video response in a candelabra. Previously developed guidelines for horizontally polarized antennas in a candelabra are inadequate to describe the expected performance of CP antennas in the ... View full abstract»

    Described here is a measuring system using a computer controlled network analyzer that allows observation of FM and TV broadcast antenna systems. Impedance measurement may be made at any point in a broadcast antenna system where access is possible. Most notably, the VSWR characteristics of an antenna on a tower may be measured from the ground without the effects of the transmission line. Measureme... View full abstract»

Aims & Scope

The Society’s Field of Interest is “Devices, equipment, techniques and systems related to broadcast technology, including the production, distribution, transmission, and propagation aspects.” In addition to this formal FOI statement, which is used to provide guidance to the Publications Committee in the selection of content, the AdCom has further resolved that “broadcast systems includes all aspects of transmission, propagation, and reception.”
