    When two or more FM broadcast transmission systems share a cominon site with co-located antenna systems a degree of cross-coupling can occur between the systems. When this cross-coupling becomes excessive the transmitter final amplifiers can produce out-of-tolerance, non-harmonic related emissions. The frequencies, and amplitudes of these emissions are related to the frequency, and amplitudes of the cross-coupled transmission systems. View full abstract»

  • Intrinsic Average Power Limitation of Coaxial Transmission Line for UHF-TV Five Megawatt Operation

    The power handling capability of coaxial transmission line is intrinsically limited by the onset of the TE 1,1 waveguide mode. An expression is developed for this limitation as a function of operating frequency, and ramifications are examined for UHF-TV operation at the maximum licensure E R P of 5 Megawatts.

    Two computer programs have been developped for the calculation of the horizontal far field radiation pattern and the directivity of full wave dipole panel antenna arrays for the VHF TV Broadcasting. The programs are written in Basic and were run with the aid of a HP-86 personal computer. View full abstract»

    Reradiation of an MF/AM broadcast transmitter's signal by a power transmission line can cause serious pattern distortion. A computer model of a power line, developed and tested against scale model measurements over highly conductive ground, has been used to assess the pattern distortion to be expected from a power line proposed for construction, to identify those towers on an existing power line which carry strong RF currents, and to design "detuningn devices to suppress such currents. The accuracy of the computer model's "predictions" is tested in this paper against full-scale measured RF current flow on the skywires of a real power line. A toroidal current probe is described which is suitable in the MF band for current measurement on a large steel lattice structure such as a power line tower. Instrumentation is described for the measurement of either current magnitude only, or of both magnitude and phase. Thus the current flowing on a power line tower is readily measured by this method. Measurements of skywire current are compared with computations using a highly conductive "perfect" ground model, and using the Sommerfeld-Norton ground model for "lossy" ground of conductivity 10 millisiemens/metre and relative permittivity 15. The two ground models result in similar current distributions, with the peaks and minima in the standing wave pattern at the same positions on the skywire. The lossy ground model results in somewhat less current flow due to the damping introduced into the resonant behaviour of the power line. View full abstract»
