    The fluctuations of radio signals at microwave frequencies on overwater paths are explained on the basis of a periodic rise and fall of the water level. From this study, it is seen that the variations in the radio signal strength will contain the frequency of the water-level cycles and also the second and third harmonics of the water-level cycles. This same model predicts that the cross-correlatio... View full abstract»

    A new type of endfire array is described which has moderate bandwidth in the vhf and uhf ranges. Two types of arrays are dealt with; one, an unbalanced type fed with a coxial line, which was studied primarily to test the theory of operation of the antenna; the other, a balanced type fed with unshielded twin-line, which was developed as a receiving antenna for vhf television. This latter antenna ha... View full abstract»

  • Radio transmission loss vs distance and antenna height at 100 mc

    This report describes curves of transmission loss vs distance and antenna height derived from an analysis of approximately 159,000 hourly median field-strength observations between 90 and 110 mc. These observations extend over a period of several years and are distributed geographically over the whole United States. The curves contained in this report are believed to be more precise for engineerin... View full abstract»

  • Spacing-error analysis of the eight-elemennt two-phase adcock direction finder

    Publication Year: 1955, Page(s):63 - 65
    Cited by:  Papers (1)

    In the design of a modern high-frequency radio direction finder utilizing the Adcock principle, the sensitivity and spacing error limitations of the conventional four-element array requires the use of several arrays in order to cover a large portion of the frequency spectrum. An eight-element array is described which has an operating frequency range considerably greater than that of the familiar A... View full abstract»

    Theoretical and experimental results obtained by Hartig for the end correction for a coaxial line when driving an antenna over a ground screen are corrected. Improved theoretical and experimental curves of the quantity -C_{T}/bc_{0} are obtained, where -C_{T} is the lumped negative capacitance required as end correctio... View full abstract»

  • The shielding of radio waves by conductive coatings

    Publication Year: 1955, Page(s):72 - 76
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (499 KB)

    A theory is given of the shielding of radio waves by the conducting coatings which are placed over the cockpit dome and windows of an airplane. At low and medium frequencies the shielding arises primarily from the quasi-electrostatic charges which are induced on the surfaces the effects of which increase strongly with decreasing frequency. At higher frequencies the shielding from this source dimin... View full abstract»

  • VHF auroral and sporadic- E propagation from Cedar Rapids, Iowa, to Ithaca, New York

    Publication Year: 1955, Page(s):76 - 80

    A 50-mc transmitter operating continuously at Cedar Rapids, to the west of Ithaca, has been monitored for more than two years, using a northward-pointing antenna intended to reduce signals from the west due to E -scatter and bursts due to meteors. Associated with visible auroral activity, enhanced signals are heard, having a very rapid fading rate, characterist... View full abstract»

    The conditions for endfire radiation from a traveling-wave slot are discussed. These are that the phase velocity of the traveling wave be equal to or less than the velocity of light in free space and that the aperture be excited with a strong longitudinal component of electric field. Practical ways of achieving these conditions are mentioned and an approximate analysis based on partially dielectri... View full abstract»

  • The various theories on the propagation of ultra-short waves beyond the horizon

    Publication Year: 1955, Page(s):86 - 91
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (531 KB)

    Three theories for the calculation of fields beyond the horizon have been reviewed. It has been seen that these theories rest on the instability of the propagated wave in respect various physical factors (meteorologicalor due to terrain conditions). It appears that the three methods, each having its own advantages, can be used jointly by engineers concerned with long-range communication. 1. Near t... View full abstract»
