    The design principles, construction, and performance of a ten-foot whip antenna for use with radio communication sets covering the frequency range from 30 to 76 MHz are described. The antenna is insensitive to changes in environment, with respect to electrical performance. It has uniform azimuthal distribution of radiation, optimum gain at the horizon, and is suited as an element of antenna arrays... View full abstract»

  • A new technique for measuring mobile transmitter noise spectra

    Publication Year: 1966, Page(s):48 - 56

    No reliable method of measuring absolute levels of noise close to the carrier of present day mobile radio transmitters has been available. The difficulty has been the large difference in levels of the carrier and noise. A new technique for measuring absolute noise power spectra near an unmodulated transmitter carrier has been developed. This technique depends on cancellation of the coherent carrie... View full abstract»

    It has been shown that Forward Acting Automatic Gain Control (FAAGC) is able to suppress the intermodulation (IM) products caused by rapid fading, particularly in the case of single sideband (SSB) transmission at UHF. Envelope detectors were used for simplicity, but since typical existing SSB systems use synchronous (or homodyne) detectors and a regenerated carrier, comparative analyses and tests ...

    Signal fading at 836 Mc on a mobile radio transmission path using directional antennas on the mobile unit was investigated and compared with that from an omnidirectional antenna. A marked reduction in fading rate was observed with the directional antenna. Increasing the directivity decreased the fading rate. The average propagation loss was also measured for the various antennas over the two-mile ... View full abstract»

    The technique described in this paper is classed as a near-field method wherein the measuring probe is located less than 5-feet from the interference energy source. It provides a means for expressing the magnitude of the interference energy in quantitative terms which are independent of the receiver and antenna characteristics as well as the propagation anomalies experienced in the field intensity...

    In order to realize its full utilization, two-way mobile radio must follow the people who use it into their working environment; thus, we find more and more radio-equipped people in subways, missile silos, serving the factory assembly line or reporting on convention proceedings. Similarly, radio-equipped vehicles such as subway trains and mine hoists, in a natural underground environment, are exam... View full abstract»

    Propagation experiments were run at 836 Mc between a fixed omnidirectional base station and a mobile station using a directional antenna. On typical residential streets it was found that the antenna orientation had only a small effect on the average signal level and that the fading rate was significantly reduced. It was also discovered that the fading rate expressed as a function of antenna direct... View full abstract»

    The design and performance of a series of three base station antennas employing the radiator-suppressor concept are presented. Two are for the 450–470 MC band, one having 7 db gain and the other 10 db gain. The third is a 6 db gain unit for 150–162 MC. The two medium gain units consist of end fed arrays, while the high gain unit is center fed. View full abstract»

    The multipath interference to FM transmission of television between vehicles moving over a flat Earth is analyzed. The paper starts with the derivation of the direct path and multipath signals. In this derivation an induction formula is obtained for the RF spectrum of a signal which is produced by frequency modulating with N modulating frequencies. It is pointed out that the direct path signal alo... View full abstract»

    An experimental investigation was conducted to determine whether the degradation in electrical performance commonly observed with reduced-height helical-wound vertical dipoles can be avoided. A new design approach has been explored which helped define a major cause of this degradation. Data obtained during this investigation supports a working hypothesis that losses associated with circulating cur... View full abstract»
