    摘要: A combline filter has a ceramic resonator disposed inside at least one cavitywall. Because the resonator is implemented as a hollow rod, a tuning element may be inserted into an opening on 5 the top ofthe rod to tune its frequency. A mounting element, inserted into an opening on the bottomofthe rod secures its position inside a cavity resonator. Instead of soldering the resonator to the filter’s walls, the resonator is supported above a bottom or side wall of the cavityresonator.

    摘要: A novel locking mechanism for mounting a radio to an antenna. The mounting face of a radio is secured to the mounting portion of an antenna. The mounting portion of the radio has a locking ring on which a plurality of radio locking tabs are located at equally spaced positions. The ring can be fixed to the radio, or in another embodiment, is still secured to the radio but can rotate independently. The mounting portion of the antenna has a corresponding number of equidistantly spaced tension springs, which have a plurality of spring fingers. To mount the radio to the antenna, the radio locking ring with radio locking tabs is twisted so that each antenna tension spring is deflected by a corresponding radio locking tab. The engagement of the radio locking ring to the antenna spring fingers secures the radio to the antenna. The deflection force also produces a friction force. The spring fingers allow the deflection and friction forces between the tension spring and radio locking tab to increase step-wise when the radio locking ring is brought into contact with each additional spring finger. This step increase in forces allows a user, when turning the radio, to overcome the forces of each spring finger individually, instead of having to initially overcome both sum forces of one solid spring.
    When the adaptation of the rotating ring is used and additional polarization feature, is possible that prevents the incorrect polarization installation of the radio and antenna assembly by the user.

    摘要翻译: 一种用于将无线电安装到天线的新型锁定机构。 收音机的安装面固定在天线的安装部分上。 无线电装置的安装部分具有锁定环,多个无线电锁定突片位于该锁定环上,位于相等间隔的位置。 环可以固定在收音机上,或者在另一个实施例中,仍然固定在无线电上,但是可以独立地旋转。 天线的安装部分具有相应数量的等距间隔的张力弹簧,其具有多个弹簧指。 为了将收音机安装到天线,具有无线电锁定片的无线电锁定环被扭曲,使得每个天线拉伸弹簧被相应的无线电锁定片偏转。 无线电锁定环与天线弹簧手指的接合将无线电固定在天线上。 偏转力也产生摩擦力。 弹簧手指允许当无线电锁定环与每个附加的弹簧手指接触时,拉伸弹簧和无线电锁定片之间的偏转和摩擦力逐步增加。 这种力的增加允许用户在转动无线电时克服每个弹簧手指的力而不是首先克服一个固体弹簧的总和力。 当使用旋转环的适配和附加的偏振特征时,可能防止用户对无线电和天线组件的偏振安装错误。

    摘要: This invention relates to a tapered slot antenna with broadband characteristics whose beamwidth is stable over both the PCS (1850-1990 MHz) and the cellular bands (824-894 MHz). In a first preferred embodiment, a dual band antenna is disclosed which uses a single column elliptically shaped Vivaldi notches (12, 13) as the radiating elements. In a second preferred embodiment, a dual band antenna comprising elliptically shaped Vivaldi notches (12, 13) and sub-reflector positioned between a main reflector and the dipoles is disclosed. This resultant antenna produces a stable, ninety-degree beamwidth with a bandwidth broad enough to cover the PCS and the cellular bands.

    摘要: A tower top amplifier for use outdoors in a radio frequency communications system has a surge suppression device for suppressing electrical surges caused by lightning strikes. The surge suppression circuit has a short circuit inductive coupling loop connected to a coaxial cable connector (102). By using a capacitor (110) connected in parallel with an inductive probe (114), the surge suppression circuit operates as an open circuit at the operating frequency of the system. In addition, at the operating frequency, the resistor (112) matches the impedance of the system connected to the coaxial cable connector (102). But in the event of a lightning strike or other electrical event, the inductive coupling loop short circuits the surge current to ground, thereby protecting the amplifier system from damage.

    摘要: An angle diversity antenna system utilizes a first antenna, a second antenna, and a panel combiner coupled to the first and second antenna. In a transmit mode, the first and second antenna are coupled to a transmit sum channel of the panel combiner. In a receive mode, either the sum channel or a difference channel of the panel combiner is chosen as the active channel. By monitoring the sum channel and difference channel, the antenna system according to the present invention is able to select the channel which supplies the greatest signal strength.

    摘要: This invention relates to an improved coaxial cable preparation tool (1) that is used to prepare a coaxial cable terminal end for connector installation. The tool comprises two stages. The first stage (10), the jacket stripper, is used to trim the cable jacket. The second stage (20), the cable trimmer, is used to trim the remaining center, the outer conductors and the foam insulation of the coaxial cable. The first stage (10) consists of a cup or cylinder (11) with an outer cylindrical wall (12). In addition, it also comprises a blade (13) and a scrap port (14). In addition, the first stage cylinder (11) has a bore (16) extending axially down its center. The diameter of the bore (16) is set to receive a coaxial cable. The second stage consists of a hub (21) (or cutter head), a collet bearing (22) and a body (23). In addition, like the first stage, it also contains blades (13) and scrap ports (14). The scrap ports or debris ports (14) allow trimmed cable media to escape from the bores in the tool.

    摘要: A system for inductively cross coupling resonators. Two resonators are interconnected by a cross coupler with the two ends, each end having a hole. The holes secures each end of the cross coupler to one of the resonators. The use of a stamped piece as a cross coupler results in a repeatable placement between resonators that minimizes any variation in coupling between resonators due to human error during assembly. This repeatability reduces assembly time and assembly cost.
