小功率的力量 [图书] 豆瓣
More QRP Power
作者: [美] 美国业余无线电转播联盟 译者: 赵辉 人民邮电出版社 2010 - 9
在业余无线电领域,通常把使用最高不超过5W的射频功率来进行的通信称为小功率通信,Q简语中用QRP来表示降低发信机功率,因此小功率通信又称QRP通信,它是业余无线电通信的一个重要分支。
很多QRP通信爱好者热衷于自制QRP设备,用自己的DIY作品通联全球。本书收录了美国业余无线电转播联盟(ARRL)两本著名的杂志QST和QEX中刊登的关于多波段QRP收发信机、电台辅助设备及小型天线的经典制作文章。相信这些文章将能够帮助QRP爱好者们把自己的小功率通信设备打造得更完美。
本书介绍的案例的作者都是QRP领域的资深专家,内容指导性强,非常适合业余无线电爱好者、从事电子设计的技术人员以及相关专业的师生学习和参考。

Practical Antenna Handbook 5/e [图书] 谷歌图书
作者: Joseph J. Carr / George W. Hippisley McGraw Hill Professional 2011 - 10
THE DEFINITIVE ANTENNA REFERENCE--FULLY REVISED AND EXPANDED! Design and build your own antennas with the help of this unique guide. Updated and revised to provide clear answers to questions frequently asked by hobbyists and electronics technicians, Practical Antenna Handbook, Fifth Edition blends theoretical concepts with hands-on experience--requiring only high school mathematics Reorganized to flow logically from broad physical principles to specific antenna design and construction techniques, the book begins by covering the fundamentals. Then the half-wave dipole is discussed both as an excellent antenna in its own right and as a conceptual tool for predicting the performance of other designs. Transmission line impedance matching techniques--and a companion Smith chart tutorial--lead into "must have" accessories for tuning, monitoring, and troubleshooting antenna system performance. Other tools, such as antenna modeling software and network analyzer add-ons for PCs and Macs, are addressed, and concluding chapters offer fresh insights into support structures and installation techniques. NEW TOPICS COVERED INCLUDE: Characteristics of all-driven and parasitic arrays Beverages and small MF/HF receiving loops Top-loaded shunt-fed towers and other verticals Theory and design of Yagi beams Effect of real ground on propagation and antenna patterns, impedance, and efficiency Lightning protection and four kinds of ground systems Zoning and restrictive covenants COVERS A WIDE VARIETY OF ANTENNAS: Dipoles and inverted-Vs Quads, delta, and NVIS loops Wire arrays (bobtail curtain, half-square, rhombic) Verticals and shunt-fed towers Rotatable Yagi beams MF/HF receiving antennas (flag, pennant, K9AY, Beverage) Mobile and portable antennas VHF/UHF/microwave antennas And many more GO TO WWW.MHPROFESSIONAL.COM/CARR5 FOR:
