Whether through choice or circumstance, more radio amateurs than ever before are enjoying portable operating. Suitable equipment is widely available but what about antennas? Manufactured antennas exist but only some suit lightweight portable activity. And, it's easy to overpay for something that's too heavy and too lossy for successful QRP. Hand-carried QRP antennas takes the mystery out of portable antennas. After inviting you to assess your needs, it discusses the pros and cons of popular types. Its style is brisk and practical with almost no maths. Many ideas for cheap but good materials suitable for portable antennas are given. Beginners and those returning to radio after a break should especially find this section handy. Finally there's construction details on a variety of simple but practical antennas and accessories suitable for portable operating. All have been built and tested by the author over almost 30 years of successful QRP activity. Hand-carried QRP antennas is the author's second book, following on from the top-selling Minimum QRP, released in 2015.

Minimum QRP is full of ideas for the radio amateur who wants to get the most from their modest station and antenna. Apply its tested strategies today for more success on the bands, whether you're into portable operating, DX, awards, contests or more. While pitched at the QRPer, those with 100 watts and simple antennas will also find much of interest. It's for a broad audience, including newcomers, the more experienced and those returning to amateur radio. After touring various facets of QRP, Minimum QRP gives some forthright but often forgotten advice on equipment. Is the commercial, kit or homebrew transceiver you're considering sufficient to give spontaneous contacts almost any time you switch on? This book guides you through the choices out there, with an emphasis on affordable and effective. Antennas are next. One size and type does not fit all. The right choice depends on location, style of operating and activity patterns in your area. Some suggestions, based on the author's extensive experience of restricted space and portable QRP, are given here. Some QRPers have suitable equipment and antennas yet don't make as many contacts as they should. Reasons for this can come down to choice of band, understanding local activity and operating technique. Whether you're after DX or a local ragchew, Minimum QRP gives some crafty tips on working the most with the least. Nearly every aspect of amateur radio can be done with five watts. Indeed QRP can sometimes add to its enjoyment due to simple to construct and lightweight equipment. If you get bored with one facet there's always another. You'll find information on such QRP sub-interests, such as weak signal modes, VHF and pedestrian mobile in this book. Still not sure? View some of the author's other material at http://www.vk3ye.com and http://www.youtube.com/vk3ye , With much new content, Minimum QRP consolidates the author's experience in the one reference. With over 200 pages and numerous illustrations it represents excellent value.

Joe Carr has provided radio amateurs and short-wave listeners with the definitive design guide for sending and receiving radio signals with Antenna Toolkit 2nd edition. Together with the powerful suite of CD software, the reader will have a complete solution for constructing or using an antenna - bar the actual hardware! The software provides a simple Windows-based aid to carrying out the design calculations at the heart of successful antenna design. All the user needs to do is select the antenna type and set the frequency - a much more fun and less error prone method than using a conventional calculator to solve formulae. The new edition has been revised to include further cases of propagation, additional antennas and also two new chapters - Small Loop Antennas (a topic of considerable interest, which has been the subject of much recent debate in the amateur radio press); and Yagi Beam Antennas (widely used at HF and VHF). The CD software has also been updated. Joe Carr's expertise in the area of antenna design is legendary. Antenna designers, whether hobbyist or technician, can be assured they need look no further than Antenna Toolkit for the complete guide to understanding the practicalities of using and designing antennas today. A complete solution for antenna design in one package. Includes free CD-ROM with state of the art software for all design calculations. The definitive guide to antenna design for radio amateurs and short-wave listeners.
