Noll","description":"\r\n73 Vertical, Beam, and Triangle Antennas by Edward M. Noll (160 pages). This is a fantastic book that covers all aspect of building your own antenna setup.\r\n\r\nFrom the Preface:\r\nAn often-heard comment of the present is: “The days of amateurs building and operating their own equipment are a thing of the past.” To a great extent this is true, since the advent of sophisticated single-sideband equipment has convinced many hams that construction of their own gear is no longer practical.\r\n\r\nThe one big exception to this is in the field of antennas. The amateur, at very little expense and without the requirement of an R\u0026amp;D laboratory, can indulge in experimentation with antennas, sometimes with startling results.\r\n73 Vertical, Beam and Triangle Antennas is the second of a series of books which can make the hobby of amateur radio more than an operational spectator activity. Each antenna described in this book was constructed by the author without assistance. A minimum of tools and equipment were used. You can do the same and use the world as your testing ground.\r\n\r\nMany of the antennas described in this book compete with, and sometimes surpass, the performance of commercial beams. A number of new approaches in the construction of basic antenna types are detailed. The book is not so much a rehash of common antennas and basic theory as it is a coverage of new approaches and ideas not often used by the amateur.\r\n\r\nThere are 73 individual vertical and beam antennas included in an order that begins with simple construction and progresses in a sequential manner to more complex arrangements. However, if you are interested in only one particular type, you can locate that type immediately and proceed with its erection.\r\n\r\n73 Vertical, Beam, and Triangle Antennas is an invitation to some inexpensive education and fun. You will find it very educational and satisfying to put up an antenna that you have calculated, erected, and tuned. You have also gained a conversation peak that can bring you that much nearer to other radio amateurs all over the world. There are very few of them who are not interested in antennas.\r\n\r\nContents\r\n\r\nPreface\r\n\r\nSection 1: Quarter-Wave Verticals\r\n1 - Half-Wavelength Dipole (Hertz)\r\n2 - Quarter-Wavelength Vertical (Marconi)\r\n3 - Quarter-Wave Vertical, Line-Tuned\r\n4 - Quarter-Wave Vertical with Ground System\r\n5 - 10-15-20 Quarter-Wave Vertical Wand Ground System\r\n6 - Elevated Quarter-Wave Vertical with Wire Ground Plane\r\n7 - Base-Loaded Quarter-Wave Vertical\r\n8 - 20-Meter Quarter-Wave Vertical, Multiband Operation\r\n9 - Elevated 40-Meter Ground Plane\r\n10 - Vertical Radiators and Base Tuner\r\n\r\nSection 2: 1\/2- and 5\/8-Wavelength Verticals\r\n11 - Half-Wavelength Verticals\r\n12 - Half-Wave Vertical and Balanced Line\r\n13 - Half-Wave Coaxial Vertical\r\n14 - 5\/8-Wavelength Vertical\r\n15 - Three-Quarter Wavelength Vertical\r\n\r\nSection 3: Phased Verticals\r\n16 - Quarter-Wave End-Fire Pair, 90°\r\n17 - Quarter-Wave End-Fire Verticals, 180°\r\n18 - Quarter-Wave Broadside\r\n19 - Multiband Broadside with Tuner\r\n20 - End-Fire Broadside Combination\r\n21 - Closed-Space End-Fire Vertical\r\n22 - Elevated Two-Element Phased Verticals\r\n23 - Four-Element End-Fire Broadside\r\n24 - 20-Meter End-Fire (180°), Broadside Combination\r\n25 - Eight-Element 10-Meter Vertical\r\n26 - Four-Square Verticals\r\n27 - 10-15-20 Four-Square Vertical\r\n\r\nSection 4: Low-Band Verticals and Inverted Vees\r\n28 - TV Mast 80-Meter Vertical\r\n29 - Low-Band Vertical with Line or Base Tuner\r\n30 - 80-160 Vertical\r\n31 - 40-80 Vertical\r\n32 - Low-Band Vertical with Gamma- and T-Matching\r\n33 - Short 160-Meter Vertical\r\n34 - Low-Band Inverted Dipoles\r\n35 - Inverted-Vee Antennas\r\n36 - 40-80-160 Inverted Vee Antenna\r\n37 - Three-Quarter Wavelength Titled Inverted Vee\r\n\r\nSection 5: Two-Element Parasitic Antennas\r\n38 - Parasitic Reflector, Wide spaced\r\n39 - Parasitic Director, Wide Spaced\r\n40 - Two-Element Parasitic Antenna, Closed Spaced\r\n41 - Closed-Spaced Two-Element, Stub Matched\r\n42 - Parasitic Reflector-Director Combination\r\n43 - Inverted-Vee Parasitic\r\n44 - Multiband Inverted-Vee and Parasitic-Element Combinations\r\n45 - Single-Mast Inverted Vee with Parasitic Element\r\n46 - Acute-Angle Vee with Parasitic Element\r\n\r\nSection 6: Horizontal Phased Arrays\r\n47 - Horizontal End-Fire, 90° and 180°\r\n48 - Broadside and Collinear Two-element Horizontals\r\n49 - Collinear, End-Fire (180°)\r\n50 - End-Fire (90°), Broadside\r\n51 - End-Fire Beam\r\n52 - 10-15 End-Fire Beam, Open-Wire Line\r\n53 - Stacked 10-15 End-Fire Beam\r\n\r\nSection 7: Yagis, Quads, and Triangles\r\n54 - Three-Element Yagi, Stub-Matched\r\n55 - Three-Element Yagi, Open-Wire Line\r\n56 - Multielement Yagis\r\n57 - Stacked Yagis\r\n58 - Two-Band Inverted-Vee Yagi for Low Bands\r\n59 - 10-15 Three-Element Yagi\r\n60 - Two-Element Quad\r\n61 - Two-Element Quad, Tuned Reflector\r\n62 - Two-Element Quad, Stright Reflector\r\n63 - Two-Element Quad, Director\r\n64 - Three-Element Quad\r\n65 - Two- or Three-Element Quad, TV-Line Feed\r\n66 - Multiband Quad\r\n67 - Low-Band Triangle\r\n68 - Triangle and Parasitic\r\n69 - 160-Meter Two-Element Triangle\r\n70 - 40-80 Three-Element double Triangle\r\n71 - Single-Mast Triangle and Parasitic\r\n72 - 80-Meter Triangle with Ground Radial System\r\n73 - Triangle Turnstile\r\n74 - 15-, 40-, and 80-Meter Triangles\r\n75 - High-Band Triangles\r\n\r\nAppendix I - Antenna Noise Bridge\r\nAppendix II - How to Measure the Velocity Factor of Transmission Line with a Noise Bridge\r\nAppendix III - Cutting Half-Wave Sections of Transmission Line Using the Antenna Noise Bridge\r\nAppendix IV - Measuring the Rest Frequency and Resistance of an Antenna With the Antenna Noise Bridge\r\nAppendix V - Cutting an Antenna to Resce Using an SWR Meter\r\nAppendix VI - The Construction and Tuning of a Line Tuner\r\nAppendix VII - Antenna Tuner for Long-Wire Vees and Rhombics\r\nAppendix VIII - Base Tuner for Vertical Antennas\r\n\r\nThe original book was scanned and converted into this digital file in Adobe Acrobat .pdf format.
