Ch 3: The Effects of the Earth (Feedpoint impedance vs height, losses, effect on radiation pattern). Ch 4: Antenna System Planning and Practical Considerations (Antenna and feedline construction, visibility, folding and shortening, etc.). Ch 5: Loop Antennas (large and small loops, loop skywire, etc.). Ch 7: Multiband Antennas (End-fed, centre-fed, G5RV, Windom, Parallel dipoles, Off-centre fed dipoles, Trap antennas, verticals, Discone antennas, etc.. The prolem of lack of harmonic suppression in multiband antennas.). Ch 9: Broadband Antenna Matching (Feedpoint resistance vs height for resonant antenna, loss, complementary RLC network, thick radiators, stagger tuning, parallel tuned circuits at the antenna terminals, broadband matching network design, transmission-line resonators, etc). Ch 16: Mobile and Maritime Antennas (Short loaded verticals, capacitance and radiation resistance, loading coil design, ground loss, efficiency, impedance matching, etc.). Ch 20: Antenna Materials and Accessories (wire types, wire tables, splicing, insulators, halyards, aluminium tubing data, plastics). Ch 22: Antenna Supports (trees, masts, halyards, wind compensation, guys, towers, etc.). Ch 24: Transmission Lines (basic theory, losses, SWR, impedance transformation, the transmission line equation for lossy lines, line construction, coax cables, line data, connectors, etc.). Ch 25: Coupling the Transmitter to the Line (Example input impedance data for realistic 30.5m straight and 20.1m inverted V dipoles with transmission lines. Discussion of harmonic attenuation in antenna tuners [pointing out that it is not reliable!], and the problem with trapped antennas. Ch 26: Coupling the Line to the Antenna (Broadband matching transformers p15-16. Common mode transmission line currents p16-20. Baluns p20-25.). CD ROM: TLW (Transmission Line for Windows).
