Antenna Reference App
This App provides a comprehensive guide to antennas with a good selection of antennas to consider for construction. As well as the common dipole, 'V', Quad, Yagi and vertical antennas there are many others. The Discone, Windom, Zepp and J-Pole, the X-Beam and ZL Special - just to name a few. Also included are typical radiation patterns for each antenna, a wide range of impedance matching methods and a table of specifications for different coaxial cables and wire.
The contents include basic antenna and propagation theory, transmission lines, and impedance matching. By providing measurements, built-in calculators take the guess-work out of antenna construction, impedance match design, and transmission line length.
Pictures, either photographs or line drawings, are included for each antenna so you can see what the finished product should look like.
There is a Data section which has tables of coaxial cable types, wire data for conversion between AWG and metric wire sizes as well as resistance values for ordinary copper wire. A quick explanation of the relationship between frequency and wavelength, and wiring diagrams for common connectors used in radio round out the content.
