You can use this data with TLW to experiment with realistic situations and to gain familiarity with the program. Later in this document there are two tables of typical impedance data for two types of antennas. The user must be familiar with the so-called rectangular representation of complex impedance, in the form Z = R ± j X. TLW does assume that the user has some technical knowledge about transmission lines and antenna tuners. Then reboot your computer (if necessary), and exit by clicking on the OK buttons until you can exit the Control Panel folder.Ī Short History of the TLW Program TLW, short for 'Transmission Line for Windows' started out life as TL, short for just 'Transmission Line.' TL was replaced by TLA, short for 'Transmission Line Advanced.' The core algorithms in TLW have been under development, intermittently, for more than 10 years and the program has developed into a sort of 'Swiss Army Knife' for transmission lines and antenna tuners. Next, click on the Advanced button and select 'Large Fonts' in the Font Size list box. Choose either 800 × 600 or 1024 × 768 in the Screen Area list box. To set the screen size from the Windows Desktop Taskbar, select Start, then Settings, Control Panel, Display and then click on the Settings tab. These higher resolutions are best viewed with 'Large' font size. Note that a screen resolution of 800 × 600 or even better yet, 1024 × 768, will result in easier-to-read windows. The processor should be at least a Pentium 90 MHz, with at least VGA 640 × 480 screen resolution (with 'Small' font size, so you can see the whole window), 24 MB of RAM (32 MB for Windows 2000) and a CD-ROM.

Computer Requirements The minimum requirements to run TLW (and its companion program YW, Yagi for Windows) are a PC running Windows 95 or later, including Windows 98, Windows XP and Windows 2000.
Many users during the beta testing phase successfully navigated through all of TLW's many features without the benefit of an instruction manual.Ĭonsider the advantage you have, dear reader, since you are now reading the instruction manual! Version 2.0 now includes additional graphing capabilities described below.
