• Dipole
• Fat Dipole
• Yagi
• J-Pole
• Super J-Pole
• Log Periodic
• Cubic Quad
• Vertical
• helical

It also performs the following calculations:

• Transmission Line Calculator
• Coil Design
• LC Filter Design
• Transmission Line Loss
• L Matching Networks
• Pi Matching Networks
• Impedance Calculations
• Wire Gauge and Resistance and Voltage Drop
• Wire Inductance Calculations

With the transmission line calculator, you can select the type of line, length, operating frequency, and calculate the losses, as well as the SWR and losses from SWR due to impedance mismatch. The load impedance can also be calculated from the measured impedance at the line input.

The cost of buying RF Toolbox is only $19.99! Buy your copy online, and get your registration code in minutes!

RF Toolbox is available for both Macintosh and Windows systems!
