About RF ToolBox
An antenna design and electronics/electrical tool package. It takes you step by step through the design of the following types of antennas:

- 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
- Resistor Color Code
- db Calculations
- Low and High Pass Butterworth and Chebyshev Filter Design

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.

What’s New in this Version
- Added Resistor Color Code Calculator
- Added Universal Binary support
