Antennas+ is a tool for radio enthusiasts to calculate the dimensions of various antennas and matching systems. The application uses Dynamic Page WYSIWYG technology to provide intuitive pan and zoom interaction for entering the data and viewing the results. An Assistant will guide you step by step in entering the data used in creating an antenna design. The antenna designs are stored as pages within workbooks so that you can save and access your designs at any time. The results are graphically presented with PDF results that can be exported as an email Dropbox file Google Drive file or any other format that is offered by your Android File Provider utility.

The antenna and matching systems available for calculation are as follows(more designs are regularly added):

SUSPENDED ANTENNAS (HF)
- Simple Dipole
- Folded Dipole
- Inverted "V" Dipole
- Off-Centre-Fed Dipole
- Horizontal Loop
- Vertical Quad Loop
- Vertical Delta Loop (Top Apex)
- Vertical Delta Loop (Bottom Apex)

MONOPOLE ANTENNAS
- 1/4 Wave Vertical
- 1/2 Wave Vertical
- 5/8 Wave Vertical
- "J" Pole

DIRECTIONAL ANTENNAS
- 3 Element Beam

DRIVEN ELEMENTS (VHF+)
- Basic Dipole

The antenna frequency can be specified in either gigahertz megahertz or kilohertz.

The calculated measurements can be displayed in Metric Units (kilometers meters centimeters or millimeters) or Imperial Units (miles feet feet-Inches feet-Inches-fractions or inches).

The FREE version is a fully functioning application with exception to the following:
