ERP Calculator

Configuring antenna systems with ERP Calculator is easy. Each antenna system requires a section of coax cable and an antenna. Simply select a coax brand and type from the drop down boxes. Now select the coax cable length.

These figures will be used to determine the coax cable insertion loss for the antenna system. Next select an antenna brand, model, and band of operation. The antenna gain will be used to determine overall antenna system gain, and ERP. The antenna system gain and coax system loss figures will fill in automatically.

Change the coax type, or coax length, or antenna model, or transmit power, or SWR value to see how the changes affect overall antenna system performance. No more guessing if one antenna system performs better than another.

After configuring both antenna systems print up a comparison report to see comparisons of the various antenna gains, coax losses and antenna system setting values.

After you have configured a pair of antenna systems they may be saved for future use eliminating the need to reconfigure the systems if working with the same data in the future. This saves time.

To reload a saved antenna system choose Load System then select from the list of saved systems to automatically repopulate ERP Calculator with all the saved settings.

Edit Antenna data with the Antenna Editor. If you like to homebrew antennas or if the antenna brand or model you wish to work with is not included with ERP Calculator simply add it yourself with the Antenna Editor Dialog. Antenna bands of operation, Gain Figures, and Gain Type may be programmed by the user for calculations with ERP Calculator.
