Follow the steps to effectively complete the form.

1. Click ‘Get Form’ button to obtain the worksheet and open it in the online editor.
2. Begin by entering the repeater callsign in the designated field. This is essential for identifying your specific repeater system.
3. Next, input the repeater output frequency in megahertz (MHz) and the transmitter output power in watts. Ensure accuracy as these details directly impact your ERP calculation.
4. Provide the antenna make and model in the respective field, followed by the antenna gain in decibels (dB) over a half-wave dipole.
5. Enter the length of your feed line in feet. This measurement is crucial in determining the overall loss in your system.
6. Select the type of feed line being used from the options provided. This information will help in calculating the appropriate losses associated with the feed line.
7. Fill in the duplexer make and model, along with the duplexer loss. This data will also contribute to the overall system loss calculation.
8. Proceed to calculate the system gain by following the instructions provided in the worksheet. This includes adding the antennal gain and dividing by 100 as indicated.
9. To calculate the total system loss, enter the feedline loss factor from the designated table and add the duplexer loss.
10. Finally, to calculate the system ERP, subtract the total system loss from the total system gain. This value will be your Effective Radiated Power.
11. Once all calculations are complete, ensure to save your changes, download the form, or print it as needed.
