A transmitter has an output of 1000 watts PEP. The coaxial cable, connectors and antenna tuner have a composite loss of 1 dB, and the antenna gain is 10 dBd. What is the Effective Radiated Power (ERP) in watts PEP?
- A10 000
- B9000
- C8000
- D1009
Correct answer: C — 8000. From the official ISED question bank, verified word for word.
Why
Start with the 1000 watts PEP and apply the losses and gains as a net change. The full explanation — and one for every question — is in Pro.
