[Elecraft] Input vs. output power question

[Bekir Kemal Ataman]

I intend to join the IARU HF contest in the QRP category (i.e. 5 watts output).

I have got a RG58 going to my inverted V antenna. The coax is about 45
meters in length (roughly 135 feet).

How much power should I request from my K2 to get 5 watts output from the
antenna?

73!
