I’ve always presumed that the ratings were based on 1:1 SWR as there is no 
reasonable way to define it otherwise.   Actual ratings at other loads can be 
inferred on that basis. 

An end fed dipole is MUCH harder to tame than a dipole (or fan dipole) and 
inherently challenging to keep the RF away from places like the shack.
