K7FR ran an experiment in the measurements lab at Washington State 
University, passing 1kW through a PL259/SO239 pair and measuring the 
loss with a calorimeter. He measured 1.8W loss at 30MHz: that's 0.008dB.

At 1750MHz the loss was 39W (0.17dB) and the connector failed. More 
details here:

His conclusion: "Before this experiment I was paranoid about my 
connectors.  Since then I have only been concerned with the quality of 
the assembly and water ingress"
