Coupling into my power upstairs is a bit of a problem sometimes though.
Pirating power is something I've heard that happens, but I looked it up, and couldn't find an actual cited example of someone doing it via induction.
Plenty of people doing it via extension cords and device tampering though.
I haven't worked with my end-fed on 40m for a couple of years. We've recently all had our crappy old aluminium-cored BT lines replaced with shiny new fibre though, so this time I am unlikely to lift the coveted Worked All DSLAMs trophy ;-)
