In a case like that, he's doing about as well as one can do, not
counting changes in pattern. For SWL, a slinky is ok. Not so hot
for transmitting though, being the antenna is almost all loading coil
with no capacitance added at the ends. Kind of like running back
to back ham sticks with no stingers on the ends. :/
It'll work, but there are better designs for short loaded dipoles.
