I have heard that burying your cable will keep RF from coming back in
the shack. From what you say it seems like this is possible but at the
expense of using some of your precious watts to warm the ground.

The effect of the buried cable will be to influence the magnitude and
distibution of the common mode current on the feedline.

Yes, the common mode current flowing on the feedline in the ground will be
mostly converted to heat if the line is sufficiently long. Minimising the
current flowing into the underground section helps system efficiency.

But the measure has been effective in reducing RF levels in the shack.
