That is right--it's a simple and effective antenna. But how in
the heck do you make one work without getting RF into
everything. I used a tuner and 80 meter antenna for years,
working lots of dx, but with the advent of computers, I had so much RFI I had
to go to coaxial antennas. And I still have RFI problems in the shack. 73

Very simple, Tom.
You leave the ATU outside, just below the antenna ( in a pretective cover of
some sort) and have just the coax into the house. This requires some walking
back and forth with band change, which is good for blood circulation etc !
I have done this very succesfully with a 2x10 meter dipole. At one time I tied
the feders together as a T-antenna and worked BY1PK on 80m CW, with some
counterpoises on the ground.
