Yes. you connect your antenna wire to one of the test points in the RF 
deck.. I suspect it is at the grid of the first mixer, after the RF 
amplifier stage(s). You may want to ground the normal antenna input jack, 
or pull the first RF amp tube. You may also want some kind of low pass 
filter in the antenna signal path to avoid broadcast band interference.

The trick was published in Hollow State news, I believe.
