Topband: Question on active vertical spacing

[Rob Atkinson]

My rx antennas are around 40 to 50 feet separated.  I get good peaks
and nulls on 160 and the top of the AM broadcast band.   80 m. doesn't
work as well.  But 160 is where you really want it to work.  That's
where noise is a big problem.  Use a groundwave broadcast station on
1400 or higher to test your setup and practice using it.  It helps if
you have some kind of receiver with a panadapter.  As you rotate
through the phasing you can see the broadcast carriers move up and
down.  Using phase and balance between the two antennas, you should be
able to take a pretty strong carrier and put it into the noise.
