sometimes three or more signals on the same frequency just by changing directions. Do
your testing at night when the low bands are open to see the greatest performance.
Also, vertically polarized signals will exhibit both good front-to-back as well as front-to-
side ratios. Often local interference sources are vertically polarized and can be attenuated
by pointing the antenna away from the source.
Ionospheric conditions can impact the apparent directivity when listening to sky wave
signals. Expect degraded directivity (less front-to-back and front-to-side ratio) during
active and stormy geomagnetic field conditions.
If conducted shack noise is a problem, try running a short wire from your receiver to
either the shield of the RCA cable at the controller, the RG-6 cable connector, or the (-)
side of the DC power connector.
