... I would like to try the DXE NCC-1 too (have one sitting here) to
fight some noise on 80/160m ...
I have a Hi-Z 8-circle for RX, TX antenna is a matched tower ...
The DXE manual says:
----
"The NCC generally works best when both antennas have similar patterns,
polarization, and S/N
ratios. You may have to experiment to find the best antenna, but
successful operation occurs more
often with similar antennas.
Use with Beverage or Other Low Noise Antennas
The NCC-1is probably most useful when used to enhance reception on lower
frequencies. The NCC-1
is often useful even if the station already employs low noise
directional receiving arrays.
A suggested method follows:
Connect one Beverage or other similar low noise receiving antenna to INPUT A
Connect another Beverage or another low noise receiving array to INPUT B
Connect theNCC-1 RECEIVER connector to the receiver's input line.
If you are using a Reversible Beverage, runtwo feedlines back to
theNCC-1 INPUT connections. Then use the NCC-1 to control the
directivity and nulls.
----
Any suggestion on how to use the unit best? Set up another single RX
Element? Use 'the tower'?
Thanks!

What is the best acquisition between Timewave ANC-4 or MFJ-1025?
While all of them will work, the Timewave phase adjustment causes a
huge change in level. It also has less phase range. That is bad,
because you have to go back and forth between the controls more.
The phase should really only change phase, and the level or balance
should really only change the signal levels. The MFJ is much better at
control action than the Timewave, and it has much better IMD
performance. The DXE NCC is, of course, better than the MFJ for
everything. The DXE has much wider phase range and better IM
performance, but you pay for the complexity.
