One thing I am surprised no one has mentioned is that the
DXE preamp requires the user to tune a front end filter to
a particular frequency range. This makes it into a 1 band
solution. A receive 4 square might be useful on more than
one band and it is also useful to be able to receive WWV on
2.5 MHz for testing purposes. Another disadvantage of the
DXE front end filter is that component tolerances will result
in phase differences between units that will degrade the
pattern.
The Hi Z preamp is truly broadbanded and is checked at the
factory for phase matching.
