Newer versions of the DW32 and DA43 amplifiers have in-built 4g filtering. Please note that they no longer appear to amplify frequencies above RF51 meaning that any closed circuit MATV systems where you have frequencies in use above RF51 will skew.

For this reason please identify any systems that have integrated/modulated channels above RF51 so that we can re-modulate to a lower frequency, or find a more suitable broadband amplifier for the specific venue.

In short, The Clear Cut-Off: Free-to-air UHF (Ultra High Frequency) television in Australia now operates strictly within the frequency range of 520 MHz to 694 MHz, covering RF channels 28 through 51 so amplifiers and in-house mapping of frequencies must fall between these frequencies if the newer amplifiers are to be used.

NB this applies to Aquis park which has frequencies above RF51. The newer amplifier cannot be used on this site.
