I went to the Fracarro website not yours.
The following antennas fail
Al6HD, Al18HD, Al23HD, Al30HD, Hills DL3, DL4, CA16GL, Fracarro 4E2, 4E3, 4DF (not Au ch6 but Au ch 2) Remove them from sale.There is now no locations which require any channel below channel 6 provided they have a digital receiver or set top box.
Fracarro 6E5 - 6E12, 11D5 - 11E12 single channel antennas are only suitable for monitoring individual transmitters,and the worst case large MATV systems which would be rare.
When I go to your website I wish to make the following comments which applies after the digital restack.
Your entire Log periodic range becomes redundant.
The broadband band 3 Yagi-Uda antennas are fine for group A, except for band 3 UHF combination which will not be required. Sigma combo is one of those.
The band 3 phased array you sell is not Fracarro, but Hills.
The Laceys catalogue shows the following Fracarro products which do not appear in the Fracarro international catalogue
10 GAMMA/R Au ch. 20-31 11dB gain 24dB f/b ratio.
10 DELTA Au ch. 24-36 11dB gain 20dB f/b ratio.
10 DELTA/R Au ch. 24-36 11dB gain 24dB f/b ratio.
10/3539/R Au ch. 28-42 11dB gain 24dB f/b ratio.
10/4046/R Au ch. 34-49 11dB gain 24dB f/b ratio.
10/4753/R Au ch. 40-57 11dB gain 24dB f/b ratio.
10/5461/R Au ch. 46-67 11dB gain 24dB f/b ratio.
10/6269/R Au ch. 55-75 11dB gain 24dB f/b ratio.
The only ones on the Fracarro catalogue narrower than Au channel 20 - 75
E21 - E26 470 - 518 MHz Not used for TV in Australia
E26 - E34 518 - 582 MHz = AU 27 - 35
E34 - E46 582 - 678 MHz = AU 36 - 48
E46 - E69 678 - 862 MHz Will not be used for TV in Australia after the restack
are shown in the Fracarro international catalogue.
None of the above frequency ranges match individual UHF groups or even pairs of groups.
Their new range using circular elements are a worry here because Fracarro do not quote the vertical and horizontal beam width. These antennas may have trouble rejecting signals of the other polarisation on the same channels.
No amplifier should now amplify any frequency below 174 MHz, outside the range 526 - 820 MHz which will have to change the UHF top limit to 694 MHz when the the restack occurs.
A Fracarro channel cut antenna provides substantial improvements in gain,
front to back ratio and beamwidth, providing results where other antennas fail."

"the hills combination band 3/4 antennas you mention might seem mechanically interesting but their performance is awful - is this a reference antenna for anything?"
Lastly do not rubbish any competitor unless you can backup your claim. What characteristic of their performance is awful and what is the comparison reading?
As for reference antennas if you go to the CAI's website the LPAs were the worst performers. The UK has no band 3 TV and considering that 50 % of the Australian population require band 3 makes your claim largely irrelevant. An antenna is not a reference antenna unless the frequency range and polarisation matches the transmitter being used.
Fracarro is not the only manufacturer making wideband UHF antennas and none should be used here. This may become increasingly important as the broadcasters try and put more programs into the existing digital TV channels.
