I think you use the same UF aerial grouping as we have in the U.K.:
Group A (red), ch. 21 - 37
Group B (yellow), ch. 35 - 53
Group C/D (green), ch. 48 - 68
Group E (brown), ch. 39 - 68
Most installations use a group A, B, or C/D antenna, but group E is specified in a few areas where the channels couldn't be kept all together within one of the other
groups.
Wideband aerials (group W, black) are also widely available.
Just to complete the picture for anyone not familiar with our channels, the UHF band runs 470 - 854 MHz with 8MHz channel spacing.
