the other day I watched an installer put a new TV antenna on top of a block of units in Sydney - from the roof top there is a line of sight to the transmitter towers 11 kms away.
He removed the old antenna that had been there for 10 years or so and replaced it with an identical looking one - a "combination" analogue /digital type with elements all in one plane - like this one:

In 18 months time, analogue TV will be switched off in Sydney - whence all such large antennas will become unsaleable.
Something like this one seems more logical as it is a fraction the size and gives far more gain and a better F/B ratio.

Surely the owners of the block would be well advised to go for an antenna like the above.
