In a very difficult area with not clear line of sight to a relatively low power transmitter (Dionysus) at a distance of 15 KM and a 40 db mast amplifier, it performed at 95-100%. Be careful with the elements, they can't handle rough treatment until you install it. Sturdy clamp. It's worth the money.

Entered a multi-storey building with visual contact of the local center, but it looks at a center in another area about 30° diagonally, which is 75km away, and brings signal and quality of 95+% from both centers...
Of course, there is a central amplifier - splitter

Installation in Agia Paraskevi with line of sight to Ymittos antennas feeds 3 televisions with a triple splitter flawlessly
