Have personally asked Kathrein and Donqui about this and both of them replied that their antennas require no grounding.
Stop wasting the cable, guys.
How exactly do you ground an antenna? Is there a specific point or you connect it inbetween a nut and a locknut?Grounding as in connecting a wire from an antenna to earth or a building AC panel ground has no RF performance impact to any VHF or UHF antenna I know of. However, it can have a huge impact on human safety from electrocution when the ground potential of the antenna is radically different than the rest of the equipment its connected to. Grounding can also can have a huge impact on what happens when lightning strikes the antenna or something nearby.
In the US, the National Electrical Code REQUIRES you to ground your antenna to the same potential of the building AC ground potential and by very specific means. So it would be incorrect and somewhat reckless to tell everyone not to ground their antennas.
