This video explains the typical installation and grounding of off-air antennas including UHF yagi reflector antennas, FM antennas and dish antennas. Factors that should be taken into account when installing these antennas include antenna alignment, wind, surrounding mountains, elevation and placement, which are all mentioned in this video.

@FloryJohann The should've installed them on the that wall next to them.

@FloryJohann With strong winds satellites and antennas become loose from the base and if water accumulate on a a flat roof then it will come down and cause damage even if yo0u apply silicone.

You are right, those bases are weak.
Antennas need to be higher.
But the distance between the antennas is ok. About 2 feet would be the limit for those frequencies.

At leased around here they use silicon/rubber based stuff before they screw the base down on a shingled roof.
On a flat roof like this they would seal everything with roofing material after install.

I would mount those antennas much farther away than 6 feet from each other, and certainly a quite a bit higher. Those bases look incredibly flimsy, I wouldn't expect those to withstand any high winds.

Screwing into a flat surface on the roof??? Nice Job Fellas. you do that in NYC and get ready to pay for a new roof and who knows what else. Usually you put a rubber mat and a metla base held by 4-5 cynder blocksand then you mount your equipment on that base
