Starlink on a sloped roof

[dr_t]

I asked my builder to install my Starlink dish on the roof of my barn, which is the highest point on my property. Since we get lightning storms sufficiently regularly, I asked him to also install a lightning rod taller than Starlink near the Starlink dish to protect it from lightning. The roof is a typical sloped roof - i.e. a ridge in the middle at the tallest point, then two downward sloping surfaces, one on each side of the ridge. The builder put up two lightning rods, one at each end of the ridge, and connected them with a copper strip running along the top of the ridge, the whole length of it. Now there aren't supposed to be any antennas at least 6ft away from the lightning rods and the connecting strip. Which means there is nowhere at the top of the roof to install Starlink. I.e. the antenna can now only be installed on the sloped part of the roof, at least 6ft away from the top of the roof.

Is this even workable? Will the dish see enough of the sky?

The barn roof is a corrugated iron roof, and the builder told me the best mount is the flashing mount, so I bought that (previously, I had bought a pole mounting kit and asked him to install the dish on  top of a J mount secured with several brackets).

To make matters worse, we get a lot of high winds here. Occasionally hurricane force. So if we install a tall pole mounted on the roof and elevating the Starlink dish high enough to be able to peer over the ridge of the roof, it's going to be very difficult to mount it securely enough not to be blown away when the wind blows.

Is a regular flashing mount / pivot mount going to work?

Thank you.

Unless you have a lot of tall trees near your barn, I'd be more concerned about the possibility of magnetic interference from the lightning rods and the copper strip. There's no way to really guess whether that's going to be a factor in your Starlink reception without trying it... at least, as far as I know.

I'd take a day or two and put the antenna up on the roof -- without permanently mounting it -- and see how things go. Pick a time when you won't have those high winds, for sure. Give yourself some times to test things in multiple locations and see what happens. 

Once you find the optimal location, then use the flashing or pivot mount to permanently mount your dishy. 

Suggestion: if you are in the northern hemisphere, try putting your dishy on the more northerly slope of the barn roof. It is going to face north-ish once it is up and running.
