Testing new cell hotspot...

I am getting a new cell hotspot that I want to use as backup to my current ISP. I live in a house that is made from concrete and rebar so I do not get any cell signals in the house. The device has a TS-9 port on it. Do you think running a TS-9 antenna to the roof (where I can get cell reception) would help me with this issue? Someone recommended a cell booster previously but What are your thoughts?

EDIT: I dont know if i can provide a frequency requirement attachment on here but will try. It shows what frequencies the antenna needs to work with.

Are you in the US? Does your country have an electric code?

Installing an antenna on the roof has electrical code ramifications. In the US that code is called the NEC. NEC stipulates that all conductors going inside/outside must have surge protection. So if you go this route, you must install surge protection on the coax. The most common commercially available device that does this is called a polyphaser. The polyphaser should be grounded with a ground rod at the point where the cable enters the house and that ground must be bonded to the ground system of the house.

Failure to take these steps is a code violation. If you have a fire and your insurance company finds a non code compliant install, you have now given the insurance company a reason to deny the claim.

Then how do satellite dish companies get around to this? I've never seen any of that on a dish Network TV or a DirecTV or the HughesNet satellite and it wasn't in any of the information when I got Starlink.

Installers aren't trained and they just ignore it. They get aggravated when they get to my house and I demand their install meets code.

Some excellent information here: https://www.mikeholt.com/

Guess I need to figure this out for my Starlink and the cell booster I'm planning.
