How can I increase the range of my Starlink? (AUS)

Hello all. I have Starlink on the roof of my house. I have a shed about 30meters away down the back. For whatever reason, my phone/ipad can connect to the Starlink down there no problems. However, I have a TV down there that can detect the wifi is there, but it’s not enough to open or play anything. Is there a way I can increase the range to be able to watch my tv in the shed? Our old broadband wifi worked fine, but since changing over to Starlink it’s no good.

Thanks
