I'm not able to locate the Starlink dish on my roof because of tree obstructions. I'd like to locate the dish in my yard where I get an unobstructed view according to the starlink app. I'm wondering if I can splice an additional length of cable to that provided with the Kit and how much additional cable I can add? I see nothing at Starlink.com about adding to the cable provided in the Kit. I don't want to add cable if it's not approved by Starlink.
