For best results, KVH recommends 14ft separation between Starlink antenna and satellite TV receiving antenna.  These recommendations apply to all satellite tv receiver antennas from Intellian and KVH when installed near a Starlink antenna.

"When choosing the mounting location for a new Starlink antenna, be sure to consider the distance from other satellite antenna systems, such as a TracVision® antenna, to avoid potential RF interference. As specified in the Starlink Wedge Mount Kit manual, other satellite antennas should be located at least 14 feet (4 m) away from the Starlink antenna. If the antennas are mounted too close to each other, Starlink transmissions may interfere with the existing TracVision antenna’s ability to receive satellite TV signals due to the proximity of their frequency ranges. Ideally, the Starlink antenna should also be mounted in a location that ensures the TracVision antenna is outside its 140° look angle."
