Saturn square Uranus (orb 1.3°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Saturn in Capricorn in House 7 brings discipline, constraint, endurance, and mastery into House 7 (relationship, confrontation, and the mirror of others), with Capricorn style (structure, ambition, responsibility, and long construction); Uranus in Aries in House 11 brings disruption, independence, and change into House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects), with Aries style (initiative, speed, confrontation, and direct action).
Concrete friction: this aspect puts Saturn (discipline, constraint, endurance, and mastery) and Uranus (disruption, independence, and change) into repeated friction: one can interrupt, inhibit, or provoke the other in concrete situations. House 7 (relationship, confrontation, and the mirror of others) is in friction with House 11 (networks, audience, groups, ideas, ideologies, political beliefs, and collective projects); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
