Between the episodes
Small Victories (2000) and
Redemption: Part 2 (2002), the Beta (Antarctic) stargate is used at the SGC for gate travel, since the original gate ended up at the bottom of the Pacific Ocean in "Small Victories" and later fell into the possession of the Russians until its return to the SGC in "Redemption Pt 2". In
Solitudes (1998) (the first episode to feature the Beta gate), the point of origin symbol (an octagon with a line below it) is different from the point of origin symbol of the original gate (pyramid and circle); however, in various episodes that featured the Beta gate in use, the point of origin symbol mysteriously changes to the symbol from the original gate.
