RR DB for Ventura county Retail has 2 listings for Costco Oxnrad:
154.490 WQMZ420 PL 67.0 per FCC records which I verified a few years ago from home with previous antenna.
154.600 No License CSQ of which I have no knowledge.
151.625 is listed as Red Dot under Common Business
Has 151.625 replaced either or both 154.490/154.600 or is it in addition?
