CREATE TABLE table_1945 ("Property" TEXT, "K-band" TEXT, "Ka-band" TEXT, "Q-band" TEXT, "V-band" TEXT, "W-band" TEXT)

When 2 is the ka-band how many properties are there?
SELECT COUNT("Property") FROM table_1945 WHERE "Ka-band" = '2'
SELECT COUNT("Property") FROM "table_1945" WHERE "Ka-band" = '2'
