CREATE TABLE table_1941 ("Property" TEXT, "K-band" TEXT, "Ka-band" TEXT, "Q-band" TEXT, "V-band" TEXT, "W-band" TEXT)

When 4 is the v-band what is the overall amount of ka-bands?
SELECT COUNT("Ka-band") FROM table_1941 WHERE "V-band" = '4'
SELECT COUNT("Ka-band") FROM "table_1941" WHERE "V-band" = '4'
