6 inch x 8 inch USA AMERICAN Antenna Flag for Motorcycles, cars, trucks, Jeeps.  Attaches to antenna at base of flag, just secure with small zip tie that is included with your flag.  Antenna opening is 3/4 inches flat, so with both sides would be 1 1/2 inches, and 9 1/2  inches tall.  Flag is sewn on edges to help keep from fraying.   Made in USA by me.
