Narrative:

Prior to a local flight at 1f7 to practice touch and goes; no notams about antennas or obstructions were noted when I checked during preflight. While in flight and on go-around on runway 13; I saw an antenna whiz by that has been mounted on to what appears to be the maintenance hangar; with no NOTAM added for the hazardous obstruction. Fortunately I am familiar with this airport and was on centerline for the go-around; but less familiar pilots with any left-drift on runway 13 or right drift on runway 31 will have a considerably reduced margin of safety for obstruction avoidance. I'm not sure why the new tower isn't notamed; it certainly seems hazardous enough to warrant consideration for the flying public.
