Mac, Large metallic objects located outside the minimum OFA elipse can affect NSA. I had (suspected) a problem with semi-trailers parked near the OFA of my (10 meter) site. I was able to observe their effect "real time" on my NSA instrumentation (tracking gen) as they were towed away from the area. -Bob Sykes
_____ From: [email protected] [mailto:[email protected]] On Behalf Of Elliott Mac-FME001 Sent: Thursday, October 13, 2005 10:02 AM To: [email protected] Cc: Zakharia Deanna-EDC015; Lewczak John-ETOP37 Subject: Minimal OATS OFA Question Hello group I have been asked a question about the minimal clearance distance for constructing a 2-story building near our 30m OATS. Using the minimal OFA requirements in ANSI C63.4 / 63.7, I am requiring a minimal 15m separation from the edge of the ground plane behind the receive antenna and recommending 100 feet if possible. Of course, I would like to have the building constructed as far as possible away from the OATS.... Is there anyone out there that has had negative experiences with having buildings or other objects located at the minimal OFA recommendations? Any feedback would be appreciated.
