 ```This sure suggests a computational error in the TOWAIR routine - like when you do a model in HFTA and a 1-meter change in antenna height produces a big change in pattern. I think the first thing I'd do is a manual computation based on a topo map. Measure the distance from the nearest border of the airport (for a conservative calculation), your site's altitude, and apply the algorithm given in the FCC reg. 73, Pete N4ZR The World Contest Station Database, updated daily at www.conteststations.com The Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com On 4/2/2010 6:26 PM, Dick Dievendorff wrote: > At 6 meters of tower height, I don't need to register.
