You are right buy I was lazy. I'll need to apply separately for another antenna and I can fix that then. Dick Sent from my iPhone _______________________________________________ _____________________
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
Remember too, if you line up with any of the runways the criteria is different for runway clear zones. Years ago "they" built a new subdivision right across the highway from the S end of 18/38. The N
There's a 20-foot threshold, so at 7 meters the tool must have started looking at the other numbers. I think the main difficulty is that the ground level at my site is 251 feet and the ground level a
Ah, it never occurred to me that your ground level was that much different from the NAS. Yes indeed, unless you want a negative tower height you'll need to move some paper. On the other hand, unless
Do you measure from the airport property line or the runway? _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contestin
I didn't measure a distance, I typed in the lat/long of the tower base and TOWAIR provided the distance to the (presumably nearest) runway from its knowledge of the airport. Dick --Original Message--
You measure from the airport reference point (ARP) which is published for each airport. It's the lat/long of the considered center of the airport. Call the airport, and ask them for their ARP. Van Li

Hi Folks! Here are a couple of useful references to determine the Airport Reference Point and to calculate the distance from it. I first determined the airport identifier for the airport, if I don't
When I checked Towair calculated the airport from the end of the runway closest to me. I looked up my lat/lon on google earth, plugged that into Towair and it gave me the distance from my qth to the
If you are off the end of a runway it's the distance to the threshold of that runway and they use a different (more stringent) height criteria for that. "I believe" Tower Air only figures the ARP. 73
I'm surprised as it didn't do that for me. Again, I only received one here. _______________________________________________ _______________________________________________ TowerTalk mailing list Towe
I use to live north of the air station by Deception Pass. I could swear they were using my roof as a bombing target at 500ft AGL. Lived there for about 10 years and never did get use to it at 2am. No
I asked this question because I am off the end of a runway. Using the TWAIR I am about 1000 feet farther away than when I use a manual calculation from the end of the runway. Well for me either way,
Thanks to whoever started this. I put in my lat/long and found I was near a grass field I did not know about and my tower project will be about 24 feet too high without registration. The tower was al
I fast fingered and deleted the web site for TOWAIR. Would some please post again. Thanks KD8DEG Tom Thanks to whoever started this. I put in my lat/long and found I was near a grass field I did not
