Where can the software be obtained? Is it downloadable or do you have to by the ARRL antenna book to get a copy? I'm in the middle of installing my tower and I'd like to run some numbers. Thanks Rich
Need to get a copy of the ARRL antenna book. I'd say it would be easy for someone to run it for you, but the real value comes from having the terrain data, which is a somewhat complex process and loc
It's enough work that I suspect that most folks who have done it would not be willing to do it for you. Besides -- you learn a lot in the process. To clarify about GETTING the software -- it comes on
I wanted to use HFTA with the terrain data but could never find anyone who knew how to make it work. I just went to the PVRC website and searched for WebEx but it came up with nothing. Do any instruc
Jim, if you did build a simplifiied way to enter the exact location of the antenna to import into HFTA you would be a hero to the masses because Microdem is a true PITA! Note that unless the site is
I think that may be a bit of an exaggeration, especially since as others have pointed out here you're not really certain where "ground" is anyway ... certainly not within inches and probably not with
RE your exact tower location - Small handheld hikers GPS units that give Lat. and Long. can be had on eBay for cheap. I found several Magellan Blazer 12 units in the $25-$50 price range . They were a
Google Earth is simpler, it's free to everyone, and at my QTH in the boondocks of southern Arizona it will pinpoint my tower to the nearest second. Dave AB7E _________________________________________
Yes, and once your tower is equipped with aluminum and Google Earth has updated their photography, you'll be able see the antenna! Mine is visible just NE of my house. Get my qth from qrz, then tell
I had a minute to do some poking and found this link to it on the NCCC website. I don't think it's in the "members only" section. This will play in Windoze Media Player. http://nccc.cc/misc/HFTA.wmv
Well.. I have a set of pre-SRTM CDs with DEMS on 3arcsecond increments (about 90 meters) in 1x1 degree squares. SRTM is about 3 times better than that if you get the DTED2 files. It's pretty easy to
Yes, the handheld GPS will work just fine...... AND, you can use Google earth to find the exact location of your tower for free (place the curser over your tower or proposed locations and read the La

I think that it would be pointless running the program on flat ground. No-one has ever been able to help me run the program with real data even though they offered to try, so I just had to guess when
...but I suppose the question becomes how much MORE dx could you be working with a totally optimized situation? If you are comfortable never knowing the difference, lucky you. Because the alternative
3C0E 17m ssb first call. last night and 3C0E on 20m cw so I am happy. I often get reports that I am the loudest on the band, so no complaints here. I really didn't have the time or inclination to fig
BTW - no sarcasm was intended there. I really would like to think that at some point someone - somewhere - will make a program that is easier out of the box. But in the meantime, here are some operat
I supplied some HFTA plots to the N5ZC, the originator of this thread last night. If anyone else wants JUST the radial elevation profiles but doesn't want the hassle of learning Microdem and extracti
I wonder how many tribanders are out there at 40-50 feet either strapped to the side of, or on side gates, on 75+ foot towers as a result of HFTA, or were put there as a result of observed need befor
Yes, MicroDEM is a PITA, but there is a wealth of information available on how to use it and HFTA. The biggest PITA, actually, is that the USGS contractor responsible for the seamless database and it
