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 Lat/Lon)  
and "HFTA" itself is easy to use. The PITA is using Microdem to generate the 
terrain files that are needed for import into HFTA to model your own 
surrounding terrain.   

If you are happy modeling your antennas on flat ground you can start using HFTA 
in about 10 minutes.

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  among the earlier designs for hikers and don't have as 
many fancy features as the newer units so the hikers are unloading them. I 
find them ideal for my simple minded boating because they give you just what 
you need to get from here to there and don't complicate it with a  lot of 
stuff I'm nor interested in, but they do also give you lat and long, so you 
can just take it to the base of the tower and read degrees, minutes and 
seconds, which should be close enough and can easily be converted in decimal 
equivalents that can be entered into the HFTA program.

I agree that it is a PITA to use HFTA but it does give a lot of good info 
for those who persist. Even if you have already committed to your 
installation it's interesting to see what kind of performance you might 
expect. Or, if your looking for a place to buy or build it's a good 
evaluation tool and you'll learn lots about the ups and downs of the 
neighborhood within a radius of a couple of miles.
