Any comparison has to be gain vs elevation angle. In my modeling 80m yagis & dipoles don't have sufficient low angle gain until they are up about 150'. A 2L 80m yagi at 150' models its gain peak as a
A lot depends on what angles you need, from where you are. HFTA's Figure of Merit can be useful here. K6TU.net now offers free online terrain profiling for both US and non-US locations, the latter us
There´s a great difference from K6TU terrain files and files you can made from Google Earth :-) At least to my location 73, Jorge --Mensaje original-- De: TowerTalk [mailto:towertalk-bounces@contesti

In modeling at a possible new location I used Google Earth for one direction (north) and then compared it to K6TU's files...pretty close. And, the graphs produced were also looked pretty similar. By
of course a big thanks to K6TU for a great effort I will need to compare like you Bill Certainly from my location the data is not as acurate 73, Jorge -- 73, Jorge CX6VM/CW5W ________________________
