[CQ-Contest] Terrain and antennas

For the price of the ARRL Antenna Handbook, you will get a most powerful
modeling program - HFTA.  N6BV has perfected it over the years and the
results will give you a pretty clear picture of what to expect from various
antenna heights.  Dean's write up is very easy to follow and you will have
everything you need to do the job except the terrain maps which you can
download at no charge.

When I lost my tower in 2002 as a result of a massive ice storm, I used it.
I had a tower at 90 feet but the model told me that given my terrain, 80
feet was the best compromise given that I use a tribander and a separate 40
meter yagi.

We are in the process of moving from the flat lands of Texas to the
mountains of New Mexico, have to get away from the heat.  I need
some input from you guys that live in the hills and mountains.

Our new location is in a narrow valley at about 7800 feet asl.
Hillsides rise steeply about 800-1000 feet starting about 150
feet from where tower will be located.

I would like some comments from you guys that live in the hills
about is it worth it to go to some super tower height to try and
overcome the terrain or would it be best to just put some simple
40-50 tower and live with the terrain.

If you prefer, reply direct to w5kft at nts-online.net

Thanks

Bryan W5KFT
