[Fourlanders] FW: Antenna Analysis

[wa4kxy at bellsouth.net]

Hello everyone.  Does anyone have a copy of the Twentieth or newer edition of the ARRL antenna book that Sherman can borrow?  In particular, he needs the CD that came with it.  Sherman is trying to do some analysis of our 6 meter antennas and their takeoff angle.  If you have one and can bring it to the lunch after the hamfest I can get it from you then.  Thanks.

I did some research on the antenna analysis with terrain that I saw and 
the program that is used is called High Frequency Terrain Analysis 
(HFTA). It is available in the ARRL Antenna Handbook. I have an old 
handbook with a similar program but it is on a floppy and I do not have 
any computers that can read a floppy disk any more! 

But this program will take US government terrain data and determine how 
the takeoff angle changes for a yagi antenna. I'm not sure if it works 
at 50 MHz. 

Do you have the 20th edition antenna book with the CD rom?
