[VHFcontesting] A question of altitude

[Fred Lass]

To know for sure you must create a path profile and use YT software to tell you the answer.  In some cases the profile matters as much as a mile away.

YT was written by N6BV and is distributed with the ARRL Antenna Handbook.

While the antenna may be 13' above the road on which the truck is parked, the truck may be 20' from a ledge that drops an additional 20'.  When modeling the antenna would you use the 13' or the 33'?  How close or far from a drop could you be to take this into account?
