Software/Antenna analysis
Developed for beginners, hobbyists, and field engineers. Includes polar plots, rectangular plots for input impedance and VSWR, tabular data, NEC-Win Synth Light and Necvu 3D. Includes NEC2. The program also offers stepped-diameter corrections, Gain Averaging Test, CAD (.DXF) file input, 2-D and 3-D plots and antenna views, and graphical outputs. Run on older Windows version and is out of support.

Software/Antenna rotor control
his controller uses the Yaesu GS-232 command set to control a Yaesu G-5500 Az-El rotor. The controller was designed to be compatible with the SatPC32 tracking program and should work with any tracking program that supports the Yaesu GS-232 format. This controller has been tested with the Arduino UNO and the Arduino Mega2560.

Добрый день, товарищи любители антенн! 
Завидую вашему абстрактному мышлению, и все-таки попрошу -
прикладывайте хоть какие-нибудь схемы, фото обсуждаемых конструкций.
