MS Excel worksheets:

YagiQ.zip   new!

Tool for antenna Q factor and Figure Of Merit calculation as additional post procesing software for 4nec2, Eznec and similar antenna simulation programs. These figures are calculated by using and combining calculated, idealized, performances of antenna (Gain, Input Impedance, SWR and Antenna Noise Temperature) that are simulated in antenna software. 

TubeCalc 3.1

Input (grid or cathode) and output (plate) tube resistances calculation according to its electrical characteristics, frequency, mechanical dimensions and working conditions.

 

HeliCoil 3.1

Inductance calculation  for single layer, air-wounded coils and helixes up to about 800 MHz. Inductance calculations accuracy is around 1%. Also, coils with maximum Q for given inductance, resonant RF chokes,  PI and T resistive attenuators calculations are provided. Skin effects, radiation losses and other minor side effects are not accounted in maksimum Q factor coils calculations. Program assumes using copper (Cu) enameled or silver (Ag) plated wire. Program is writen bilingual in English and Serbian.

 

 

MS DOS programs:

HeliCoil

Inductance calculation program for air-wounded coils and helixes up to about 800 MHz. Inductance calculations accuracy is around 2%. Skin effects, radiation losses and other minor side effects are not accounted in Q factor calculations. Program assumes using copper (Cu) enameled or silver plated wire.

RF Filters

Program for calculations of HP, LP and BP filters at VHF and UHF frequencies up to about 800 MHz.

Parabolic

This program calculates geometry, gain, losses, efficiency, directivity pattern and other parameters of primary fed and offset parabolic antennas.

Geosat

Calculate Az-El position of geostationary satellites at specific location and carrier to noise ratio of received SAT TV signal.

Networks

Calculate impedance matching networks.

Log Periodic

Program calculates dimensions of log-periodic antennas.

MatchNet 2.1

This program calculates impedance matching for tube and solid-state PA, LNA, antenna match-box, interstage impedance matching and all other impedance matching in electronic and telecommunication.

Warning: Using of this program assumes knowledge and experience in constructions and projects. Program will always give some calculation results, but how it will work in practice, and even whether will work at all, depends completely on user of the program, and so responsibility is always on him.
