Описание: Antenna99 is designed for easy calculation of Antenna Element diamentions in the HF and VHF range. This Software is very simple to use with input of Frequency (MHz) for which the Antenna is to be designed and Number of Element for the Antenna. The calculations are based on the data taken from the ARRL -Antenna Hand Book .The Frequency and the Number of Elements are entered in the appropriate input boxes and the selection button for the type of Antenna is clicked, the required data appears on the Window. The actual length of the Antenna is dependent on the location, distance from the ground or any fixed structures, size of the Element matrial etc. The length of the Elements obtained by calculation is approximate and the actual length is obtained by pruning the Elements to minimum possible SWR.
