- WELCOME TO THE K2TV ANTENNA CALCULATOR
- copr 1988, Robert W. Myers
-
- This program will calculate the length of a quarter wave
- vertical, five eighths wave vertical, half wave dipole, or a
- multiband windom antenna and give the results in feet and inches.
- To start the program type <antenna> and push the <enter> key on
- your keyboard. An opening screen will come up and after reading
- the screen push the <enter> key again, a menu will come up asking
- which type of antenna you would like to have measurements for and
- what is the desired frequency. It is important to enter the
- frequency in MegaHertz; for instance if you wanted to calculate
- the frequency of a windom antenna for the middle of the forty
- meter novice band, select <D> and enter <7.125> and press
- <enter>. You will get the results in feet and inches with the
- offset feed point also calculated. Be careful to make all
- entries in decimal numbers, for example: 7.250, 144.5, 28.475
- etc. If you make any calculations for antennas below one
- MegaHertz, enter a zero before the decimal point, for example:
- 0.880, 0.375, 0.640, etc.
-
- I have tried the program at various frequencies and it seems
- to be accurate for most Amateur Radio bands up to six meters.
- The calculations are rounded off to the nearest inch which should
- provide an accuracy that is good enough for the construction of
- a practical Amateur Radio antenna installation. The formulas used
- for the calculations in this program are the standard antenna
- formulas that can be found in any source on antennas. Further
- information about the antennas calculated in this program may be
- found in the ARRL "Antenna Handbook" or the ARRL "Amateur Radio
- Handbook" published by The American Radio Relay League, 225 Main
- Street, Newington, CT 06111.
-
- The intent of this program was two fold, first to give me a
- chance to practice my Pascal programming and second to provide a
- simple program for those that may be interested in designing
- antennas, especially when trying to play "what if" in trying to
- find an antenna to fit a given space. You may freely copy and
- give away this program to others as long as the program is
- accompanied by this ANTENNA.DOC file and I would hope that it may
- be of use to the Ham Radio community.
-
- There is no Warranty for this program or its use, implied or
- otherwise. You use it at your own risk and the author cannot be
- held liable for any damages from its use or problems that may
- come about from its use or misuse. Please feel free to contact
- me with any suggestions or comments about this program, so that I
- may make future revisions.
