To Calculate length for Inverted Vee.
For Vee slope (top of mast or tower to anchor) use;
5% for 45 degrees.
4% for 40 degrees.
3% for 30 degrees.
2% for 20 degrees.

Division Factor:
(*For 1/2 wave use; 468 for Feet or 143 for Meters*)
(*For 1/4 Wave use; 234 for Feet or 71.5 for Meters*)

Enter The Frequency For The Dipole / Vee Antenna Calculation
Best tuning frequencies for most phone bands, and 30 meter CW are:

160M = 1.900MHz 80-75M = 3.900MHz 60M = 5.3570MHz

40M = 7.215MHz 30M = 10.125MHz 20M = 14.250MHz

17M = 18.135MHz 15M = 21.300MHz 12M = 24.960MHz

10M = 28.500MHz 6M = 52.000MHz 2M = 146.000MHz

1.25M = 223.000MHz 70CM = 435.000MHz
