LENGTH IN METERS = 75 / MEGAHERTZ For example, if I'm listening to VHF civil aircraft frequencies, roughly 118MHz to 136MHz, I'll cut the wires for roughly 120MHz with the formula: 75/120 = 0.625 meters Or, to put that in American, L in feet = 468/MHz. 468/120 = 3.9 feet. This is, of course, the length of the entire dipole. For each leg, you'd use 234/120 = 1.95 feet, or simply divide the 3.9 by 2. To convert the tenths of feet into inches, multiply by 12. .9 X 12 = 10.8 inches. -- Tom Sevart N2UHC Frontenac, KS http://www.geocities.com/n2uhc |
