That said, can someone remind me of the formula for calculating the length of a full-wave antenna wire if the frequency is known (think whip and a frequency of 160.890 mhz). Your ant would be 2.9088196904717508856983031885139. So about 2 15/16 or so inches. I wouldn't recamend a dipole config. LOL!!! Are you sure about that length? A dipole at 144 MHz is much, much larger than that, so something at 160 MHz or so isn't going to be that much smaller. dxAce Michigan USA I don't know what the logistics of VHF and above would be but the math says it's so. I'll have to refer to my ARRL handbook. I'm a HF guy and the math works for that spectrum. B.H. At 160 MHz the halfwave length would be 2.9 feet. |
