*Subject*: [amsat-bb] Phasing Cables Calculations*From*: "John Germanos" <wb9pnu@xxxxxxxxxxx>*Date*: Mon, 26 Jun 2006 17:20:00 -0500

I am stcking four 2m yagi's in "H" pattern. I am trying to calculate the lenght of the four cables to the 4-way power divider. I think it goes like: 11802.8/freq.Mhz, then divide by two for half wavelength, then multiply by velocity factor of cable (for Andrews FSJ4-50B = .81). Using 144.140mhz, I come up with 33.163 inches of 1/2" heliax per 1/2 wavelength. Then I multiply by 3 for convenient cable length, 99.49 inches. Is this the correct way to calculate the cable lengths? All help appreciated. 73 John WB9PNU ---- Sent via amsat-bb@amsat.org. Opinions expressed are those of the author. Not an AMSAT member?
