Isolation of guy wires
"Ralph Mowery" ha scritto nel messaggio
link.net... Has anyone thought of trying to use some of the ferrite beads to isolate the guy wires of a tower for RF so the tower could be shunt fed ? Along the same lines could the beads be used to electrically brake up the wires into non resonate lengths ? The inductance of a piece of wire passing through a ferrite bead would be way too low to produce a discernible choking effect at HF frequencies. 73 Tony I0JX |

Ever heard of a w2du balun? http://w2du.com/r3ch21a.pdf How about passing the wire through 50 #77 beads as recommended by the ARRL Antenna Book? -- 73, Cecil http://www.w5dxp.com |
