Mild steel wire for Yagis
I plan to make a 6 element Yagi for FM reception at about 100 MHz. I
would like to use 1/8 diameter mild steel wire for the parasitic elements. I have absolutely no experience with mild steel for antennas, but thought it would be more bird tolerant than the copper wire model I made. I'd sure appreciate hearing from anyone who knows about mild steel for "VHF" antennas. Jerry |

A good sized hardware store will have 1/8" aluminum rod or tube. gb |

I have a coil out in the garage but given that I don't keep a very neat garage I'm just not gonna go out at midnight to get an exact measurement. Harold KD5SAK |
You might try some large mild steel welding rod, like the kind used for
GAS welding. What I have seen is copper plated and easy to solder to. John "Jerry Martes" wrote in message news:2%K_d.13959$hA3.6854@trnddc09...

Brazing rod is a bit more expensive and really sturdy unless you have eagles perching on your antennas. -- Jim Pennino Remove -spam-sux to reply. |
Stainless welding wire, comes on a 500 metre roll.
Or get a length of the 1/4 inch plumbers microbore tube also hard drawn copper wire is quite sturdy on sorter lengths. You just anneal it and stretch till it feels springy, by clamping wire in the vice and wrapping the other end round a stick stretch to your specks by pulling on the stick. |
wouldnt it be cheaper and easier to just go to radio shack and by an FM
yagi i believe they have a 5 or 7ele yagi for a cheap price Jerry Martes wrote: I plan to make a 6 element Yagi for FM reception at about 100 MHz.

Thanks for the good information on steel elements for a 100MHz yagi. I
think I was concerned about something that didnt exist. I thought the fact that the steel was magnetic might effect the elements. I'm comfortable with using this steel wire now. I saw the straight lengths of wire at Home Depot where they sell it for hanging Drop Ceilings. It may not be a rust problem because of the coating on the wire But, the antennas will be in the San Diego Calif. desert anyway, so rust isnt a big problem. Besides, these are gifts so the new owners cal deal with the rust if they want clean *and* cheap. PS I'm building this (actually several) antenna for friends who live far enough away from the city that their radio reception is poor. This "building of antennas" is strictly fun and learning for me. There is no chance of my buying any commercial antenna, even if it costs me more to build one. I did build one with copper elements and it worked very well.
