Possibly a silly question but what type of wire should I use for a buried radial field?
So far I’ve had the following suggestions from several people of varying wisdom!!!
Use antenna wire which can be bought from radio shops (usually copper with a plastic outer)…quite an expensive option, but should work well.
Use 12 gauge bare copper wire…probably the best performing (I believe that this is what they use when they build commercial radio towers) but I think this will be hideously expensive (probably prohibitively so).
Use fairly thick automotive/marine cable…probably the most likely candidate in my mind.
Use the old reel of CAT 6 cable that I have laying around!!!..I’m really not convinced with this idea! This was suggested because it is extremely cheap and I already have a couple of hundred meters of the stuff laying around from a previous computer installation project which is probably never going to be used (and thus probably eventually destined for the dustbin). I currently use this for the radials of my portable setup with some success but I’m not sure how well it would handle being buried for several years!
Use electric fence wire (either galvanised steel or aluminium)…this is by far the cheapest option but I’m not sure how well it will handle being buried under ground. I guess that it’s tough and the aluminium would probably be ok? I suspect that steel wire would just rust. Theoretically I guess they galvanise steel to prevent it from rusting, but I’m still not convinced that it will last very long!
What’s everyone else’s opinion? What have other people used when they’ve buried radials?
Obviously this project means digging up most of my back my garden, so I want to make damn sure that I only have to do it once!!!
