thanks for the input good fellows!
I'm obviously just playing around here. I have looked round on the net and it's a cobweb antenna I was headed for. I had the idea explained to me, but until I saw it, I had NO IDEA! now it a tad clearer. http://www.g3tpw.co.uk/ here is the website I found. clear as mud now... thanks again. |

First, the design you are looking is NOT a loop (nor loops). The design you are looking is NOT a beam. The design you are looking is NOT directional. Aside from that, it has been around for a while, and satisfies many. You may be one who would be happy with it, but that is obscure until you tell us what you want to achieve without trying to shoe-horn in presumed solutions. The simple explanation for the design you have linked to is that it is a "Fan Dipole." The fan is found in the common feed point (at the left) supporting paired wires for each band spreading (fanning) out. What makes it unusual is that it is wrapped into a box-like footprint (without the ends meeting, look closely at the photo). The wrapping also changes the usual dipole radiation characteristic from dipolar (radiating in two major lobes) to nonpolar (radiating in all directions). Do you have a call sign? 73's Richard Clark, KB7QHC |

Do you have a call sign?
no, no call sign, I have just been given a shortwave radio Realistic DX-300 Shortwave Radio Receiver. I was told I could just hang a good length of wire out in the tree and it will work. It does but thought I would have a bit of a go at improving things. I read a lot on the ham radio news groups, but you can get bitten when you ask a question, so thought would try here. I quite like listening to ham types, and the techno talk, not too keen on the 5/9 next please bust busy contacts, but when people have real conversations about making stuff its good listening. .. thanks anyhow. |
