thanks Booty, I only started the thread, it's the people who replied that really made the thread :)


I did consider the open coil approach, but I really don't have the tools to fabricate something like that, so it was quickly dismissed. I suppose it could be quite easily done though if you could bend some copper pipe into a circle. My tools are limited to a drill, a saw and a screwdriver really, lol. I spent a few hours on it today and I'm nearly ready for testing. Its all a bit Heath Robbinson at the moment, this is the first time I've made a verticle, apart from a 1/4 wave about 15 years ago. I've made a couple of quads before, I've wanted to make a Yagi but the main problem is obtaining aluminium tubing, which has been the same with this project. I actually have somewhere I can buy it from that is only 5 minutes drive away from my house, but the prices they charge just doesn't make it viable to use, it would be cheaper just to buy a ready built antenna than to buy the parts. I suppose it's because the antenna manufactures buy in such volumes that they get a better price than me just wanting to buy the odd length.


I looked around for some aluminium plate to suport the ground planes and I couldn't find any anywhere, unless I wanted to buy a 6' x 4' sheet of it, even if I did that I couldn't cut it down to the size I need so I ended up using some pine skirting board I had in my shed to support the ground plane with, hehe. It's made the antenna a bit heavyer than I wanted, but it should be ok I hope. One added benefit from using the wood is that now I don't need to isolate the antenna from the mast at all. The 4 ground planes are completely isolated from the mast anyway. The antenna isn't going to be a permanent installation, it's really a replacement for my A99 that I would put up when I go /p on top of a hill, so I've made the ground planes so that they will fold upwards while being transported. I'll try and get some pics on here soon seeing as I'm nearly finished now and report back with how it works, providing it does actually work, lol.
