SGC-230 wire endfed or traped endfed

I do not have a ground system in place. I can put some earth rods in and some surface wire but I have no way of putting any wire into the soil itself. So I am a bit limited. I have a 150ft of flexweave wire that is uv plastic coated to play with. I think I have three choices to chose from at the moment. I can use the SGC-230 with an inverted L. I can use the SGC-230 with an inverted L with homebrew traps built in. I can use an inverted L with homebrew traps built in but without the SGC-230. What would be the best choice and why? Many thanks I am going to give it a WAG and suggest you would be better off without the traps. Can the tuner be mounted in the weather? If so, put it as close to the wire as you can and as high as possible. If not, does if feed twin-lead? If so, could you make a 150 foot dipole and feed it with twin-lead to the tuner? I would like that idea best. Even 300 ohm twin lead from Radio shack would be good. The inverted L seems to prefer ground radials, but a dipole or random wire may be better. If you can go up and only in one direction, could you run 300 ohm up and tap one end? this would be an end-fed Zep, i believe, and the tuner should tune it. My thoughts are that you will be better off with as much of your 150 feet of wire horizontal in the air rather than in the inverted L configuration, given your stated restrictions. BTW, my tuner is manual, but I operated from a 130 foot dipole about 100 feet high fed with RS tv twin-lead for about a year with 100 watts and did very well. 73 for now Buck N4PGW -- 73 for now Buck, N4PGW www.lumpuckeroo.com "Small - broadband - efficient: pick any two." |
