Finally upgraded to General this winter, and found a Ten-Tec Triton IV
(my first HF rig) and I need some antenna help. I need something simple that will give decent performance, and keep XYL happy. Some ideas I've come across: 1. A random loop strung in a few trees, fed with ladder line to ground level, with a balun and lightning arrestor, into buried coax 50' or so to the house and into the shack. This setup is the most aesthetically pleasing, and coax will be easy to run in the house. How much will the transition to coax hurt me here? Would I need a 1:1 or 4:1 balun? Some other ratio? 2. Same random loop, fed with ladder line all the way into the shack. Would probably give better performance, but running the ladder line in the house will be more difficult, and the XYL is less likely to approve of a wire in the air vs buried. 3. A dipole in one of the above configurations. 4. A random long wire strung around the yard, end-fed with coax and a balun. I will be using an antenna tuner in the shack with any of these configurations, and will be running a max of 100W for the foreseeable future. How much do I have to worry about the wire touching the trees at these power levels? Thanks for any help you can give - I know these questions have probably been asked a million times before ![]() -- Keith |

Keith,
Nothing wrong with any of your suggestions, but why not start out very simple, as in a dipole. It will at the very least give you something to make comparisons against. When your better half sort of gets used to the idea of wire hanging in the air, then you can make changes. You might even ask her what color of wire she thinks would be 'best'. No, it won't make any difference except that it shows that you respect her opinion... sort of. (If she reads that last part, you are up that proverbial creek!) - 'Doc |

Hi OM,
Look at these articles, some can be useful. http://www.astrosurf.com/luxorion/menu-qsl.htm Thierry ON4SKY, LX4SKY "Keith" a écrit dans le message de ...

Keith, congrats on your upgrade!!
The old saying is, any antenna is better that no antenna, so to get going why not build a quick starter-upper that will work on most all the bands. While many might call the "G5RV Dipole" as a poor antenna, it actually works quite well and is easy to make. There are a number of sites on the Internet to guide you, but all that is necessary is 102' end to end dipole fed with 31 feet of balanced line in the center. If you can tune it at that point great, but you can also add 50 coax at the end of the 31 feet into the shack. Make sure you get it up in the air as high as you can and keep it a flat top installation if at all possible. It will also work with drooping ends too, but keep the end high. On 20 Meters the antenna is a 3/2 wave dipole, and it has gain of 3db and radiates off the end of the wires. Due to the present conditions of the solar cycle, try to install it in a direction that would work well 20 as it will be your first band to work "long haul" contacts. You will find 40 and 80 to work too. BEST REGARDS, Steve K2CX |
