![]() HI I want to put a dipole for 20m in my garden. A tree and the home roof will be ok to fix the extremity. My problem is the feed point : If IA center feed it , the feed line will just hang at the center of the garden, something not acceptable by the YL :-) So I'm looking for a way to feed it by one "side". I could endfeed it, but impedance matching is not so easy at such a high impedance. Then, after reading lots of post in this newsgroup, I read about the sleeve antenna : generaly a vertical dipole where one leg is a sleeve. Coax enter in the sleeve to the center feed point. I think this antenna could work horizontaly and for HF and solve my problem. Now, hanging horizontaly a 5m long metallic sleeve is surely not a good idea, but at HF , I thing that man could replace the sleeve by some wire cage. So I end up with the idea of a cage or biconic dipole , with the coax entering horizontaly in the middle of the cage to the center. What do you think of this idea ? How many wire for the cage 2 (a bowtie), 3, more ? Do you have a better one for my particular constrains ? Lots of questions, but I'm sure you will have lots of answers ! Thanks in advance Thierry F4DWV |
