Thus I would like to experiment with one of the whips to run a 2 meter. I could have easily did a 1/4 wave vertical but thought that 5/8 would be better experiment. the loaded 5/8 ungrounded as NM5K posted just might be what I need. I was looking for how many turns of wire might do the trick. Problem is I dont have a GDO to get the right turns so thats why I was hoping to find someone whom ad done it before  .I saw an antenna similar to what you are wanting to do. I think it was 47 inches long. The coil will only be a few turns. I don't recall the number of turns on the form for that antenna, but it was only about 2 or 3 turns. I would start with 3 turns and check the swr and trim the turns for a low swr. Thanks, My figuring was all wrong . Just so everyone knows, its a standard Firestik wound loaded about 4ft long. So its not base loaded, they distributed the coil from top to bottom (tighter winding at the top). Ill experiment when I have time. W7PSK Ive experimented with many wire antennas over the years, but never loading types. Thats why I came to the experts . |
