Hi All, I have a Dipole that is used as my primary. It's height varies based on the weather conditions (windy I will lower it a few feet, No wind, I will crank it up some). The maximum height is 33'. The Feedline is 33' of 450 ohm into a 1:1 balun. When I lower it, I can have around 10' of the feed lying on the ground. I understand the SWR will move, but that's fine as the tuner will take care of that. What I am wondering is, when it does lie on the ground, would I lose any effectiveness of the antenna - understanding that radiations will change due to a lower antenna?? Cheers Pete VK4CCV |

Thanks John, Sorry for the delay - I have been testing you're work. Boy, as it made a huge difference or not !!!! I just played the excess 10' on the ground and the Feed Line now drops directly to ground where as it used to be at a 45 degree angle. I now hear and send a lot stronger, but I think that's due to the feed line dropping at right angles to the dipole. Thanks again John. Pete VK4CCV |
