New General with dipole questions
I just passed my General exam a week ago. I've got a Yaesu FT-990 and made a
40m dipole with some 12g wire (each side about 33 feet long). I got it outside along the roof with part drooping off the roof. I intend to suspend it between the chimney and a tree when the universe comes together so that I am off work, it stops raining, and I get over this cold. I haven't transmitted yet, but I noticed a couple of things listening to the bands: 1. Lots and lots of noise. 2. 80m comes in quite well. Will getting the antenna higher reduce the noise? How do you account for the good 80m reception? |

This may help that (and it will certainly help with other issues), but noise comes in many flavors. Listen at different times of day/night over the next week. I bet you will hear a world of difference without doing anything else. 73's Richard Clark, KB7QHC |

How do you account for the good 80m reception? The higher antenna will increase reception. You may have it near wires or something in the house that is making noise. If you don't have a balun, you may wish to make or use one on your line. Make sure your rig is well grounded. As stated above, there are lots of things that can cause the noise. When you get the antenna raised, keep us posted and be more specific of what the noise sounds like and maybe we can help find the source. Welcome aboard and good luck. -- 73 for now Buck, N4PGW www.lumpuckeroo.com www.lumpuckeroo.com N4PGW |
