I live in a neighborhood that as the years have gone on has added a number of new homes. This has increased the electrical "noise" for me where S1 or S2 on 80 meters 6-8 yrs ago is now S7 to S9. At this point in time I don't have the room for a K9AY setup. I can only "dream" of a beverage. I have a Timewave ANC-4 which works very well on 40 meters as I can null out ALL the "noise". Not so on 80 meters as it only knocks it down 2 S Units. At best I have an S-6 noise level. This leads me to believe that I need a separate sensing antenna for 80 meters. Anyone have any ideas for this problem? Is this thinking correct? I have been looking at low noise receiving loops and other low noise antennas. Wellbrook athttp://www.wellbrook.uk.com/seems to have some interresting possibilities, but some of the reviews I have read have made me hesistant to purchase any of their products. What I need is some serious input from anyone who has any experience and knowledge in dealing with low band noise issues. As I am now space limited due to all the new neighbors any solution would need to take this into consideration. TIA What kind of sense antenna are you currently using? I use an active whip as a sense antenna (specifically, an H-800 "Skymatch" antenna) and it enables me to squash *any* noise on 80 meters using my ANC-4. |

I use a small dipole like antenna where one half is at 45 degrees the feed point is a few inches above ground and the other side runs paralle to ground about 1-2 inches above ground. I think the whole sense antenna is about 6 ft long and runs in a straight line. I will look up the H-800 on the web. Did you try various antennas and configurations before you settled on the H-800? What made you decide to go with the H-800? I tried different "antennas" and configurations, for this location this has worked out the best that I have found. I do realize there could be a zazillion different antennas and configurations. |

The H-800 gives me the best results from among all the sense antennas I've tried, though of course this could be a function of the particular kinds of noise present at my QTH. I will say this. Because I live in an urban area it's been my aim to defeat RFI in every way possible. I use one of the Wellbrook loops and that helps, but nothing has been as big a help as the ANC-4 WHEN MATCHED with the right sense antenna. Part of me suspects that the ideal setup, at least for me, would involve having a couple of different active whips to switch back and forth between. I think the H-800 does well on 80 meters because it's quite sensitive there. However, it's quite a bit less sensitive on, say, 20 meters and I'll bet I'd get better results using a different active whip, or perhaps a wire, on higher frequencies. |

I couldn't quite see buying an H-800 just for use as a sense antenna, as they're fairly expensive, but I've seen them go on ebay for not too much. Active whips can be real noise magnets. A huge disadvantage if you're using one as your receive antenna, but a big plus if noise is what you want it to hear! |
