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 Hi, Tony. Several years ago I decided to put my ham radio station back on the air. The tallest trees on my property here in Central Oregon are junipers, about 35 feet tall. I managed to get the ends of a 40 meter dipole up towards the top of the trees. It was fed with coax and a balun. Petty noisy. Later, I decided to try the old tried and true folded dipole using 300 ohm TV twinlead and an antenna tuner. This time I was able to get a 75 meter antenna up into the junipers. When I connected the antenna/tuner the receiver, there was no noise. I actually went outside and checked for something shorted. Then I checked the antenna for continuity with an ohm meter. All was ok. This was mid-day and there were no stations on 75 m. I tuned other bands and there was plenty of activity and very little noise. Later I began to hear stations from the mid-west on 75 meters. Bottom line, I think if you can find the room for a folded dipole or other loop type antenna you will be surprised how much your noise level goes down. Best of luck. Paul, KD7HB |
