I know it's summer and noise is bad now, but I have it all year long. I have several vlf receivers & use my 160m dipoles as a receiving antennas for 630 & 2200, they are on separate feedlines N/S and E/W. Noise it tolerable on 160m but starts to pickup at the AM band and increases as I drop. Years ago I could easily pickup LF AM brodcast stations from Europe in the winter, this past year noise was so bad I gave up. What can I do to fix this? Now For now I am interested in receive only antenna/setup.
Try looking into a magnetic loop receive antenna. DX Engineering has one for under $300.00. It is possible to build your own but special care must be taken to design and build the preamp for this type of antenna. BTW..... MF 300 KHz to 3,000 KHz LF 30 KHz to 300 KHz VLF 3 KHz to 30 KHz Tom WA4ILH
If you’re really interested in low noise antennas for the lower frequencies, you may consider picking up a copy of “Receiving Antennas for The Radio Amateur” by Eric Nichols, KL7AJ. Eric addresses a number of low noise antennas in an easy to ready style. Available from the ARRL book store. (no, I am not a salesman for KL7AJ or the ARRL) Tom WA4ILH
re: "I know it's summer and noise is bad now, but I have it all year long. " Are you living next to an electrical substation or an aluminum smelter? If no, then there might be hope for you, if you can find specific 'noise sources' in your neighborhood. The use of direction antennas (like a vertical rx loop) can provide some relief, since terrestrial ground-wave emanating sources can be nulled.
