    Nice gag. Stealth antennas could have strange materials and shapes. A good aluminium trashbin in front of the house, is when tuned, usable too. It works, but its poor and childish.

    Multiband tree antenna comprised of several current probes | TechLink (techlinkcenter.org)
    "In 1904, General George O. Squier, chief signal officer, developed the theory that trees were nature’s own wireless towers. During World War I, his theory was tested and it was found that it was possible to receive radio signals through a tree. Since then, experimental tree antennas have been developed for various frequencies, some outperforming conventional whip antennas.

    Navy researchers have invented a novel technology that can turn a live tree into a multiple frequency, broadband antenna. " More at link.

    Not a lot of corn in Alaska, trees on the other hand....

    The feedline is radiating due to common mode current not the tree/vegetable.:eek:

    Kevin, we'll have to try a contact sometime. I'm originally from Marshalltown, followed by DSM/Ankeny. I have relatives in the Ackley area. I currently live in Korea as HL1ZIX. I have been hitting a few US-based stations in the midwest lately, although that greyline window may close up, soon.

    I would like to see someone attach their radio directly to the plant without the coax and see how well it works. If a tuner is involved, use the shortest possible coax jumper. I think W4HM nailed it in post #22.

    That would be great.. I generally work QRP SSB 5w or less and can QRO to 10w if needed.. I recently made a contact to a Japan station with 10w SSB so when the conditions are good I know it can be done.. I'll start listening to some SDR's in your area and see if I can hear myself... Thanks for you comment..
