The Dove Experiment

dove.jpgPigeons are sensitive to electromagnetic fields, so they say. True or not? Time to put this to the test. I have a regular visitor, a turtle dove, who takes a daily nap on one of the radials of my 5/8 wave vertical for 10 meters. He/she must really like it there, almost every day, the bird is present.

I set my Yaesu FT-840 to 29.300 MHz, FM mode, and the initial power output to 5 Watts. No reaction. At 10 Watts, the bird raises its head and starts to look around a bit. At 15 Watts, my feathered fan becomes restless and starts to hop around. At 25 Watts, the turtle dove takes off.


I repeated the test a few times, just to be sure. On average, the turtle dove leaves my antenna when the power is around 25 Watts. Amazing, these animals.

  1. LOL!! Vy funny..

    At this QTH i use a discone for 2m VHF. This thing has elements all over the place- up, down, sideways. A haven for birds.

    I don’t use 2m very often, but now you mention it, 25w is capable from my 2m rig…

    Plus, it might make the site of bird poo on my driveway a little less noticeable.

    If you go to QRz com and type in my callsign, look closely and you’ll see the discone on the apex of the house. I recall 16 newly hatched blackbirds on there this spring….if only i’d known 25 watts was a good deterrant!

  2. Hi Colin,

    if birds other than pigeons are sensitive too: I have no idea. It’s worth a try!

    I use a discone too (the stainless steel HAM version from Diamond) as an addition to my X50. It’s a funny little thing, designed in such a way that you can use it on 6 meters, 2 meters, 70 cm and 23 cm.

    When you look at the ray diagram, you will see that a discone has horizontal components too. When listening to SSB stations in the 144 MHz band, the discone proved to be a better choice.
