Bird Brained Question
For the first time in many years, I'm about to put up a 20 meter monobander on
a tower. The XYL is asking questions I cannot answer, specifically relating to RF and birds. I wouldn't want to be a bird sitting on an element when a KW is supplied to it? Are my concerns valid? Gary K5QT |

I push 1kw out of a 1/2 wave horizontal dipole and the birds never choose it as a resting place. Down near the ground, it hasn't impeded the population of several Finch, Cardinal, Northern Thrush and Robin families. Jack Virginia Beach, VA |

Gary,
Given the number of beam antennas around and how long they have been up, if it were really a valid consern, there should be huge flocks of dead birds littering the yards of the beam owners. The SPCA and the Audubon Society (sp) SWAT teams would be breaking down doors, etc. It wouldn't be pretty! 'Doc |

Some just sit there and tingle, jumping around and ruffling their feathers. On my antenna, the only place guaranteed to chase away a bird is the feedpoint with one foot on each side. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Maybe get a rent a hawk or the duty owl.
Seriously -- the Ham stores sell a good looking owl to put on towers -- don't if they scare away the other boids -- but they look good (;-) -- Lamont Cranston The Shadow Knows "Cecil Moore" wrote in message ...

Woudn't the bird consitute but a tiny capacitance to ground and thus not
experience an RF burn of consequence? "Cecil Moore" wrote in message ... AA5QT wrote: For the first time in many years, I'm about to put up a 20 meter monobander on a tower.

Cecil, place a bird feeder on the boom directly in front of the feedpoint. ;^) |

Birds also sit on high-tension lines carrying many amps at thousands of
volts. Makes you wonder if it interferes with their built-in compass. "AA5QT" wrote in message ... For the first time in many years, I'm about to put up a 20 meter monobander on a tower.
