Some topics ago somebody analised the antenna temperature. The end of the dipole should be the hottest. Have you any observations in this subject? Aside from analysis, has anyone measured this effect? Of course. The antennas on animalls have temperature rise below 15C. Is it to be expected in highly efficent antennas, or just inneficient ones in which there is substantial heating already? Is this assuming that the heat if given off is enough to raise the temperature surrounding th eantenna above 0deg C? I do not know. I am asking you (antenna owners). Working antenna is hotter than at rest. Which part of the dipole is the hottest? S* |

Which part of the dipole is the hottest? the center part is the hottest. If the junction with the transmission line is poor. As you see I cannot accept your answer because it do not fit to Tesla's radio. So the next question: The simplest dipole is made from a transmission cable. It is enough to stretch the wires in the oppsite directions (like arms). The no junctions. Which part is the hottest?: -Transmission cable, -The first part of the arm, -The end of the arm. S* |

Which part of the dipole is the hottest? the center part is the hottest. If the junction with the transmission line is poor. Babbling nonsense and shows you have no clue as to the meaning of voltage, current, and power. As you see I cannot accept your answer because it do not fit to Tesla's radio. So the next question: No, you can't accept the answer because it doesn't fit your demented preconceptions. Tesla died insane a long time ago. The simplest dipole is made from a transmission cable. It is enough to stretch the wires in the oppsite directions (like arms). The no junctions. Which part is the hottest?: -Transmission cable, -The first part of the arm, -The end of the arm. S* The above is just babbling word salad and the question has been answered, whether you like the answer or not. -- Jim Pennino Remove .spam.sux to reply. |

S* i know better than whatever you think you understand of tesla's work, and also have at least 60 years of research after he died to support it. the first part of the arm is hottest, just like the center part of the dipole that is not heated due to a bad connection... maybe you make bad connections to dipoles, i don't! |

Michaels answer was the best: "Aside from analysis, has anyone measured this effect? Is it to be expected in highly efficent antennas, or just inneficient ones in which there is substantial heating already? I have found that ice (hoar-frost) and rain do not disturbs radiating. But the ice-water strongly. The ice-water is in a moment when the hoar-frost is melting and in the pores is water (normally is air). It is agreement with: " "In fact, most dipolar solids exhibit extremely small dielectric losses since W tends to be extremely large. Water-free ice, for example does not heat significantly under microwave irradiation." I have found also that the temperature is measured for antennas for annimals. The temperature rise must be below 15C. Of course they know the details. So no additional questions from me. S* |
