Real dipole needs: "In the lower half of the mast, there was a vertical steel tube, attached to the mast's outer structure with large insulators. This tube was grounded at the bottom, and connected electrically to the mast structure by an adjustable metal bar at 328 metres.[2] This technique allowed adjusting the impedance of the mast for the transmitter and worked by applying a DC ground at a point of low radiofrequency voltage, to conduct static charge to ground without diminishing the radio energy. Static electrical charge can build up to high values, even at times of no thunderstorm activity, when such tall structures are insulated from ground. Use of this technique provides better lightning protection than using just a spark gap at the mast feed, as is standard at most mast radiators insulated against ground." From: http://en.wikipedia.org/wiki/Warsaw_radio_tower End of discussion. S* Good evening Szczepan. The Warsaw radio mast was not a dipole. "Large constructed half-wavelength dipole towers include the Warsaw radio mast - the only half-wave dipole for longwave ever built." May I remind you that I would appreciate an answer to my question "Are you discussing resonant or non-resonant aerials, please?". It would help to clarify what you have in mind, It seems to me that you do not know what the word "resonans" means. We are discusing the earth/chassis/ counterpoise and the field electron emission. Best Regards, S* |

Best Regards, S* Hello Szczepan. If you mean the Warsaw radio mast ( http://en.wikipedia.org/wiki/Warsaw_radio_mast ) then you are incorrect. It was not a dipole. Do you mean another tower which supported a dipole aerial? I assure you that I do know the meaning of "resonant". I need to know and understand it in order to match my radio to my aerials. Kindest regards, Ian. |
