Your car wears it's tire mittens, yet sputters at porch lights due to excessive carbon buildup on the various intake valves. The carbon expands as it heats up, and then the valves refuse to seal, which leads to a loss of compression, which leads to a poor operating ability as it passes go to collect it's $200 while operating 3A at field day. I asked my cat what is likely the cause for this peculiar phenomenon, and it laughed at me and pointed to the northeast. Sorry, looks like random garbage to me. |

It looks just like the random garbage that comes from your keyboard. I just wanted to show how your gibberish looks to anyone that has even half a clue about short radiators. Just the title of this thread alone is a false statement. |

Just the title of this thread alone is a false statement. The fact that short antennae are poor radiators is borne out by advanced EM texts. Might I remind you that in your case the fool is better advised to keep his mouth shut rather then open it and confirm to all? |

Being as such bafflegab fodder does not exist, I shall not hold my breath waiting for such information.

Well, prove I'm a fool, you braying jackass. The ball is in your court. Show the tests, and the results which show a small antenna is an inefficient radiator. Until you do, you have no room to remind me of a damn thing. Thinking people all around the world have known for many years that even a small radiator will radiate nearly all power that is applied to it. So where does that leave you? In an isolated rubber room? |

Over here in Brit, there is a glaring illustration of the abject failure of the new examination scheme, in the person of Stephen Thomas Cole. M0TEY, who had chosen his callsign as a memento of his days as a CBer. Cole is completely untechnical and all his posts (including those to this NG) are abusive and attention-seeking. You are indistinguishable from Cole. |
