Current across the antenna loading coil - from scratch

Turning aside what is obvious (that having been answered separately); we can observe that one coil of a fixed pitch (it seems to bear repeating for Cecil) does not exhibit a Vf increase from 0.02 to 0.2 by cutting the coil down to one turn. Cecil needs to accomplish what is doable instead of turning to radical solutions that fail early. |

You are agreeing with what I have been saying so your argument is with Gene, not me. What I have said is that as the pitch is decreased the VF increases and vice versa. -- 73, Cecil, W5DXP |

Now you can argue with Gene. :-) So you didn't say it? You seem to have difficulty expressing concepts then, don't you? I bet you can't even restate what you THINK has been said to say it yourself. No point in waiting, because I won that bet already. |

You can't change the Vf by shortening a Vf = 0.02 coil, hmmm? Remarkable shortening of your own theory there. Perhaps you might want to try again using real numbers. Simply because you play the pity card of forgetfulness (blaming your reader usually as a bluff) we will reprise the question once again: Asked: At one length, one coil exhibits Vf = 0.02, reduce the coil length, what length for the SAME coil would that be to render Vf = 0.2 for instance? 1. We are not changing frequency; 2. we are not changing diameter/lambda (nor in fact changing diameter OR lambda); 3. we are not changing pitch/lambda (nor in fact changing pitch OR lambda). SAME coil means the one being offered, and being shortened - all other provisos stand |
