So instead of a "T" between the trees where the top is a dipole and the vertical element is the feedline, why not a "T" between the trees where the top is a support rope and the vertical element is a monopole? Given that, I've gone to all the trouble of putting up a dipole. Why would I choose to put up something inferior to a dipole? Plus, with a vertical, I would have to lay in a ground plane only to make my noise level 2 S-units worse than with the dipole. Where's the ROI? Do you think a couple of trees 65+ feet away from said monopole would suck up all its radiated energy? And if so, why wouldn't they clobber the much closer, high-impedance ends of the dipole? Because the trees then act as part of the end-hat circuit which is a good thing. I never operate my antenna in a null. This is quite a remarkable feat! Do you only talk to a list of favored stations that are known to lie in your lobes? Yes, that's why I placed the lobes where they are. Or do you refuse to answer a list of stations that lie in your nulls? I don't QSO with weak signals. Life is too short for QRP. I also don't drive my pickup one mile per hour even if I only average driving it one hour per day. Seems by your logic, I should always walk since I can walk faster than the average speed of my pickup over any 24 hour period. :-) I'm afraid this analogy is so strained and inapplicable that it doesn't really need a response. It's the same logic. You are arguing that the average radiation pattern is what is important and not the directional gain while it is performing useful work. So to be consistent, you must also argue, that it is the average speed of my pickup that is important and not the speed while it is performing useful work. Since the average gain of a beam is about equal to a vertical, do you advocate getting rid of all the beams? :-) -- 73, Cecil, W5DXP |
