I asked a question on this thread with respect to the main advantage for hams that linear polarization has over CP. I have no resistance to change if it can be justified. I see that it can pick up signals that linear antennas cannot hear because of a 30 db attenuation where as CP has only a 3 db attenuation! Compared to what? I thought he said earlirer that it had a 3 db gain When I modeled my antenna the max gain was CP I then checked for linear gains on the same set up and they were 3 db down. I suppose I should have set it up for max linear gain and then checked CP gain on the same set up. (Made a note to myself for future). For end fed antenna, the gain max was around 13 dbi but 10 dbi seemed to be more the norm. What really pleased me was the near 50 ohm impedance feed. The biggest advantage is that people with small yards will now have no problems on getting on top band with directional antenna and be able to use the whole band! However, regardless on the ideas I have checked out on it I am very confident that hams will immediately will be able to improve it in ways I have not thought of. As with all thoughts others will say I knew that but I couldn't be bothered because once the dots are connected everything appears to be obvious. A jigsaw puzzle with all the parts turned over is tremendously hard to solve. Once you have seen the picture it is a different ball game. The antenna is extremely quiet, and as I have mentioned before the audio quality is such that I immediately look at the meter only to see it on the low side. Perhaps the CP pickup does not register the same as for linear. It is my hope that all will tackle building one this fall so that the improvement horizon will broaden while I am still around. And except for his ridiculous claims he will give no details of the antennas he makes the claims for. You are a fraud Art. tom K0TAR No, I am not Tom you are just extending your mouth. Obviously those who give me a hard time don't get to share. There are others who do not give me a hard time who get to share. If you are an outsider to every thing then I understand why you lean on the term "ridiculous" Remember the discussion on Gauss? You never did reverse your position which is against classical physics so you are an unproven quantity to most with respect to antennas and radiation. You could, ofcourse, provide a list of polarity changes upon collision instead of your dart throwing which is never accurate. Why don't you plonk me or are you just a nasty person? Maybe you can start a separate thread for just you and me so you can sound off, insult and have a good time. |
