There's something wrong with the bugcatcher feedpoint impedance unless there was a matching coil, cap, or transformer at the base. Did you have any coils shorted out on the loading coil for tuning purposes? Shorted coils lower the Q. -- 73, Cecil http://www.qsl.net/w5dxp Nope Just the Hustler base, the entire bugcatcher coil and a 103 " whip. I expected it to be lower in impedance at resonance. Now I've ordered a BBS screwdriver to see if the copper base is better than aluminum. Copper has about a tenth the resistance of aluminum, we shall see. H. NQ5H |

Is the Hustler base the one that hinges? If so, it might not be conducting properly. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Yes it is the "big one" but I suspect that, since I cobbled it together,
that R is a big issue. I don't care since it isn't a realistic solution. I used it "parked mobile" in 1970. Comparing the Nott with the Tarheel should be fun. H.

H.,
When you find out that the aluminum/copper base makes no difference at all, can I have the one you don't want? 'Doc |
