4. Re: LF: 500 kHz loop antenna ? (score: 1): Author: John Andrews <[email protected]>; Date: Fri, 11 May 2007 13:47:55 +0000; Rik, Just a little interesting information... My 1159 m^2 loop shows a feedpoint impedance of 1.8 +j215 ohms at 137 kHz. It measures 53 +j1060 ohms at 505 kHz. If the FCC ever grinds out a license fo; /rsgb_lf_group-archives/html/rsgb_lf_group/2007-05/msg00373.html (11,580 bytes)
5. Re: LF: 500 kHz loop antenna ? (score: 1): Author: "Dave Sergeant" <[email protected]>; Date: Fri, 11 May 2007 11:10:05 +0100; Interesting thought Rik. When I finally get my 10m vertical resonated I will see how that performs and if it fails I have two choices - my 110ft low long wire (terrible on 160m) or put my 136kHz loop; /rsgb_lf_group-archives/html/rsgb_lf_group/2007-05/msg00374.html (11,724 bytes)
6. LF: 500 kHz loop antenna ? (score: 1): Author: Rik Strobbe <[email protected]>; Date: Fri, 11 May 2007 11:52:24 +0200; Dear all, did anyone try a loop antenna (for transmitting) on 500 kHz ? As the radiation resistance of a small loop increases with the 4th power of the frequency a loop should be about 22 dB more eff; /rsgb_lf_group-archives/html/rsgb_lf_group/2007-05/msg00375.html (10,438 bytes)
