Would it be possible to get some more information on your antenna system? If it is not too much trouble? Is it basicaly the fact that the 2 antennas are phased that cuases the null? Do you have a plot pattern that the antenna exhibit? Very interesting all this about noise cancelation Thank you Laurie PaulC W1VLF ----- Original Message ----- From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Sent: Tuesday, January 23, 2001 5:48 AM Subject: LF: Re.
