A very interesting paper of yours, is it likely that there will be the= same=20 interaction between a T antenna and the PA0RDT Mini Whip? 73. Ken M0KHW ----- Original Message -----=20 From: "ALAN MELIA" To: Sent: Sunday, December 27, 2009 11:51 AM Subject: Re: AW: LF: Influence of a TX antenna to a small rx antenna Hi Stefan I hope it does not give you indigestion :-)) Good luck with it.....all LF sites are different so in general require= =20 different detailed solutions. It seemed generally to be sufficient to= =20 de-tune the unused antenna to reduce the interaction to low levels.
