Well if you took your trees away and put up an inv L of the same size you would have a bigger signal (field-strength) than would be given by the loop. Amongst the trees the loop works better. Its location, location, location that matters, not old wives tales, or even old commercial antenna books (they dont put "little" antennas up in the middle of forests !! for good reasons) Keep pumping the LF watts out man !! :-)) Alan G3NYK ----- Original Message ----- From: "dave.riley3" To: Sent: Tuesday, May 05, 2009 11:02 PM Subject: Re: LF: Re: 600MRG> T or F? > A big black ferrite that works down there... > > Bifilar wound 1:1 > > > ----- Original Message ----- > From: "Stewart Bryant" > To: > Sent: Tuesday, May 05, 2009 4:36 PM > Subject: Re: LF: Re: 600MRG> T or F? > > > > Dave > >> > >> Exhibit #1 www.radiocom.net/600M/LOOP109.jpg > > > > An interesting design - what are you using as a broadband match in > > xformer for the 200KHz - HF? > > > > Thanks > > > > Stewart/G3YSX > > > > > > >
