Re: Remote_Tuned_Loop By Portstevos
Hi JR, Hmmm.....if i knew earlier the Kyle KOLR design would have a higher noise floor, i would opt for your Pre-amp design which i choose not to earlier as i thought Kyle's circuit looks more

Re: Remote_Tuned_Loop By Portstevos
The ONLY real advantage a Wellbrook (or any other amplifiied untuned loop) has over a tuned loop is a wide range of operating frequencies and a tuned loop has several advantages over an untuned loop

Re: Remote_Tuned_Loop By Portstevos
Would this new system be as good or even better than the very costly (excessively expencive) Badbrook antennas? If so, I for 1 would be very much interested to build 1 or more of them! Aimo dldorrance

Hi Alan, You are not the only one who is confused. I am at a disadvantage, as I am not able to read the text which accompanies some of his diagrams (too small). However, looking at the two amplifier

Hi Dave, please correct me if i'm wrong as i'm just a beginner in loop antennas.... in summary, if i were to build a remote tuned loop based on Kyle KOLR design, the tuning & preamp circuit board will

Re: Remote_Tuned_Loop By Portstevos
Across a tuned loop if it is a high-input-impedance pre-amp (i.e. a JFET-input amplifier); or in series with the loop and its tuning capacitor (if any) for a very-low-impedance pre-amp; otherwise use

Re: Remote_Tuned_Loop By Portstevos
Hi Alan, Please see inline responses. Dave WA6YSO The pre-amp is placed on the main loop. The main loop (inductor) and capacitor (here a varactor setup) forms a parallel resonant (tuned) circuit. In a

loop antenna questions
Hi Scott, About a year ago I put up a 204ft G5RV from the roof of my rancher to 2 trees in a vee 102ft long about 65ft apart. The heighth is about 20feet. This worked pretty well on most bands. About

Antena Software. I have made a list (6 months old ;-) that collects all software that works for linux. Once you've setup a linux box with debian/ ubuntu, installing is a matter of clicking.

Hi, Scott While I am not an expert on horizontally-oriented loops (or any loops, for that matter - hi), I have also been researching them and have found a few web sites that have good designs. I guess

HI, if you have the demo EZNEX program (free to use) I will send you a EZNEC fille you can put into your program and it will display some of the loop antennas in question.... I suggest you try a K9AY

Re: loop antenna questions
Hi Scott, Generally speaking low horizontally polarized antennas ... loops or dipoles are cloud burners .... That doesn't mean you won't hear some distant stations when conditions are really good ...
