This is almost certainly uses an ephemt device. They are great ... above 50 MHz. At HF and below, they have fatal 1/f noise. Rick N6RK

Hola Horacio,? This amplifier, you link here, is for VHF and he is looking for Long- , Medium- and Shortwave so he can't use this one. Best 73? Rob?PE9PE? Horacio Nigro <hanigrodx@...> ,

Why not try one of the Wellbrook preamps? ( http://www.wellbrook.uk.com/antennashop/index.php?route=common/home http://www.wellbrook.uk.com/antennashop/index.php?route=common/home ) 73's Egil -

Hi Jose, If you are really interested in receiving weak signals, tuned loop will work better than broadband loop. 73, Mike

Jose, I would recommend that you look at this loop antenna out of interest. 1.. A Wide Bandwidth Active Loop Receiving Antenna. - QSL.net

What "Loop" no info in your post! 73 Adrian KF7DYU

Jose, I would recommend that you look at this loop antenna out of interest. There are many ' imitations ' around but it does really work and is cheap to build. Good luck with your project.

Loop Antenna News and Information Forum Low noise preamp for wideband loop Friends im searching for a very low noise wideband loop preamp, is for use in areas with very weak Mw signals, my loop is

Yes, it's more suitable for short whip (monopole) antennas that require a high input impedance amplifier. Loops have a very low terminal impedance, so a balanced common-base amplifier is more

The website doesn't mention the input impedance of the amplifier, but it looks like it is fairly high. This is not optimal for the loop, which works better when loaded with a low impedance. You can

Hi Steve, I used a version of this circuit many years ago as a relay-switched preamp for a homebrew communications receiver, and it worked extremely well ahead of an SBL-1 mixer. It's essentially

Does anyone know where I can get the adapter from sma connector to a BNC? Gary WA1TJB

Looks really interesting. ?Might just order it and try it with my FSL just for fun. ?I already have an 18 db preamp that works very well, but I always like to play with stuff. Gary WA1TJB

Unfortunately not John. I do have a Pixel Pro 1B now. No comparison, the DX-One was WAY better. In fact I think all in my DX Engineering Active Vertical is better than the Pixel as well. Maybe I

Does anyone in the group have experience with this product: https://www.sv1afn.com/j310preamp.html It looks to be very well constructed and suitable for a loop preamp. Steve / VE7SL

Ian, Did you by any chance have a Wellbrook 330S or 1530S in the past collection of antennas you could compare the RF Systems to? Thanks, John
