I know this is a bit farther off topic, but if the MFJ doesn’t sound like it will work for you, I can recommend the “Loop On The Ground” receive antenna. You can google it, or go to http://www.kk5jy.net/LoG/ <http://www.kk5jy.net/LoG/> for the details. I have one, completely out of sight in the front yard under my gravel and it really works. I have a noisy neighborhood (yes my home is noisy too, but I have mitigated as much of that as I can for now) and this antenna makes radio a lot easier to enjoy. Far less noise and despite low S meter readings, signals pop out clear and easier to copy. Some like to use a preamp with this antenna…I prefer it without but that’s a matter of personal preference.
It worked surprisingly well for me, and for a few other hams I know of who have tried it. It’s worth a look... 73, David - N5DCH > On Jan 7, 2021, at 5:15 PM, Tim Tucker <[email protected]> wrote: > > I have one and also have a small horizontal receiving loop around the > perimeter of the property with the intended purpose of picking noise > generated by the neighbors' stuff.
