Perhaps magnetic loop was an incorrect term - shielded-loop is better.
Yes - there are better low-band RX antennas. I also have a Hi-Z 3 element
vertical triangle array. It works, has directivity and decent rear rejection.
However, my triangle array has higher S/N than my shielded-loop.

A loop such as that has a very narrow null at very low angles, and
therefore it's usually not very effective for anything except for local RFI
or another local ham. For power line or nearby QRN, it's useful. But that's
about it. There are much better RX antennas.

Hi JC,
Not all vertical arrays are mono band. A well built 4-square on a 60 foot
per side can do a stellar job on 160, 80, and 40 meters while extending well
down into the broadcast band. The 3 element as well as the 4-square based 8
element on an 85 foot diameter circle will do the same

Look into a magnetic loop such as the design by N6RK as described in a past NCJ:

That's for me is a very low performance. The good Horizontal Flag can dig
signals 22 db below the vertical TX array. A simple K9AY does what you
mentioned too.

Taking the chance to show my ignorance :)
Here is my thinking. While adding cores along the length of a beverage may
make it appear electrically longer, how can that help its performance?
I'd think that the true mechanical length is what matters. Each inch/ foot/
meter of the wire is what
21 matches
