Here are some pics of my modified K9AY rx loop antenna that I'm getting ready for winter.



This picture shows how I've mounted the modified loop on the back wall of the garage using some old porcelain stand-off insulators.

There is about 85 feet in the loop much like the K9AY triangular configuration.

You can see the relay box (Array Solutions) at the bottom center of the pic.  The wall is oriented NE-SW so that was good luck.  I'm obviously only using the single loop so the NW-SE terminals are unused.

I couldn't easily get behind the oil tank so the shape is a little irregular at that point.

Here's a closer look at the relay-termination box where you can see the stranded copper loop wire. I drove a few 10 foot pieces of copper pipe into the ground.  Hopefully that will be enough of a ground for it to work effectively.

You can also see the coax (RG-8X) and control cable which come out of the bottom of the box.


This is another look at the control box and the NE wire heading off to the first stand-off insulator where it turns and goes up the wall.

You can also see the two 3/4 inch 10 foot copper pipes that are supporting the box as well as providing a ground.


This shows one of the porcelain insulators way up under the NE eave.

I'm hoping that being under an aluminum eave won't adversely affect the loop's performance since the eave is not grounded.

This is another view of the path that the loop takes as it goes from insulator to insulator around the back wall of the garage.

The copper wire didn't show up very well in the picture so I traced the path in yellow .

Looking very carefully you can see my OB9-5 OptiBeam on the 80ft tower in the background.

Here's the bottom of the SW loop wire making the turn to go to the control box.

I always wondered what I would do with a pile of Johnson porcelain stand-off insulators.  And to think that I was going to get rid of them.


At the time that I put this up on my website, I hadn't completed hooking anything up in the shack yet so I can't say for sure if or how it works.  I'm not going to have a really good idea of how it performs until the 160m season starts I suppose.  I'll update this page as I make progress.
