WARNING THIS LINK CONTAINS TEAR-DOWN PORN

This is a thread I started over on QRZ.com (Yes I was invited back there by popular demand.)
The posting is complete with pictures and such along with my review of the product.
So check it out and we can discuss it here or over there if you wish.

Why is your antenna right next to a power line?   :o

It's not so close. Look at the perspective, long telephoto lens :)

Nice, I once used a marine crossed loop DF antenna for picking up ELF/VLF signals, mainly Alpha and Omega navigation signals. It was nice how you could null out any interference by rotating the antanna, wish I had kept it.

I have three loop antennas (Sony AN-LP1, Wellbrook ALA-1530+ and MFJ 1788) and it's amazing what you can achieve with so unobtrusive antennas.

That is not a power line, one end of my doublet. The nearest power line is fifteen feet away.

That brings back memories of my old Navy regenerative receiver (14-600KHZ)

They work really well, this one has minimized my noise situation.
Now if I could knock it down a few more DB.....
