I set up a 160m loop in the yard to try one out from all the great reading I did regarding the antenna.
For me I can get it to tune with no problems except the RF in the shack is terrible. I ran 450 ohm ladder line from the antenna to my balanced line connections on my MFJ 962 d tuner. As soon as I connect the ladder line the RF is bad, basically everyone states that I sound like I am in a jet airplane. Now there is also a bit more to the story as the loop surrounds the house as that is how the trees are plus the dipole is also very close to one of the edges on the inside of the loop. So I dont know if the problem is that everything is in the middle of the loop, or running ladder line into the shack is a bad thing, maybe the tuner internal balun is not the correct one. Bottom line is the K3 was real unhappy with this scenario so the ladder line is pulled out of the shack and coiled up on the tree next to the loop outside. One thing I have researched this morning is that I need a current balun and I should have it external to the shack and run coax between it and the shack. Also I should have the shield grounded like I do with the dipole to direct ground. So I thought I would share my current failure while I ponder my next move or give up on the loop. Ok I wont give up, YET!
