Loops are touchy by nature and you have to be very sensitive to the surroundings-metals, bodies (yes your body in close proximity will affect tuning). I use a small antenna analyzer to get it close and sometimes I have to adjust and step away from the antenna,take a reading and readjust I then follow up with adjustments with the radio connected for maximum band noise Also it needs to be a minimum of one diameter of the loop above ground,and more is better within reason. Is there a close ceiling that limits the height of the loop? Getting it in the clear is important,although with patience I’ve made contacts even indoors. Pick the bands carefully for propagation and as mentioned earlier tune for resonance. I’m strictly a QRP CW guy (5W Max) and have had good results by carefully adjusting to the surroundings and conditions. I have 2 loops-the AlexLoop and the W4OP. AlexLoop is good for 20 M and up while the W4OP is very efficient at 30,40 and 60 M. It’s very well made and an excellent design,although not the best option for backpacking as it’s a bit heavier.
