Hello all. After a year, more or less, of using my homebrewed loops, I've decide that I need to improve them. I have rather cheap RG-58 cables which I think are susceptible to picking up RFI, and ferrite chokes haven't really helped there. So I need something that's better shielded. My question to HFU at large is, what kind? I'm leaning toward RG-6 quad shielded.
I've also decided to alter the larger loop for lower coverage. I was advised that additional loops was a good way to do this, but my question there is, Do I use the same 15' length of copper line and turn that twice, resulting in two loops about 7 1/2' in circumference, or get a 30' length and turn that twice, so that the loops have the same 15' circumference that it currently has? (And if the answer is two loops of 7 1/2' circumference, will I also need to change the coupler's circumference, currently 3', down to 1.5' to maintain the 1:5 ratio of coupler to loop?)
If anyone needs to familiarize themselves with my loops, I posted about the bigger one last year.
