When i start looking at the low bands for antennas I first go to Low Band DXing then W8JI's website and study the ARRL Antenna Book for what answers I can find. If I still come up short (not often) start doing Internet searches with several topic lines. There is a site that has nothing but traps building and modeling that I have came across sometime but can't remember where.
Have used several different loops I do like them a good antenna but all were full size and most for 160m and used for all bands.
