I will tell you how mine worked it had varying heights using existing supports @ 50/40/25/18' and a very ragged rectangle. Ladder Line is a PITA to use and not necessary at all. I used coax all the way and it was fed from a corner at my tower close to the house to a tuner it worked from 6-160m. It was the best antenna that I have used and I have a lot of antennas for North and Central America on the low bands 30-160m. In fact in the first 160m SSB Contest I worked 43 states and 19 enties under poor conditions it was excellent on 80/160m.
I had yagis and beams for all bands 432-40m and verticals for 440-160m as well and dipoles covering the same so I did a few to compare to. It is known as a quiet antenna the jury is out here on that, granted it's not a great DX antenna but did work a little a few times mostly EU's. If you want a good low band antenna for NA,CA it's well worth putting up and 30' will surprise you I think all you need is wire and a balun, coax.
