    I am very jealous! I've never heard a ZS on SSB, but every once in awhile I see a station on FT-8, but they never seem to hear me... It looks like your doublet is a pretty good setup! how high was it?

    I run 2 160m doublets, one broadside NW/SE and the other NE/SW. Unfortunately one of the legs of the NE/SW broke off and I have to reattach it but the surviving leg acts like a long wire. I've had excellent reports off of both with very little line loss on transmit. I just wish I had trees that were more than 40-45 feet tall to act as supports.

    I run a 102' doublet fed with 450 ohm window line. It's an inverted vee and even though the center is only about 20' in the air it works really well for me.

    I use a 66ft doublet at about 25ft high,Its quite good but would be better if higher.

    Merry Christmas and HNY to all.
    I think doublet is one of the better multiband antennas, I am using one (10-40m) with decent results from qrp to 100W maximum 73

    135' with 4" spaced ladder line at 50' here. I made it from 4" electric fence insulators and tyraps.

    I was ready to build a doublet, but trueladderline had them at good prices and I bought a 125’ 80-10 version. I had a tough time getting it to work properly due to ignorance, but when I squared away the RF and SWR problems it works very well. I hardly ever use my OCF dipole antenna.

    BTW, under FAQs on trueladderline, they have Dick Cebik’s article “The All-Band Doublet”, which I recommend to all those interested. He is a SK now, but he was a great technical writer. I learned a lot from that article.
