    I want to try something like this, but with one wire about 500 meters long on a 160 meter band only and for transmission also. I have an Icom AH-4 tuner. What do you advise?

    I can't give any advice just yet... I'm still doing testing. :) And the ladder-line project is just for reception, as I use other antenna types for transmitting.

    The data-gathering overnight hours yesterday got clobbered by thunderstorms here... it's that time of year. So I spent a big chunk of yesterday evening improving the F/B estimate calculation from WSJT-X spotting data.

    This morning, I did an SWR sweep of the antenna in its current configuration, which I should have done much earlier. But it does appear to be fairly well impedance matched across several MHz, so at least the hardware check out.

    Received my QSL card for my first phone contact with a JA station, no QRZ confirmation.

    I have played with this antenna long enough... it's time to blog about the initial results and go find something else to do for a few days. :)


    The executive summary was "it hears plenty of DX." That was good enough for me. All the stuff about collecting data, estimating F/B ratio, antenna models, etc., was all just bonus material. ;)

    But it was interesting enough for me to tinker with the idea more at a later date. Maybe I can build a slightly larger model out at my place in the country, and see how it does on 80m and 160m this next winter, when there are more stations on those bands?

    So far today unsuccessfully. My DIY earchi 9:1 antenna might be a failure.

    I’ve been testing out a Comet GP-95 triband vertical (2m/70cm/23cm) on a tripod until I can run some coax to where it’s eventually going to get mounted permanently (until the next hurricane destroys it, anyway). I haven’t had an all-mode VHF/UHF radio in over 25 years, until my brother passed away in March leaving me with a small mountain of gear including an Icom IC-9700. I’d love some directional antennas for weak signal CW/SSB work, just not sure if that’s going to be an option for me at the current QTH in the near future—or ever, perhaps, since my next QTH is likely going to be an RV.

    Today it was FT8 on 20 with the little Phaser transceiver I built a while back...4 watts. :D

    The top of one of those pine trees looks like a good spot for it :)

    I wish. It’s not on my property. Only tree on my lot that is semi-antenna worthy is impossible to use because of power lines.

    Neighbors would not let you climb up and install it? I have this tree on my new property, I am going to try and get something up there if i can find a monkey to climb it for me LOL
