    it does... but the OP said he has 40 foot towers

    that is plenty to get the guy going.

    Not for 80m or 160m DX, it doesn't.

    There's a good reason W6AM's wire antennas were up 120 feet above ground.

    W6OGC probably remembers Don; I sure do and met him twice.

    A loop at 40' above ground is a cloud-warmer on 160 and 80, although it starts coming into its own on 40m.

    not a 2x wavelength loop

    I just put up a 40 meter delta loop fed with a home brew 4:1 balun. Only up about 15 feet but seems to work really well. Third contact was with Hawaii running 100 watts.

    No, they were all multi-wavelength rhombics.

    I'm fascinated to know more, as this seems to fly in the face of what could be considered conventional wisdom.

    I don't have room for 2X on 160 but could do 2X on 80 if it would free me from the curse of low height. I have 2X on 40 of course and can't say it seems that much better.

    here is a nice article about it

    As your article discloses, the patterns are studied at 50 feet above average good ground.

    I guess that is better than 1/4 wavelength on 160 as is generally regarded as about the minimum for non cloud warmer status.

    Multiple wavelengths at low heights will create unpredictable amounts of nulls and lobes. With any luck these will kinda squish and flatten in your favor.

    Just get some wire up in the air and get on the air. Odds are, whatever you put up will get you contacts and you can take it from there.

    Virtually all wire antenna designs have been around for at least 80 years. You can wait to get the whole 80 years sliced and diced here or you can just get on the air.

    Every first wire antenna is just a starting point; a work in progress. Even some of my early mistakes actually worked pretty well.
