    That looks great, should work well.

    6 meters was open today and I heard a guy in Wisconson (on ssb).
    Called CQ on AM on 50.4 and got no takers.

    Lots of AM fun on 80 and 40 meters today.
    The new antenna works fine on 40, the swr got better (on 40) in the rain.

    Working on the Max Power Dipole. It's an 80/40m vee, coax fed, constructed from 15 KV GTO cable to avoid setting the trees on fire. I've been dropping limbs to get it in the clear. Dropped a big limb yesterday and the resonances shifted -50KC on 75m and -150KC on 40m.

    If the wire gets close to limbs it will change the swr a lot.
    Made my first contact on 10 meters (Wisconsin) yesterday.
    S9 signal over an S2 noise level!

    Heck, elements were IN the limbs, threaded thru holes in the canopy.

    weenie insulators in the presence of a well modulated strapping carrier will point out any leakage of the magic aether,Plasma looking for a way to ruin your day,look at what the power company considers Minimum clear space for 60 cycle AC Now what do you think happens a bit higher up in frequency as far as absorption of energy.

    The aerial is constructed from 15 KV GTO neon sign cable, but I ain't taking any chances.

    The old antenna has finally come down as of today.
    Wish me luck, for it's an outstanding signal I seek.
    The next two days of engineering will tell the tale.

    The new antenna is up. Made a major change... got rid of the multi element deal. It caused a lot of problems
    with twisting and became a real hassle to deal with. So, it's now resonant at 3850 with a 2.1 vswr of 100 khz.
    Not bad. I will see if adding a couple legs to lengthen the lower portion of the band makes a difference.
    Copper clad steel wire sucks for this arrangement, period. Too much work.
