Low band hams are very aware of "sea gain" minimum salt water attenuation at low angles. The signal will not  produce a perfect circle as the posting shows. 73 Bruce-K1FZ www.qsl.net/k1fz/beveragenot

Better, these look more like measured signal levels, The sky wave plot looks like a use of a drafting compass.  Actual measurements would reflect slight aircraft measurement irregularities. Thanks fo

Through the woods is ok. No cutting needed.  If above ground,  580-600 length is good. If BOG, 200 feet is optimum length for 160 meters in most locations. If off ground, need to be high enough to pr

True the lower velocity factor does bring the frequency down lower with snow & leaves. In my case found that 215 feet may be best in the dry month in summer, 200 feet is best on 160 meters year aroun

I can believe this. If you think of earth as also capacitance to the wire,  the optimum  frequency would go much lower. Using radial wire grounds instead of deep ground rods, become part of the probl
