    I have a close set up like yours and have the same wishes. If I could rotate my yard it would be great. The lower end is on a 40 ft push up pole and the high end is 75 ft telephone pole. It works great. Mine runs about 10 deg off of North/South.

    The discussion on the EFHW was interesting and welcome but for a detailed and concise description of its theory, practical construction and behavour I haven't found anything better than WA7ARK's presentation:

    My next homebrew project. I've collected all the bits needed for the EFHW that Mike describes and just need to connect them together. :)

    Hi Ken,
    Also consider WSPR receive-only on 136 and 474 KHz.. Grab your longest wire or vertical antenna and place your internal or outboard tuner in bypass mode for max noise, and decode overnite. 73, n6spp-cm98
