Homebrew EH antenna for 40M band. Post 1814.

Here's an interesting antenna experiment from Paul (OM0ET).  In this video, Paul builds an EH antenna for the 40 meter band--the antenna is based on a design by WB5CXC (SK).

Although the build was successful, Paul admits that the antenna may be of questionable value, since "this antenna has the problem of a strong returning RF in to coax...this is a big problem with resonant frequency stability due to this problem...This is the reason why I never tryed (sic) this antenna in a real outdoor conditions (sic)."

Of course, your results will vary, depending on the materials used and the general environment in which the antenna is placed.  If you need a better and perhaps  safer antenna, please try a magnetic loop or indoor loop antenna.
