[Antennas] Variation on coaxial dipole antenna

Fri Jan 28 00:50:31 EST 2005

That seems simple enough. My thoughts are to have the material available to
make a vertical dipole or horizontal dipole as needed. 
I hadn't thought of the balun or unun. 
Thanks again.

If so, yes, it will work. Both need to have something to de-couple the
coax......1:1 unun, 
coax choke, ect. Failure to de-couple the coax will result in RF on the out
side of the coax.
