Here is a intetesting Antenna to think about
- Thread starter AudioShockwav
- Start date
I like to think of the DDRR antenna as half of a slot antenna with the end left open to account for the missing quarter wavelength (otherwise the feed point impedance would skyrocket being a shorted quarter wave stub). Maybe that explains the vertical polarization.
It wasn't the DDRR that I was analyzing the vertical polarization models show, it was the Super Sinner, and later a dipole antenna mounted horizontally in the modeling software. The DDRR will definitely have a vertical component.
The DB
DB, I bumped the thread here because Shadetree was looking for info on the DDRR and there used to be some good links in this thread.
Thanks for your input on this thread.
