"This is a classic way (2-element quarter-cycle phased array) to get 180
degree-only pattern. It`s often used with vertical antennas. I took a
look at Arnold Bailey`s :TV and other receiving antennas" text (written
in 1950) and he shows a similar sort of antenna using two horizontal
half-wave dipoles, connected together via a transmission line
(open-wire) and fed at the center of the rear dipole. Very clean 180
degree-only pattern."
Yes. The directional patterns on pages 477 and 478 are excellent.
This antenna also appears in Bailey`s catalog of antennas on page 521 as
"Half-Wave Antenna and Connected Reflector". Its resistance at center
frequency is 50 ohms where its gain is 4 dBd. Bandwidth is 60% for 3 dB
down.
I wonder why everybody isn`t using this antenna?
