a three elements Bobtail vertical array, with a three elements reflectors at about 0.18 wavelength separation.
Few with 50 ohms coaxial cable, using a 6 turns RF choke made of RG59U coax cable wound on a small length of 50 mm or
2 inches diameter CPVC pipe....

The vertical elements can be made from aluminum tubing
of about 10 millimeters diameter to make it enjoy the
benefits of a large diameter pipe that provides wider bandwidth...
