DSE3318LYRMK Rev 3/21
ASSEMBLY TIPS:
The boom diameter is 1 inch, and it is drilled for 4-40 hardware (no. 33 drill bit). The driven
element hole is enlarged to 5/16 inch. All elements are 0.032-inch-thick and 0.375 inch wide.
Note that the element spacing from D7 on is 5.115 inches.
The loops and driven element are
preformed to their proper shape. The connector/coax assembly is soldered to the driven element
as shown below. Form the coax cable using your thumb as a guide to bend the coax and bracket
so that the bracket mounting hole is aligned at the R1 drilled hole in the boom. (See drawing
below.) Be careful with the .141" coax. It can be crimped if not supported by your thumb! Attach
the coax bracket with the hardware from R1. For the best match, the driven element should be
approximately 4 inches high: this makes it wider than it is tall. This shape can be adjusted for best
match. The space between the loop ends should be 3/8" (9.5mm). This spacing will prevent water
from "beading up" there during wet weather.
The design of this antenna is based on work done
by G3JVL.
