PRO-67-B V.2.S
PLACEMENT OF PHASING LINES ON DRIVEN ELEMENTS
< > Note: The BEND IN THE PHASING LINES GO IN TOWARD EACH OTHER OVER THE BOOM. This will ensure that the lines
are clear of the mast, however the phasing line closest to the mast will run near the mast.
< > Lift the screws on the inner insulator blocks first on the front driven element (Note the BROWN color on the phasing lines) and
place the color coded end of the phasing line on top of the element and secure with the lock washer and 10/32 screw. Refer to
drawing.
< > Repeat this procedure to the opposite side of the FDE.
< > Repeat this for the back driven element.
< > Connect phasing line to BDE as was done on FDE.
ASSEMBLY OF SINGLE TRAPPED ELEMENTS
< > Assembly of the trap reflector, color coded YELLOW.
< > Insert a YELLOW coded element section (Part 38) on each end of the center section of (Part 39) and align the large holes,
KEEPING end element holes for next section pointing down.
CAUTIONS
< > In an attempt to keep the weight of the antenna down to a minimum, we are using a .035 wall on the small, single end tips. In
their area of use, they are as strong as a heavier-walled piece. However, WHEN SECURING WITH THE #8 STAINLESS SHEET
METAL SCREW, DON’T OVER TIGHTEN! Seat the screw flush with the tubing and stop.
< > CAUTION: Trap Assemblies are color coded on one end of the trap tubing.
THIS COLOR-CODE SHOULD ALWAYS GO TOWARD THE BOOM. INSERT TOWARD THE CENTER. REVERSAL OF THE
TRAPS WILL CAUSE HIGH S.W.R. AND OTHER MALFUNCTIONS.
< > Mark the color-coded ends of the traps by placing masking tape on the metal trap cover and note the side and color on the trap.
This will solve any problems if the color code comes off when sanding or placing the penatrox on the trap tubing. THE TRAPS CAN
GO INTO THE 7/8" CONNECTING PIECE EITHER WAY.
< > The various pieces of tubing used on the antenna elements are also color coded on one end. This end always goes in toward
the boom. Secure with #8 Sheet metal screw.
< > NOTE: Select the correct END TIP SETTING if a choice is given.
