167XP22 ASSEMBLY MANUAL
2. Install the 3/16” DRIVEN ELEMENT ROD as you did the reflector and then the DIRECTOR ELEMENTS.
3. Now accurately center the elements using a tape measure. EQUALIZE the amount of rod sticking out on each
side of the boom within 1/16” or better. Once you have all the elements centered, sight down the element tips from
the rear comparing each side. Look for any obvious discrepancies and correct if found.
4. Begin installing the stainless SHAFT RETAINERS. Use thumb index finger to hold a retainer over end of the 3/8”
x 3” push tube (keeper dished into tube). Hold the element firmly and start the retainer onto the rod by applying
pressure with the push tube. Push the retainer until up tight against the button insulator (locking pliers, clamped up
against opposite button insulator will help maintain center reference and keep you from pushing the tube off center.
Alternately, grab the opposite side of the element near the boom and pull it hard sideways to the boom to preload
and increase the friction of the element on the button insulators while pushing the retainer. Do all the retainers on
one side first, DOUBLE CHECK CENTERING and then do the other side. Continue installing retainers until all
HORIZONTAL elements are locked in place.
5. Mount the HORIZONTAL DRIVEN ELEMENT BLOCK / 1/4” ROD ASSEMBLY to the TOP of the boom using a
8-32 x 1-3/4” screw. Orient the block with the two balun connectors facing forward, “N” connector to the rear.
6. Install the 8-32 x 1/4” set screws (internal Allen head - tool supplied) into the SHORTING BARS. Slide the bars
onto the element rods and
Position the Shorting Bars per the DIMENSION SHEET
. Align the rods parallel and
the bars with each other and tighten the set screws moderately at this time to keep the bars in place. Final tightening
should be done after each antenna has been checked out electrically with an antenna analyzer or SWR bridge.
ASSEMBLING VERTICAL ELEMENTS
7. Repeat steps #1 through #6 for the Vertical elements, using the Dimension Sheet as your guide to lengths and
spacing. Note the vertical driven element block HAS A RIGHT ANGLE “N’ CONNECTOR and should be mounted on
the RIGHT side of the boom when the rear driven block is up (LOOKING FORM THE REAR). The two connectors
for the balun face the rear.
COMPLETING ANTENNA
1. Install the seal nuts on each female balun connector with the black neoprene seal out. Then install a balun to
each driven element block connector. Form the balun coax away from the block in a single loop. Form closely to the
boom and secure near the loop end with a nylon tie. Depending on the model, a balun may loop around an element
in the opposite polarity. This is normal. Tighten the connectors gently with a 7/16” end wrench and then run the seal
nuts up against the face of each male cable connector. Gently tighten about 3/4 turn beyond finger tight with a 1/2”
end wrench.
OVERHEAD GUY SUPPORT ASSEMBLY:
1. Mount the small 3” x 4” plate where the second boom section just starts. Use 1-1/2” U-bolts, nuts and
lockwashers. Add the two 1” U-bolts loosely and then insert the fiberglass mast section with the large end into the
U-bolts. Align the top hole with the boom and tighten the nuts on the 1” U-bolts.
2. Tie one end of the 5/32 dacron guy rope to the front eyebolt. Thread the other end through the fiberglass mast top
hole and back to the rear of the boom. Open up the 1/4” turnbuckle until just one thread shows on each end inside
the body. Hook the turnbuckle into the rear eyebolt and attach the Dacron rope securely. Adjust the turnbuckle until
the boom is straight.
NOTE:
The 167XP22 is a cross polarized antenna that creates fields in both H and V planes. By combining the
HORIZONTAL AND THE VERTICAL elements through equal lengths of 50 Ohm feed line and into an M2 2 port
power divider, RIGHT HAND CIRCULAR POLARITY is created. By making one of the feed lines longer by 1/2
wavelength, LEFT HAND CIRCULAR POLARITY is created. LEFT HAND CIRCULAR can also be done at the time
of assembly by mounting the REAR DRIVEN ELEMENT on the other side of the boom. Always mount this antenna
at the rear as shown or on a nonconductive support mas and bring the feedlines off the rear.
