Model No: 295XP6
FEATURES:
The 295XP6 is a small sized, computer optimized, cross-polarized antenna. Depending on phasing between the vertical
and horizontal element set, horizontal, vertical, right or left hand circular polarity is available. Electro-mechanical features
include machined components and stainless steel hardware. The rod elements are centered in the boom on UV stabilized
insulators and secured with stainless steel shaft retainer. All connectors are threaded and O-ring sealed to the feed block.
The block’s internal cavity and connections are encapsulated in a silicone gel that seals out moisture and provides a
dielectric strength 3.7 times greater than air for improved power handling capability. Balun connectors are triple-sealed to
the coax and nut-sealed at the block.
SPECIFICATIONS:
*Subtract 2.14 from dBi for dBd

295XP6 ASSEMBLY MANUAL
TOOLS REQUIRED FOR ASSEMBLY: 1/2” and 7/16” end wrenches or sockets, pliers, measuring tape.
HORIZONTAL ELEMENT ASSEMBLY
1. Separate the 3/16” ROD elements by length into two identical sets, “H” and “V”. Position the “H” element set along the
boom by length and spacing as shown the DIMENSION sheet. Start with the REFLECTOR (longest) element. Balance it
on your finger to roughly determine it’s center point and push on a black button insulator on one side of the rod to about
1” off of center. Next push the REFLECTOR element through the appropriate holes in the boom and allow to protrude
about 1” on the opposite side. Now install the second button, snugging it up to the boom. DO NOT CENTER the element
at this time and DO NOT INSTALL any of the stainless steel SHAFT RETAINERS yet. It is easier to do it after all the
horizontal elements are installed in the boom.
2. Repeat (1) for the installation of the remaining two HORIZONTAL “H” SET of 3/16” ELEMENTS.
3. Now accurately center the elements using a tape measure. EQUALIZE the amount of rod sticking out on each side of the
boom. 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 and 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 first retainer too far, or, grab the opposite side of
the element 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). Repeat for the opposite side. Continue installing retainers until all elements are locked in place.
5. Mount the HORIZONTAL DRIVEN ELEMENT BLOCK / 1/4” ROD ASSEMBLY to the TOP of the boom as pictured on the
DIMENSION SHEET using a 8-32 x 1-1/4” screw and lockwasher. Orient the block with the two balun connectors facing
towards the FRONT of the antenna and the feed connector towards the REAR.

6. Install the 8-32 x 1/4” set screws (internal Allen head - tool supplied) into the SHORTING BARS. Slide the bars on the 1/4”
Driven Element Block Rods and the 3/8” driven element rods. Position the shorting bars to the specified dimension on the
DIMENSION SEET, measured BETWEEN THE OUTER FACE OF THE DRIVEN ELEMENT BLOCK AND THE INNER
FACE OF THE SHORTING BAR. Now tighten the set screws.
VERTICAL ELEMENT ASSEMBLY
1. Repeat steps #1 through #6 for the Vertical elements, using the DIMENSION SHEET as your guide to the lengths and
spacings. Mount the VERTICAL driven element block to the LEFT side of the boom (as viewed from the rear) with the
two balun connectors facing forward (see Dimension Sheet).
COMPLETING ANTENNA ASSEMBLY
1. Before installing the Baluns, thread 3/8” seal nuts fully onto all “F” connectors on both the horizontal and vertical driven
element blocks, with the black Neoprene face of the nuts facing out. Attach Baluns to the Blocks as shown on the figure
on the last page. Tighten the connectors gently using a 7/16” end wrench. Once the connectors are tight, back the seal
nuts out and finger-tighten firmly up against the face of the connectors (or tighten gently with 1/2” end wrench). A lot of
torque is unnecessary. Form baluns close to the boom and secure with a nylon cable tie. Also secure feed coax with
cable ties. Ties should be snug but not crushing or kinking the coax.
2. Attach the 3 x 4 x .125” BOOM TO MAST PLATE about 1” from the rear of the antenna with two 1” U-Bolts. On the
opposite side of the plate loosely install the two sets of 2” cradles with 5/16-18 x 3” bolts, lock washer and locknuts.
3. Attach feedlines and fasten to the boom with cable ties. To provide stress relief use a nylon tie to secure feed coax near
connector on each block. Route feedlines to rear of boom and secure again.
