ROHN DDM150 Tower DBS Dish Antenna 1.50 inch Mount
for Mounting DBS Satellite Dish Antenna on 1.5 inch DIA, 3 foot long Side Arm Assembly of the ROHN 25G Tower. Bolts to 2 Straight Rails of a 25G tower Section. Antenna Support Assembly includes support brackets, clamps, and mounting pipe. Mounting Pipe Sizes are associated with these part numbers and Descriptions:
DDM150 - 1.50 inch O.D. x 3 Foot Pipe
DDM166 - 1.66 inch O.D. x 3 Foot Pipe
DDM238 - 2.375 inch O.D. x 3 Foot Pipe
The Installation of a ROHN TA25 Tower Torque Arm Stabilizer Assembly Anti-twist device located in the area of the Antennas may be advantageous. The 25G Tower can be used guyed, self-supporting or bracketed configurations according to specifications in the ROHN Tower catalog. Consult ROHN Catalog Links at Footer Section below for ROHN 25G Tower Details.
ROHN DDM150 is a Pre-Galvanized Mounting Pipe Version of this DBS (Direct Broadcast Satellite) Side Arm Antenna Mounting Assembly for the ROHN 25G Tower. Depending on the Type of ROHN 25G Tower Installation and Height that you have, an Anti-Twist Guying Mount like the ROHN TA25 may reduce Satellite Signal loss due to Sway and Wind Load Flexing. The ROHN KY2068A15 is a Hot Dip Galvanized, Heavier Version of this Item. American Made... Buy ROHN, Buy American.
It is Important to choose an Antenna Mount and Wall Mounting Location with a Picture of the Finished Antenna Installation in Mind. Be Sure to First select a location that lends itself to applying a Vertical, Cantilevered, Twisting Load without Compromising the Integrity of the Wall Material you affix to. Most Modern Exterior Decorative Wall Finishes most often do not have the Strength to Hold the Weight and Pressure of a Large TV Antenna under Wind Load without fail. Beams and Studs within the Wall are an Absolute Must to Locate when the Wall Composition is anything other than Solid wood or Concrete. Attach to these Strength Members. Further, Think about what's underneath the Wall exterior. Is it stronger, will it yield to Pressure over time as well? Sandwich additional Material (wood or steel) to the backside or both sides of the wall at the points where the mount attaches, as to distribute the load on relatively weak wall materials and to dampen vibration from Wind. Weather Proof the Installation to Maintain the Integrity of your Home. Next consider the Location over a Lifetime of Adjustments, does it lend itself to modifications in Height or Direction? Larger Antennas increase the surface area presented to air movement, Hence, Wind-load does increase. As the length of the mast increases from Its last attached point on the structure, the torque applied also increases with Weight and Wind-Load, requiring a more substantive attachment and Load-Bearing material. Keep the Distance Minimal from the Antenna to the TV's and Equipment you feed, as to minimize loss and the need for Amplification. Further, the NEC (National Electrical Code partly defines a good Ground connection as being as short as possible, you must affix a connection to a good Earth Ground prior to Premise entry or Bond to an existing one.
