Universal Roof Antenna Mast Mount for Peak and Pitched Installations | ROHN URM

What tall building and air traffic exist in this corridor, no one can account for. Aircraft are very good at messing up reception for a number of reasons, even when flying way above the path, again removed for clarity in this discussion. Height, is therefore key in optimizing your ability to capture the best line-of-sight possible to your target. The Roof of any Building of Home provides a Logical Platform of Height in which Line-of-Sight is more likely to occur, or from which, more height can easily be obtained.

Roof Base Mounts for Antenna Mast Poles are not centered upon a stake or fixated solely by the Down Guy Wires (keeping in mind there is no wall to bracket to) and therefore require a mechanical connection through the shingles, tiles, etc., past the vapor and weatherproof barriers to the structural load-bearing components that lay beneath. This attachment is usually made by means of lag screws and the watertight barrier is sealed with a pitch-pad between the base and shingle in which the lag screw will perforate and fixate.
Most Roof Mounts for Antenna Mast Poles these days are flexible enough to accommodate mounting on a Flat, Pitched or Peaked Roof location. Imagine a cup with two double jointed hinged feet with one on each side and you get the idea. This allows for the Antenna, Antenna Mast and Down Guy Wires to all be lowered and raised together even after the base mount being secured to the roof. The Universal style Cups may actually be a clam with two pieces squeezing the bottom of the mast pole via screws that draw to two pieces together. The cup style may come in a variety of diameters to accommodate a specific range of mast sizes then secured by set screws. It is important to note that as in the case of the Ground Base Mounts, No Base is "Freestanding" or "Self-Supporting" and rely on a combination of brackets and down guy wires to keep the mast pole in place and the antenna on target. The down guy wires then have to attach to another structural load-bearing component of the roof at several locations by means of round-eye lags, bolts and screws. The Pattern of down guys is 3 or 4 way. 3 way mostly used on the ground with 4 way mostly used on home roofs with a guy going to each corner.

It is Important to choose a Mount and Mounting Location with a Picture of the Finished Installation in Mind. Be Sure to First select a location that lends itself to applying a Load without Compromising the Integrity of the Material you affix to. Most Decorative Finishes most often do not have the Strength to Hold a Weight or Pressure without fail. Further, Think about what's underneath the exterior. Is it stronger, or will it yield to Pressure over time also? 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 in cantilever 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.
