EZ 70W Roof Vent Mount - for Vents 2-1/2" t0 5-1/2"
Made in the USA!
for mounting Antenna and Mast onto Sturdy Roof Vent Pipes from 2.5 to 5.5 inches in Diameter. Then Mount Masts up to 1.75 inches in Diameter to hold your TV or Satellite Antenna. Hardware included. Professional Grade, Sturdy. (Mast not Included)
The Vent Pipe used for this attachment must be of Sturdy Stuff (Steel, Ceramic or Equivalent... NOT PVC or Aluminum Foil!), otherwize you will witness a Whole Lot of Shakin' Goin' On with your TV Antenna and Mast! Great for Antenna Masts from 1 to 1.75 inches in Diameter. 1.25 inch diameter Masts are the Standard for Off Air TV UHF/VHF/FM Antenna. Though most TV antennas can be mounted to 1.75 or even 2.00 inch Diameter Masts. Keep the Mast length as Short as Possible, and limit the Dish Size to 20" or less. If Mounting a Off Air TV Antenna, the size of the Antenna would be limited by the amount of Cantilever achieved to offset the torque generated by wind load (increase the distance between the 2 clamps as antenna size goes up!). The Standard is a 1.66 or 1-5/8 inches Diameter Pipe size in most Universal Mounts for Satellite Dishes. Whether Aftermarket or Service Provider supplied, this mount can accomodate even large Dishes for DirecTV (1 and 3 LNB only, the World Direct International uses 1.75" DIA Mast and the Ka/Ku HD Band uses 2" DIA Mast), Dish Network 500+/1000+, Dish 500 Plus, Dish 1000 Plus, DishPLUS, Dish Network TurboHD 1000.4, Dish 1000.2, Dish Network 1000.4, DishPro, 105 SuperDISH, 121 SuperDISH, EchoStar Technologies Corporation, most FTA Free to Air and DBS Direct Broadcast Satellite Dishes. In addition, it can be used in mounting some smaller PCS, Cellular, Broadband Wireless, Wireless Internet and Two Way Antennas.
There is no substitute of height, clear line-of-site and size does matter... The higher the frequency, the higher the loss... Amplifiers do not give you something that you didn't have already...
The first key to any reception is to get above obstructions that exist between you and your target, as radio frequency reception of any kind (satellite, microwave, Radio and TV) are for the most part "Line-of-Sight" dependant. The fact that some receptions occur without line of sight is due to phenomenon not applicable in this discussion. As you increase your target distance, you increase the territory you must account for in maintaining line-of-sight.
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.
These Mounts are Quality made by Manufacturers with a History in the Field of Proven Success and Longevity. Whether you are planning to Install your Antenna and Mount to the Roof Peak, Gable, Vent Pipe, Chimney or Pitch, Please plan your installation to Minimize the Structural and Asthetic Impact to your House or Building, research and follow all applicable Local Building Codes and annex the appropriate Structural Engineering Assistance when utilizing Non-Penetrating Mounts with Concrete Cinder Block Ballast on any Flat or Pitched Roof.
