EZ 70W Antenna Mast Bracket for Large Vent Pipe 2.5" - 5.5" OD Mount
3 Star Inc
Made in the USA!
The EZ 70W Roof Vent Pipe Antenna Mast Mounting Bracket is for Mounting Satellite Dish and Off Air TV Antenna to Larger Vent Pipes from 2.5" to 5.5" inches in Outside Diameter. Mast Mount with Hardware (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.
Satellite diplexers are used outside to combine and then separate two separate RF Bands: The 950 to 2150 MHz from the Satellite LNB(F) and the Cable TV or Antenna TV channels. The First would combine these two bands for conveyance via a single RG-6 coaxial cable on one side, and then a second satellite diplexer is used on the other to separate the combined signals for connection to separate these Bands for Input to receivers and the like. Some Satellite Receivers will have Diplexer/Separators built in (Confer with your Installation Guide or Spec. Sheet). Satellite diplexers eliminate the need for extra wiring thereby reducing the cost of labor and installation materials necessary to run two separate coaxial cable drops to carry each signal source independently.
If you have Off-Air Antenna TV Signals mixed with the Satellite Signals, you will need "Wideband" Splitters that have a minimum start frequency of 50 MHz and again, pass up to 2050 or 2150 MHz. (depending on Service). Those Splitters that have a Start Frequency of below 40 MHz are used for carriage of both Satellite and Cable TV with Return Band two way services like H-Speed Internet Broadband Modems and Set Top Pay-per View TV Converters.
Conversely, regular Cable TV Antenna Signal Splitters have a start Frequency of 5, 40 or 50 MHz. and a Stop Frequency of 900 or 1000 MHz (1 GHz). You could utilize any of those Splitters for distribution use of the Output Signals of the Satellite Receivers to other TV Sets.
When Supplementing your Satellite TV Antenna Installation with additional Components, consider Grounding. Dual F Port Grounding Blocks specific for Grounding un-wanted Electrical Surges and Strikes away from the LNB(F), Satellite TV Receiver and TV Set(s) are available. See the "Drop Ground Blocks" Category. Consult your Local Building Code and NEC for guidance to Properly Grounding your HD TV Antenna, Satellite TV, Cable TV, WI-FI, Wireless Internet, Business Band, CB or Amateur Radio Antenna Installation.
