The 3S-W24 Antenna Mast Wall Mount Set of (2) Double "Y" Style Brackets, One with a Vertical Brace Strut on the Bottom Bracket, with Hardware Included for a 24 inch Standoff Wall Support of Light to Medium Duty Antennas on Mast Poles from 5 to 10 feet long and from 1.00 to 1.75 inches in Outside Diameter for Off-air and OTA TV, UHF/VHF Radio, Remote Telemetry Control and Monitoring Stations, Cellular Date Gateways, WiFi, Wireless Internet, Receivers, Boosters and Repeaters.(Mast Not Included)
These mast mountings are typical and generally require the cantilever distance between the mounts be one quarter (1/4) to one third (1/3) of the mast length depending on Wind Load, starting from the bottom with 2 foot between brackets being a minimum distance. All Masts greater than ten feet in length, and/or 2 inches or greater in O.D. should be based upon and from the ground in rising up to the desired height.
Also for Telescopic Mast Poles comprised of 1.25", 1.50", 1.75", 2.00" and 2.25" Tubes nested together and then extended, these wall mounts can supplement structural support but are not designed to take the place of a Base in Supporting the weight of the Mast off the ground or guying. Be sure and check that the Tube segments you wish to wall mount will fit within the Outside Diameter Window specified that the Brackets will accommodate. Set screw installation may require some field drilling.
Manufacturers recommend that ALL masts above 10 feet from their uppermost support be Guyed
With more height in your installation, Grounding/Bonding is a recommended consideration.
Satellite Splitters Typically Pass from 950 to 2050 or 2150 MHz. and are used between the LNB (LNBF) and the Input of the Satellite Receivers. In this manner a Satellite Signal Feed from the Dish can be "Split" to feed multiple Receiver Units. Low Voltage is Present in this link between the LNB and Receiver and should be maintained and respected. With a 2 Receiver Setup, Voltage to the LNB typically would only be required from one or either of the Receivers. Some Splitters (HOLLAND) have diodes that eliminate the back-feeding of voltage back and forth between the Receivers, otherwise you may have to disable the Voltage eminating out through the "Input" port of one of the Receivers (this function is usually switchable for this purpose). With Multiple Receiver feeds in a "Head-End" scenario where receivers are dedicated to specific channels for mixing and carriage onto a Cable TV or Satellite Master Antenna System, the question of feeding Voltage back to the LNB is addressed with a separate power inserter for this purpose.
If you have Off-Air Antenna TV Signals mixed with the Satellite Signals, you will need "Wideband" Splitters that have a minmum 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 Hi-Speed Internet Broadband Modems and Set Top Pay-per ViewTV 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.
These 3-Way Satellite Splitters are typically the Part you would use to take One (1) LNB(F) Feed and "Split" it into Three (3) in order to present Signal to 3 Independant Receivers. Please be Sure to Select the Appropriate Device not just By Manufacturer and Price. But Rather, Consider the Specifics of Bandwidth, Packaging (Indoor vs. Outdoor), Insertion Loss, Powering Requirements Up/Down-Stream and the Overall Needs of the Final System You Wish to Create.
When Splitting the High Frequencies of Satellite TV Services to feed multiple Receivers, the Loss associated with the splitter may need to be compensated for with the use of an In-Line Satellite Drop Amplifier specific to this purpose and Frequency Range. Consider the need and review the "Satellite TV Amplifier" section for selection.
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.
