ROHN WM18D Antenna Wall Mount 18 inch Y Style Double Brackets for 1.25 to 2.75" OD Mast
ROHN
Made in the USA!
The ROHN WM18D is a Hot Dip Galvanized 14 Gauge Steel Heavy Duty Bracket Set of (2) Double "Y" Style Brackets with Anti-Twist Feature, One with a Vertical Brace Strut on the Bottom Bracket, with Hardware Included for an 18 inch Standoff Wall Support of Light to Medium Duty Antennas on Mast Poles from 5 to 10 feet long and from 1.25 to 2.75 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 TV Passives
Here you can find passives for use between the satellite dish and your receiver(s) that will complete your system and bring the parts and pieces of the whole installation together. When you add a second source of Signal to Feed thru your System such as off-Air TV antennas, Cable TV or a Broadband Internet connection, these components now become a Necessity! With the Right Selection of Parts, You can route, Mix and Distribute almost Any Combination of Wide-band Signals to the location you need them. Then, once there, you can separate and Provide the Inputs necessary for the Appropriate End-Use Equipment.
Signal Gains & Losses
Do not forget to account for gains and/or losses throughout your system of distribution, starting with the Signal Origin (LNB) and Terminating at the Receivers. The Starting Signal Level and Amplifier Gains should Equal the Line (Drop) and Passive Losses in addition to the proper Signal Levels above Receiver Input Threshold to Optimize Signal to Noise Ratios, Picture Quality and Performance.
Splitting a Satellite Signal
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" category for selection.
Sending Voltage Back
There is also the issue of supplying Voltage back to the LNB(F), this may be addressed more resolutely with the installation of a Power Supply and Power Inserter made just for this purpose. Review the "DC Power Inserter" category for these items.
Signal Diplexers
Most Signal Diplexer Examples Use Scenarios requiring two (2) of these devices to properly Mix and then Un-Mix the signal feeds to the Appropriate Devices in question.
Grounding Your System
Commensurate with Satellite TV Antenna and Splitter Installation, you want to Ground your Coaxial Cable System Outside before bringing the RG-6 Cable Inside. This way, Lightning Strikes and Power Surges have an opportunity to arrest before reaching your TV and Entertainment Electronics. The Integral Grounding Block designed onto most Outdoor Use Compatible RF Signal Splitter we sell will effectively convey this unwanted Electrical Energy to a Ground Rod via a Copper Ground Wire that you Install (not included). Also Available are Dual F Port Grounding Blocks specific for this purpose and Frequency rang.
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.
