Telescopic and Antenna Mast Wall Brackets 12 inch Standoff Y Style for 1.25 to 3.00 inch OD Mast
3 Star Inc
Made in the USA!
The WM12W Antenna Mast Wall Bracket Set of (2) Double "Y" Style Brackets, One with a Vertical Brace Strut on the Bottom Bracket, with Hardware Included for a 12 inch Standoff Wall Bracket of Light to Medium Duty Antennas on Mast Poles from 5 to 10 feet long and from 1.25 to 3.00 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.
This "Y" Wall Mount Bracket with 3rd Leg Support is Designed for Wall Mount Support of Antenna Masts of all Diameters from 1.25 inch to 3 inches with 12 inches of clearance from the Wall with the added reinforcement of a 3rd leg that goes to transfer the weight load leverage to the wall, but not the weight of a Telescopic Antenna Mast or ANY Mast greater than 10 Feet in Height (Depending on Antenna size!) off of the Ground and on the Wall alone. Use a Ground Plate like EZ32A or GTMBL to mount the Bottom of a Telescopic Antenna Mast from the ground up, with the Wall Bracket maintaining vertical alignment and clearance from the Wall to pass Roof edge. These Mounts do not replace or otherwize reduce the need for proper guying of the Telescopic Antenna Masts. As with all Masts, Guy wire support and Grounding are Critical to Antenna Survival.

After WWII, 75 Ohm cable has been used as the Transmission Line of Choice for TV, Cable TV and Broadband Signals, Distribution Systems large and small, simply because of its plentiful abundance. As the Industry progressed, It seems there were 10 times as many Connectors as there was Coaxial Cable types, each requiring a Proprietary style of Tool to Fashion the connection with. Most Folks We know stick to using the Connector style that they were introduced to, and the Manufacturer, Make and Model that they have invested in via the Compression or Crimp Tool they own. Whereas before, when each manufactured cable type introduced was paired up with a specific Model Connector from one or several different Manufacturers, many have now settled on providing Connectors whose Braid, Shield and Jacket coverage range is broader in scope, encompassing the designed ability to fit many variations of a particular sized cable. Becoming Universal certainly has its advantages... And RG6 is now the minimum size recommended for any HDTV Satellite, Off-Air DTV or Satellite TV Install. So please consider a transitional investment towards the Universal RG6 Compression Connectors and Universal Compression Tools we offer, as the sourcing of those out-dated Connectors becomes more difficult!
