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.
Keystone, HDMI, Home Theater and Simple wall plates
Keystone Wall-plates are primarily used in commercial and industrial buildings to cleanly attach telecommunication cables to a junction box, surface mount box, or a mud ring mounted in the drywall of a building, but are Modus Operandi for newly built homes with Structured Wiring installations. Keystone jack inserts are made for coaxial, twisted pair, HDMI and fiber optic port connections that are snapped into the plate at any hole assignment. Made with rigid high quality plastic, the plates come with one to twelve ports. A keystone port is a hole in the wall plate which allows the insertion of a keystone module or other male or female cabling connectors. We have the most common colors of Ivory, Beige and White.
Surface Mount are the Keystone Jacks can be simply added anywhere at anytime exterior to wall or kickboard. With one or two Keystone type ports, you can jack it out with any keystone port available.

5.1 ("five point one") is the common name for six channel surround sound multichannel audio systems. 5.1 is now the most commonly used layout in both commercial cinemas and home theaters. It uses five full bandwidth channels and one low frequency enhancement channel (the "point one"). Dolby Digital, Dolby Pro Logic II, DTS, and SDDS are all commonly 5.1 systems. 5.1 is also the standard surround sound audio component of digital broadcast and music.
All 5.1 systems use the same speaker channels and configuration, having a front left and right, a center channel, and two surround channels.
Blu-ray and Digital cinema both have eight-channel capability which can be used to provide either 5.1 or 7.1 surround sound. 7.1 is an extension of 5.1 that uses four surround zones: two at the sides and two at the back.
7.1 ("seven point one") surround sound is the common name for eight channel surround audio systems. It adds two additional speakers to the more conventional six channel (5.1) audio configuration. 7.1 surround sound positional audio uses the standard front, center, and LFE (bass) speaker configuration. In its most common configuration, 7.1 surround sound includes two speakers positioned to the side and two to the rear. 7.1 surround sound can also refer to 5.1 surround sound configurations with the addition of two front height channels positioned above the front channels or two front wide channels positioned between the front and surround channels.
The Blu-ray Disc and the HD DVD home video formats provide up to 8 channels of lossless DTS-HD Master Audio, Dolby TrueHD or uncompressed LPCM audio at 96 kHz/24-bit. The Sony PlayStation 3 video-game console can output up to 7.1 LPCM through HDMI for both Blu-ray movies and games.
