The invention relates to satellite dishes.
When installing a small satellite dish (e.g., Ku band) of the type used by DirecTV™, DishNetwork™, Sky™, Bell ExpressVu™, Starchoice™, or other satellite programming provider, the most difficult part of the installation is getting a lock on the satellite. Such dishes are manufactured, for example, by ChannelMaster™ of Smithfield, N.C. One of the items important for success, in addition to the need for a clear line of sight, is the need to make sure that the mast is level. If the mast is not level, a seemingly small error is magnified when rotating the dish to try to find a satellite that is miles away in the sky.
While a level can be used, and moved to various positions around the top of the mast, the masts are often not completely cylindrical so it can be hard to line up a level around the mast. Additionally, the mast may be installed relatively high up on a house, making manipulation and viewing of a level difficult. Still further, it may be difficult to adjust a satellite dish and hold a level at the same time. Holding and adjusting a dish does not leave any hands free.
The invention provides a satellite mast including a level.
In some aspects of the invention, a mast includes first and second levels supported by a mast member, viewable from an open end of the mast. The levels are stacked one on top of the other, with the first level oriented generally normal to the second level, generally defining a plus sign when viewed from the open end, so that the open end of the mast can be made level both from left to right and from front to back by looking into the open end of the mast.
In some aspects of the invention, a mast assembly is provided including a mast member and a level mounted interior of the mast member but visible from the side of the mast member through an aperture in the mast. This allows the dish mount to slide on to the mast without encountering resistance from the level. Additionally, the level can be viewed without having to access and look into the top of the mast.
In some aspects of the invention, a mast assembly is provided including a mast member and a level supported by the mast member, the level including at least one surface generally flush with the exterior of the mast member, wherein the level does not impede sliding movement of a dish mount onto or off of the mast.
In some aspects of the invention, a mast assembly is provided including a mast member and at least two levels supported by the mast member, one arranged in a first plane, and arranged to be viewed at a front of the mast and viewable from the front of the mast, and another, arranged generally normal to the first level, arranged in the first plane, and viewable from the side of the mast. The first level can be viewed from the front of the mast and the second level can be viewed at the side of the mast.
In some aspects of the invention, the level includes fluid that will not freeze or boil at temperatures the dish may encounter. Different specification levels/dishes may be used in different areas. For example, one could use fluid that will not freeze at above −50 degrees nor boil below +50 degrees Celsius for in extreme climate areas; or, for example, fluid will not freeze at above −40 degrees nor boil below +40 degrees in other areas.
In some aspects of the invention, a satellite dish assembly is provided including a mast assembly having a mast member and a level supported by the mast member, viewable from outside the mast member, a dish mount slidably receivable on the mast member, a satellite dish, including a concave signal focusing surface, supported by the dish mount, and an LNBF supported by at least one of the dish mount and the dish arranged relative to the dish to collect the focused signal.
In some aspects of the invention, the mast member has apertures therethrough and the level is supported by the mast members using the apertures.
Preferred embodiments of the invention are described below with reference to the following accompanying drawings.
The dish assembly further includes a dish mount or support assembly 14. The support assembly 14 includes a dish bracket 16 having a plurality of apertures 18 aligned with apertures 20 through the dish member 12 for fastening of the dish member 12 to the support assembly with fasteners 22, 23. The dish bracket 16 may have, for example, a shape complementary to the shape of the back of the dish member 12 for supporting the dish member 12.
The support assembly 14 further includes a support arm 24 for supporting one or more LNBFs 26 in signal collecting relation relative to the front of the dish member 12. The LNBF 26 and support arm 24 respectively have aligned apertures 28 and 30 using which the LNBF is secured to the support arm 24 in a proper position using a fastener 32, 33 such as a nut and bolt, screw or screws, or other fastener. The LNBF(s) 26 may have a multi-switch built in to allow switching between multiple satellites in the dish member 12 is of the type that can collect signals from two adjacent satellites or a multi-switch may be provided in a coax line downstream of the LNBF.
The support assembly 14 further includes a mast clamp 34 including a clamp member 36, typically having an inner cylindrical surface, which receives an upper portion or mast member 40 of mast 42 up to pivot bolt 44. The mast clamp 34 also includes spaced apart pivot arms 45 on either side of the clamp member 36. The dish bracket 16 is pivotable relative to the clamp area 36 about pivot bolt 44 to set dish elevation angle. The mast clamp 34 is pivotable about the top end 40 of the mast 42.
