Thanks for purchasing the Ricks Satellite BSC621 C/Ku LNBF. 

This unit is not associated with the DMSI model BSC621, but DMSI has given us permission to use the same part number. This is an inexpensive C/Ku LNBF that can be used as a combination Feed Horn and LNBF to receive both C and Ku band satellite signals.  While it will NOT yield as good of results as a Chaparral Feed Horn with some very good Norsat LNB's, it still generally works good and is less than 1/5th of the cost of the before mentioned combo.  

We do not sell this unit as a High Quality unit, but as a good working unit that when used on a well tuned dish will still receive quite a few signals, depending on what satellite/s you are aiming at.  You will need to do your research to make sure you understand things like Focal Depth and Polarization angles before purchasing or you may well not be able to make it work.  This is for the more advanced user to install, but priced for where someone new to the hobby can afford and still try and learn how to use.  It performs best when used on a 10' or larger satellite dish, but it can be used on smaller dishes, but with much less signals received.  We cannot guarantee what you will be able to receive when using this part, as there are many variables involved, including Dish Size, Dish Condition, Dish Aiming, Cable Condition, etc.  You need to study to understand all of the variables to what makes a good satellite reception system and be willing to accept that results will vary on individuals systems based on the above. 

The C-Band LNBF has an LO of 5150 and the Ku-Band LNBF has an LO of 9750/10600.  It has 2 separate outlets.  One for each band.  It does Not have a built in Switch to pick between the 2.  You can use either a DiSEqC Switch or a 22KHz switch if you want to combine the 2 cables at the dish and then run just 1 cable inside.  This works best with shorter cable runs of 100' or less and you have to weather proof the switch or it will fail.  I prefer to run 2 cables and then place my switches inside, completely out of the weather.  Remember to be sure and power down completely, any connected receivers / equipment that is supplying voltage before connecting or disconnecting any switches or they may be damaged. 

If putting this C/Ku LNBF on an existing dish, be sure and measure the focal depth of the current feed horn and set this one to the same.  The LNBF throat does NOT have any markings like Chaparral Feed Horns.  If you do not have an existing feed horn you are replacing to compare to, then here is a formula for calculating your focal depth (f = D² / 16d ).  Or you can experiment by moving the throat in and out of the feed horn to get your best signal.  You may also want to read the information at this link: http://www.analyzemath.com/parabola/parabola_focus.html

Since the Horizontal and Vertical C and Ku band probes are in a fixed position, you have to rotate the feed horn in the scalar ring to the proper angle to get the maximum signal.  If using this Ricks Satellite BSC621 C/Ku LNBF on a Polar Mount or Motorized dish, then please use the following settings when setting the Polarization Angle. 

The Top F Connector is for Ku Band.  The Lower F Connector towards the middle of the feed horn and on one side is for C Band.  Look at the Top of the C/Ku LNBF.  There is a Small Arrow on the Top of the assembly.  With your dish pointed to True South (be sure and figure in your Magnetic Offset), Point the Arrow to 9:00.  Slide the Feed Horn into the scalar ring.  The center hole in the scalar ring is larger than the Feed Horn.  We wish it was a tighter fit, but we have yet to be able to get them to manufacturer one that is just a little bit larger than the throat.  However, there are 3 threaded holes in 3 different locations on the throat of the scalar ring and the screws to be used are included with the LNBF and you will need to use those 3 screws to CENTER the Feed Horn in the scalar ring.  You can use a tape measure and measure from the outside of the dish to the outer portion of the throat of the feed horn in at least 3 different locations, to make for sure that the feed horn is centered.  A Laser pointer can also be used by placing in the middle of the feed horn throat and aiming towards the dish.  There are expensive Dish Laser tools available or some people make up their own which can be more difficult.  However you do it, it is CRITICAL that the feed horn is centered in the scalar ring to obtain the best signal that you can get that is being reflected from the surface of the dish. 

Once you have the Feed Horn installed then either using a Signal Meter like the really Neat and Easy to Use SH200HD Sat Hero for 149.00 or just hooking up to your satellite receiver and watching the TV screen, you can now do your fine tuning adjustments to either find and bring in a signal or if you already have a signal, then Peak the Feed Horn by rotating it either clockwise or counter clockwise to get your highest quality and also by moving the feed horn closer or further away from the dish.  You may also have to move your dish east or west and adjust your elevation up and down to make for sure you are properly aimed at a satellite. 

Everything is Critical to get a good signal.  The Satellite signals are quite strong, but they are traveling over 22,500 miles down and if you off by even a 1/16 of an inch, that is a lot and can be the difference between having good signals or having nothing at all. 

When using on a Fixed Dish aimed at one satellite, you will need to go to http://www.dishpointer.com and pick the satellite name you are aiming at and put in your location and determine what your skew is.  Then starting with the same basic steps as outlined above, then rotate the feed horn to what ever your skew setting is and then proceed with doing your fine tuning. 

We try and do all we can to support our customers and we want you to get what you want out of any part that you buy.  But please keep in mind, that there are Many Variables Involved in being able to install and aim in your own satellite equipment.  We have many very good Forum Members in our Ricks Satellite Wildfeed and Backhaul Forum that will also be willing to help.  We do our best to keep things friendly or productive in the forum, as we want anyone to be able to read and ask questions to help us all learn more about the Hobby. 

Thanks again for purchasing this Ricks Satellite BSC621!
