What You WILL Need:
1. 33" or Greater Dish
1. Linear LNBF (universal or standard)
1. Mounting location
1. FTA Stb
1. Coaxial Cable
First off we need to make sure you have the right equipment. To get most of the true fta out there (KU Band) you will need a linear lnb and at least a 30" dish. I recommend a larger dish than that though, there are some tp's that a 30" dish won't get.
There are 2 types of linear LNBFs, universal and standard. I recommend you get a standard LNBF, it makes life a little easier.
Ok, so now you have the proper sized dish and a linear LNBF. Lets start out on one of the more popular FTA satellites, which is g10 located at 123w. First thing to do is to make sure all of your antenna settings are correct.
Select "Menu" on your remote control. From there select installation, and then antenna setup. Choose something like G10r/KU and press "OK"
Here is what your settings should read, if they dont adjust them:
LNB type=standard (assuming you have a standard lnbf-if you bought a universal LNBF then select universal 1)
LNB Local-Freq- 10750 for standard, if you have a universal it will be 9750/10600
22 khz = OFF
DiSEqC= what ever port of the diseqc switch that you connected the linear ku LNBF to. If the cable is connected to port 1 then select port 1 here.
Skew- THIS DOES NOT MATTER, SKEW ON LINEAR LNBFS IS ADJUSTED BY TURNING THE LNBF IN THE HOLDER. This setting is for people who are controlling skew on thier BUD with the Pansat 2700.
TP=11800 v 27.657 This is a strong tp that can be used for aiming.
Positioner setting=This is used if you have a motor, if you have a fixed dish you will not use this
Satellite Scan=all
Ok, that is it for the installation screen. Leave this screen up to help you aim your dish.
Now, lets get that dish aimed.
First off you will need the angles to the sat (asimuth and elevation) and you will also need the "skew" for the LNBF.
The below instructions are for a fixed dish, you will NOT set skew on a motorized dish. Motorized dishs skew themselves.
First you will need to set skew. Lets assume your LNBF is set at 0 degrees skew, which means the f connector that the cable screws onto is pointed at the ground. If the calculator tells you that you need a scew of -45 degrees, you will turn the LNBF until the cable connection is pointed at the 3 o'clock position. If the calculator tells you you need +45 degrees of skew, then set the lnbf so the f connector is pointed at the 9 o'clock position. Now your skew is set.
Here is how I aim a fixed dish. First off make sure your pole is perfectly plumb. Then set your elevation according to the scale. You will need to see the TV for the following steps, or have a helper watch the tv and communicate signal changes. Remember you are looking for signal QUALITY not strength.
After you have set the elevation point the dish to the general azimuth of the disired satellite and SLOWLY "pan" the dish. Make movements of no more than a 1/32 of an inch at a time, then wait 5 seconds for the reciever to register signal change and then move it again. If you move the dish more than 90 degrees and still dont get a signal, then adjust elevation up/down and try again. Some of the cheaper dishs have the elevation marks off, this can really mess you up!
A cheap satellite finder such as a sf-95 makes this process MUCH easier.
After you have found g10 than peak the signal by adjusting skew, azimuth and elevation until you get the best signal. Sometimes moving the LNBF in its holder closer to/ away from the dish can help signal quality.
G10 is a fairly weak satellite compared to the DBS sats. A signal quality reading of 80 is perfectly acceptable for the tp we have been using in this example.
A lot of times it is easier to aim for 121 first and then move the dish a little to g10 after you have that satellite nailed.
Good Luck and welcome to the world of true FTA
