The mast should work fine... however provided your geographical position, it may not be adequate as the 129 sat rides at a lower elevetion as opposed to the 119&110 sats. The 129 is a lowered powered sat also, a good signal strength should be between 70 and 80,
Depending if you are using an old reciever(i.e. legacy equitment,3900 series, ect.)
you would need a dish pro adapter for the 129 sat, also a 3/4 dish pro switch (i.e. three sat inputs, four receiver outputs...) a dual LNB and a Twin LNB....
If you have a newer receiver,,,-pretty much anything with three digits(ex. 301,311,211,ect..) you will have to use Pro Plus equitment.... Confused yet?
Ok take your Dual LNB place it in the 119 slot of the dish 1000,,, buy a Satbuddy, or similar signal meter,,,check your elevation/azumith on the receiver, make sure your dish is set according to your zip code... peak in until the 119 is maxed... move dual LNB to 129 position on dish 1000, secure with screw.. position dish until 129 sat is at highest strength....you know what... read the damn manual.. i'm finished.. it tells you right their everything you need to know
