For the
Vietnamese channels you should get a 36" or larger dish with two LNBs; you need a
DiSEqC switch for the two LNBs. Align the dish using LNB1 to
IA5 and tighten it down. This will get you VTV4 from Vietnam. Feed LNB1 into the "A" port (#1) on the DiSEqC switch. Then connect LNB2 and hold it beside LNB1 (on the right side when facing the dish). Move it around slowly until you lock onto AMC4 (for VPTV channel); you must use tie wraps and silicone caulking to attach LNB2 to LNB1. LNB2 then feeds into the "B" port (#2) of the DiSEqC switch. Then configure your receiver accordingly (ie: IA5 on port 1 and AMC4 on port 2).
