Just sharing more information!
The scenario could be a little different in the next few months. Right now there are two satellites at the 61.5 location. Rainbow1 (the one they acquired from Voom with very low signal strength in Puerto Rico) and the EchoStar-III (with better signal strength overall, but with transponder troubles).
Rainbow1:
"The spacecraft features 24 MHz Ku-band high power transponders with a combination of 135 watt and 65 watt power amplifiers."

EchoStar-III:
"Power converters: Certain of the electric power converters (EPCs) on EchoStar III are operating at higher than expected temperatures. The high EPC temperatures may require certain transponders on EchoStar III to be turned off for several weeks during summer and winter solstice seasons to avoid overheating.
As a result, EchoStar III is operated at 120 watts per channel, which is typical for 42-cm dish service to the continental United States. If the satellite were operated at a "super high" 230 watts per channel, approximately half of its 16 channel capacity would be unavailable during solstice seasons by the end of the satellite's planned life."

Dish is replacing by March/2008 (launch) and will be operational on May/2008 EchoStar-III with AMC-14:
"which consists of thirty-two 24 MHz Ku-band transponders. In addition, the spacecraft carries a demonstration phased array antenna that enables coverage shaping while the satellite is in orbit."

Press Release
If the "coverage shaping" technology works and benefit Puerto Rico, we could get better signal strength starting in May (that could mean 4' maybe or 5' dish). We have to try it when is up in the sky. Also, Dish has to move the HD channels from Rainbow1 to the new AMC-14 for Puerto Rico to benefit.
The only way to know for sure is to wait until May.
