Prague - Czechs that oppose the US radar being stationed in Brdy area of the Czech Republic still constitute a majority.
While roughly two thirds are against the project, only less than one quarter expressed their approval of the radar.
These are the freshest data produced by the Public Opinion Research Center (CVVM) that is monitoring the public stance on the issue since 2006.
The CVVM made two surveys, in March and in April, speaking with more than one thousand people older than 15 years of age on each occasion.
In March, 65 percent were against the radar base, with 28 in favor. In April, 63 percent were against the project, 29 favored it.
Stable results since 2006
"Since 2006, results show stable dominance of the opposition that has between 60 and 70 percent," explained Jan Červenka from the CVVM.
So far, there have never been more than 30 percent in favor of the plan.
"However, since the end of 2007, the number of those opposing the radar has slightly decreased," added Červenka.
Supporters of the Civic Democratic Party (ODS) tend to have the most favorable opinion.
Seven in ten want referendum
Voters of the other parties - Christian Democrats (KDU-ČSL), Greens, Social Democrats (ČSSD) and Communists (KSČM) - mostly oppose the idea.
A negative attitude toward the plan is more common and more extreme among the supporters of the latter two parties.
Seven out of ten want the issue to be resolved in a referendum.
