Egyptian President Anwar Sadat came away from his first meeting with Secretary of State Alexander M. Haig Jr. satisfied and delighted that the Reagan administration has dropped Israeli-sponsored proposals politically unacceptable to Egypt, high Egyptian sources said today.

Although key issues remain unresolved, the sources made clear their relief that Haig appeared to understand Egypt's earlier concern that the administration seemed to be influenced by Israeli thinking on regional issues such as downgrading the Palestinian problem in favor of an anti-Soviet crusade as well as bilateral U.S. Egyptian matters.

The sources close to Sadat were pleased that the United States no longer was toying with apparent Israeli-sponsored ideas about a multinational peacekeeping force in the Sinai Peninsula.

Similarly, the United States had avoided trying to persuade Egypt to accept trying to persuade Egypt to accept written assurances about the Red Sea air and naval installation at Ras Banas, Egypt, for which Congress has been asked to appropriate $106 million.

"The Americans know we cannot give them a base or a base disquished as facilities," the sources said in nothing both sides had agreed only to remain "in touch" on this issue.

The sources were pleased that Haig had failed to raise the possible use by U.S. forces of two Israeli-built air bases in the portion of the Sinai Peninsula still held by Israel. The territory is the third and final portion of Egyptian territory seized in the 1967 war that Israel still controls. It is scheduled to be evacuated by April 1982.

Israel reportedly suggested to the Reagan administration that U.S. use of Eitam in the north and Etzion in the south would reassure Israeli public opinion about security in the demilitarized border zone to be patrolled by a multinational force.

The sources also stressed that Egypt remained opposed to the Israeli-backed inclusion of 1,000 U.S. troops in that force on grounds their presence would justify charges of superpower interference in Egypt both in egyptian and regional public opinion.

The United States and Egypt decided yesterday to defer any conclusion on that although the sources stressed they still felt any U.S. role should be limited to logistics.

Similarly, the sources were pleased by Haig's rejection of other Israeli-supported efforts to use an American presence in the Sinai detachment as a "spearhead" for a "disguised" equivalent of the controversial Rapid Deployment Force to protect Persian Gulf oil.

Also laid to rest were earlier suggestions the United States was seeking to use Sharm el-Sheik, near the southern tip of the Sinai Peninsula, as a base for the Rapid Deployment Force.

The sources noted that the Egyptian-Israeli peace treaty expressly forbade use of Sharm el-Sheik for anything but civilian purposes.

The treaty also stipulated, the sources noted, that the multinational force must be stationed at Rafeh near the Mediterranean and Sharm el-Sheik. fSadat opposes U.S. use of Et-zion and Eitam, it was noted.

Lest the composition of the multinational force become an issue in Israel's election campaign, the sources said, efforts would be pushed ahead rapidly to evaluate the seemingly slight chance of U.N. Security Council sponsorship for the peace-keeping operation in the Sinai. A Soviet veto is expected.

No conclusion was reached about eventual U.S. participation in such a force and the sources said, "We will cross that bridge when we come to it." But they appeared cautiously optimistic about chances of recruiting potential nations to designate troops for the multinational force.

The source said Egypt had signaled its concern publicly and through diplomatic channels about various reports from Washington about Middle East Policy.

The Reagan administration had dissipated many of these worries before Haig arrived here Saturday on the first stop of his familiarization trip to the Middle East, the sources said in nothing their satisfaction with their first contact with the new secretary of state.
