Narrative:

Aircraft X was descending to 3;000 about 15miles southwest of ixa airport for the visual approach. Aircraft Y came up on my frequency looking for flight following southbound. I gave him a code; told him to ident; and told him about the inbound traffic landing at ixa. The second I saw aircraft Y's code I transmitted for the citation to stop decent and informed him about the traffic. Then I told aircraft Y about the traffic; which at that time was already past. Not knowing that aircraft X was out of frequency range and could not hear anything I said about the traffic. I never did get contact with aircraft X and he landed without any approach clearance. The only thing would be better radar and radio coverage for that area. I never saw the departing aircraft until he was at 2;800 feet. Aircraft X never heard my traffic calls because he was out of radio coverage.

Title: ZDC ARTCC Controller reported being unable to provide separation to aircraft in conflict and subsequent approach clearance; due to limited radar and radio coverage in the area.

Narrative: Aircraft X was descending to 3;000 about 15miles southwest of IXA airport for the visual approach. Aircraft Y came up on my frequency looking for flight following southbound. I gave him a code; told him to ident; and told him about the inbound traffic landing at IXA. The second I saw Aircraft Y's code I transmitted for the citation to stop decent and informed him about the traffic. Then I told Aircraft Y about the traffic; which at that time was already past. Not knowing that Aircraft X was out of frequency range and could not hear anything I said about the traffic. I never did get contact with Aircraft X and he landed without any approach clearance.
