An electrically insulating gap subassembly for inclusion in a pipe string (30) comprising a pair of tubular members (90, 98) having an electrically insulating isolation subassembly (94) threadably disposed therebetween is disclosed. The electrically insulating isolation subassembly (94) has an anodized aluminum surface that provides electrical isolation to interrupt electrical contact between the two tubular members (90, 98) such that electromagnetic waves (46, 54) carrying information may be generated thereacross.
