The Parsec PC4004L50NM is a four-cable LSR400 kit for Parsec 4-in-1 antennas, delivering four 50-foot LTE cables with N-type male connectors on both ends. It exists for the hardest cabling scenario in cellular WAN installs: a full 4x4 MIMO antenna mounted 50 feet from its router. LSR400 is the grade that makes the distance workable. Its 400-size construction — larger center conductor, heavier shielding — attenuates far less per foot than the LSR240 and LSR200 cables used in Parsec's shorter kits. Across 50 feet, that difference is often what separates a healthy link budget from a marginal one, particularly on the higher cellular bands where coax loss climbs. All four cables arrive matched in grade and length. For 4x4 MIMO and carrier aggregation, branch balance is not cosmetic: mismatched runs skew received signal levels between antenna elements and quietly cost throughput. A matched factory kit removes that variable, and factory-terminated N-type connectors remove crimp quality as a failure mode at the same time. N-male terminations mate with the N-female ports on large outdoor antennas, lightning arrestors, and bulkhead fittings; adapters or pigtails handle the final transition where equipment uses SMA. The kit ships OEM-boxed under one part number with a listed shipping weight of 12.5 lb — a full spool-weight of serious cable that turns a difficult 50-foot, four-feed install into a documented, repeatable package.
