Wilson 951150 RG11 F-Male Cable is a 75ohm 50ft black cable featuring two F-male connectors (regular household TV video cable) on both ends. This ultra low-loss coax cable features almost the same loss as an LMR400 cable, and 2/3rds the loss of the RG6 cable. This is a high performance commercial grade cable. Used for connections between the amplifier to both inside and outside antennas, taps, splitters or lightning surge protector.
