Overview
The LA-81 is a passive device (no power supply needed) that takes four (4) incoming RF signals and combines them into one (1) outgoing antenna source. The combiner is used in applications where up to four (4) different antenna sources are required and only one (1) antenna output is available or desired.Includes

Requirements
-
LA-390 RG-8 50 Ohm Preassembled Coaxial Cable (Per ft.)
Gives the right amount of cable for your FM/IR predesigned system.
-
LA-112 RG-58 50 Ohm Coaxial Cable (Per ft.)
RG-58 50 Ohm Coaxial Cable is used when more distance is needed for the antennas to have better coverage.
-
LA-391 RG-58 50 Ohm Preassembled Coaxial Cable (Per ft.)
Gives the right amount of cable for your FM/IR predesigned system.
-
LA-113 RG-8 50 Ohm Low-Loss Coaxial Cable (Per ft.)
RG-8 50 Ohm Coaxial Cable is measured and cut per foot. It is best used when more distance is needed for the antennas to have better coverage.
