LF Engineering SPL-2/75 AM-BC User manual

Model SPL-2/75 AM-BC
Two-Way Splitter/Combiner
The SPL-2/75 AM-BC Two-Way Splitter/Combiner provides an
impedance matched 75 ohm coaxial connection for two receivers
when feeding signal from a single source. Typically used for distrib-
uted cabling systems requiring impedance matched taps for multiple
receivers, or when combining two antennas for diversity reception.
The splitter consists of a low loss toroid matching network designed to
maintain a low impedance signal split with high isolation between ports.
Proper impedance matching is necessary for optimum performance
especially when running feeder cable over long distances within a
building.

In splitter configuration, two receivers may be fed from one
antenna. Shown below are four antenna configurations typically
used with the SPL-2/75. Use coaxial extensions in lengths up to 100
feet using 75 ohm 1/4 inch coaxial cable.
The cumulative system loss is the total loss (in dB) of all feeder and
extension cables, and the splitter loss for the SPL-2/75 itself.
In combiner configuration, two different antennas may be used
to feed one broadband receiver. Shown below are two suggested
antenna configurations that may be used with the SPL-2/75.
The cumulative system loss is the total loss (in dB) of all feeder and
extension cables, and the splitter loss for the SPL-2/75 itself.
