Splitters, Taps, and Combiners

Many customers might require fine-tuning and customizing a system by controlling how much power is sent to each antenna or the amplifier. This allows for users with demanding needs to find the correct balance needed as well as allowing for multiple antennas, protection from poor weather situations and lowering the signal output.  For home installations where RG6 cables are utilized, 75 Ohm options may be available.

Splitters allow for a user to set up multiple inside antennas. This does this by splitting the signal uniformly. There are splitters available to allow for two inside antennas, three inside antennas and four inside antennas. A two-way splitter has a -3dB loss, a three-way splitter has a -4.8dB loss and a four-way splitter has a -6dB loss.  This means if a -70dB signal is fed into a two-way splitter, each of the two outputs will receive a roughly -73dB signal (keep in mind, -73 is lower than -70). Similarly a -70dB signal fed into a three-way splitter will have each of the three outputs receiving a -74.8dB signal and if it is fed into a four-way splitter, each of the four outputs will receive a -76dB signal.

Taps allow for a user to set up two inside antennas while providing a stronger cellular signal to one inside antenna than the other. This is mostly for a set up which has one inside antenna close to the amplifier with the other being far away (requiring a long cable). Due to the loss of the signal from the longer cable, sending a stronger signal through the cable would be the smartest way to go. There are two types of taps available, a 6dB tap and a 10dB tap. A 6dB tap would send a loss of -6dB to one end and a loss of -1.5dB to the other while a 10dB tap would send a loss of -10dB to one end and -0.5dB to the other. For example, feeding a signal of -70dB to a 6dB tap would send a signal of -76dB to one end and -71.5dB to the other while feeding a signal of -70dB to a 10dB tap would send a signal of -80dB to one end and -70.5dB to the other.

A combiner diplexer is designed to combine two outside antennas with one amplifier or two amplifiers with one inside antenna. For areas of incredibly poor cellular signal, two Yagi antennas pointed at different cellular towers can provide for a much stronger signal. This solution can also allow for a cellular signal boosting set up for different types of cellular networks (ie. combining a standard dual-band system or 4G LTE system with an iDEN system or AWS system). This item has N-Female connectors and each port has a loss of 0.5dB.
