Custom Designed Systems
RF240 coaxial cable is supplied as standard with all kits.
RF240 is a low-loss, low-noise equivalent to Times Microwave’s LMR240.
Kits come with a choice of pre-cut and terminated cables at 10m, 20m and 30m lengths.
If a longer cable is required we can:
- Upgrade to a cable that inserts less loss through attenuation, such as RF400
- Insert a GPS amplifier in the cable run
…..or both of the above
Example of a custom-designed system
- The antenna feeder cable is quite long so an amplifier boosts the signal by 16dB.
- The splitter distributes the incoming signal to up to five repeater units.
- DC power from one of the repeater units is passed through the coaxial cables to provide power to the amplifier and the antenna.
Components of a custom-designed system GPS repeater system
GPS amplifier
Allows for longer cable runs between the outdoor GPS antenna and the indoor repeater unit(s).
Signal gain is +16dB across the GNSS band of 1200 to 1700 MHz; supporting GPS L1 and L2, GLONASS and Galileo simultaneously.
A built-in filter removes unwanted signals that may have entered the cable.
The amplifier requires a 5V DC power supply which is fed through the coaxial cable from the attached repeater unit(s).
The DC voltage is also passed through to the outdoor GPS receiving antenna.
GPS splitter 1:2
Connects the the signal from one external antenna to up to two repeater units.
Supports GPS L1 & L2, GLONASS, Galileo.
It is sometimes necessary to use a separate amplifier in conjunction with the splitter to ensure adequate signal strength to all the repeaters – if in doubt call or email FalTech for technical advice.
If the signal is to be transmitted to just one repeater (for example if a second device is to be installed later) the unused port should be fitted with a 50 ohm terminator.
GPS splitter 1:5
Distributes the incoming signal from one external antenna to up to five GPS repeater/receiver units.
Supports GPS L1 & L2, GLONASS, Galileo.
- Sometimes necessary to use a separate amplifier with the splitter to overcome signal losses through attenuation.
- Upgrading to a lower-loss cable may also be enough – if in doubt call or email FalTech for technical advice.
- Spare/unused ports should be fitted with a 50 ohm terminator.
- One port passes DC voltage from repeater to GPS antenna, to provide power for LNA (-4dB signal loss).
- The other four ports are DC-blocked (-12dB signal loss).
Combined amplifier/splitter 1:3
This versatile unit is a combined GPS amplifier/splitter.
It has a built-in 16dB line amplifier with a splitter that passes signal to up to three separate GPS repeater/receiver units.
Three configuration options:
- Inline amplifier with 16dB gain
- GPS splitter unit (1:3)
- Combined line amplifier with splitter 1:3
