Safety and performance
High performance proFIL™ technology enables modern communications without compromising safety and performance. Its low loss and high isolation output ports improve the overall performance of the communication system in comparison to the traditional one antenna – one radio approach.
The proFIL™ family of products consists of antenna combiners, which are designed to reduce the total number of antennas on the topside of the vessel. Thus the immediate effect is reduced interference. Their high performance filtering removes other spurious signals form nearby radios and high isolation technology increases the virtual distance of connected radios.
Design your own vessel to be intermodulation interference free or ask us to do it for You!
The best protection and immunity against interference is reached together with the proISO™ technology.
Power Line Noise Filters
proFIL™ series Power Line Noise filters is designed to reduce noise and interference from the switched mode power supplies. They attenuate effectively low frequency switching frequencies and higher harmonic frequencies caused by unintentional interaction with high power RF-transmissions.
Impedance Matching Filters
proFIL™ series of Professional Impedance Matching filters are designed to maximize the performance of receiver while minimizing the conductive noise through cables by taking advantage of inbuilt proISO™ technology.
Coaxial Cable Interference Filters
proFIL™ series Coaxial Cable Interference Filters are designed to minimize interference that is travelling backwards in coaxial cables due to antenna circuit mismatch, reflections around antenna and cable faults.
Promarine filters offer a simple, yet effective solution by allowing different receivers to utilize common antenna, so that thicket of antennas on ship's topside can be thinned out and interference significantly reduced.
The use of proFIL™ family of antenna combiners makes the design of communication system trouble free and easy. It helps in reducing the interference between communication system. Being a completely passive technology, it is maintenance free and reliable and it does not cause further interference.
Tactical Communication Products
Promarine’s tactical communication products are specially designed for fast and small patrol vessels. They allow the installation of multiple radios without increasing the amount of antenna and thus risking vessel’s mission capabilities.
proFIL signal and power filter products
proFIL 0100 Power Line filter is both common mode and differential mode noise filter with safety ground connection. It is very effective against conductive interference starting from <1MHz up to 300MHz.
proFIL 1010 series Coaxial Cable Interference Filters are designed to minimize interference that is travelling backwards in coaxial cables due to antenna circuit mismatch, reflections around antenna and cable faults.
proFIL Splitter products
proFIL 1320 an active Navtex antenna (0.1MHz-30MHz) power feeder. It is intended to be used when MF/HF DSC receiver or Navtex receiver is connected to an active receive antenna and receiver itself cannot source power to antenna.
proFIL 1321 splits existing MF/HF radio’s separate DSC receiving antenna (typically long wire whip) with Navtex or WeatherFax receiver. It can be used to split any 0.1-100MHz antenna with two receivers.
proFIL 1322 splits an active Navtex antenna (0.1MHz-30MHz) with Navtex and WeatherFax receivers or MF/HF DSC receivers. It can be used to split any active Navtex antenna that tolerates +10VDC voltage from the receiver.
proFIL 1323 proFIL 1323 splits existing FM receiver’s antenna (like FAME1) with Navtex or WeatherFax receiver and adds amplifier for Navtex frequencies. It can be used to split any FM/VHF range antenna that has satisfactory response to lower (0.1-30MHz) frequencies.
proFIL Combiner products
proFIL 4120 is designed to be used with tactical wideband antennas ranging from 30MHz up to 512MHz. Its low loss design enables the use of high power transmitters simultaneously. proFIL 4120 operates in ranges 30 – 80 MHZ / 108 – 400 MHz.
proFIL 4201 combines transmitting AIS (class B and class A) with receiving VHF DSC antenna. It is especially useful in situations where there is an existing class A VHF DSC receiver in dedicated antenna and AIS transponder is to be installed.
proFIL 4211 is designed to be used with tactical wideband antennas ranging from 30MHz up to 512MHz. Its low loss design enables the use of high power transmitters simultaneously. proFIL 4211 operates in ranges 80 – 170 MHz / 225 – 400 MHz.
proFIL 4401 is a state of the art antenna combiner that reduces the total antenna count by 4:1 ratio. It combines broadcasting FM receiver, marine VHF, governmental TETRA and 450MHz UHF data communications bands.
Compact and high performance antenna combiner up to 6GHz WiFi frequency. It is ideally used with proTAC 5311 4G LTE antenna to split it with LTE modem and WiFi router. proFIL 5220 covers communication bands from 80MHz up to 6GHz.
Compact and high performance antenna combiner from 300 MHz up to 6GHz WiFi frequency. It is ideally used with proTAC 5315 Wideband LTE antenna to split it with 380 MHz Tetra or 450MHz LTE modem and 4G LTE Modem
