CXL 70-1/... Unity Gain Marine Antenna (and Base Station UHF Antenna), 450 MHz Band
This antenna is also highly recommended as Base Station UHF Antenna.
This rod-type UHF antenna is developed for use onboard ships as well as on masts and covers the 450 MHz band in two models.
The 1” revolving nut mounting system makes it possible to mount the antenna in the mast, in the auxiliary mast or on the cross-beam. By means of PROCOM’s flange mount type “FLG”, it can easily be mounted even on the rooftop.
This antenna type can be used for a wide variety of purposes. It is very popular and widely used in connection with 70 cm CELLULAR systems – as for instance the Nordic Mobile Telephone system NMT – making it possible to extend the – normally land based – CELLULAR telephone system for maritime mobile service as well.
The antenna is a 1/2λ design and this means that it needs neither loading coils, groundplane, radials nor other auxiliary arrangements.
Bear in mind that the higher the antenna is mounted the better coverage. Avoid mounting the antenna parallel with or in the neighbourhood of other metal parts, such as masts, supporting wires etc. Free mounting and as high as possible is most preferable, otherwise the SWR and the radiation diagram will be influenced.
The antenna is a grounded radiator antenna and therefore it shows a DC-short across the coaxial cable.
A conical glassfiber tube completely encloses the carefully designed radiating element to assure long dependable service in all climates.

CXL 70-1LW/... Unity Gain, Omnidirectional Marine Antenna (and Base Station UHF Antenna), 450 MHz Band
This antenna is also highly recommended as Base Station UHF Antenna.
CXL 70-1LW/… is a 0 dBd, vertically polarised, omnidirectional marine and base station antenna which covers the 450 MHz band in two models.
The carefully designed, broadbanded 1/2λ dipole radiating element is made of brass tube and sealed in a high-quality conical glassfiber tube with low wind-load.
Provided with the sturdy “LW” mast mount – a lightweight, multipurpose, epoxy-coated mounting bracket made of non-corrosive aluminium.
The accompanying U-bolts and fittings are made of stainless steel. To be mounted on vertical or horizontal mast tubes, 16 to 54 mm in outer diameter. The cable can be led either on the outside or along the inside of the mast tube.
Large bandwidth with respect to both SWR and gain. To substantially reduce noise caused by atmospherical discharges, all metal parts in the antenna are DC-grounded. Consequently, the antenna shows a DC-short across the coaxial cable.
The CXL 70-1LW/… is a vibration-proof, lightweight, slim-line, corrosion resistant, modern style marine and base station antenna.

CXL 70-3/... 3 dBd Gain Marine Antenna (and Base Station UHF Antenna), 450 MHz Band
This antenna is also highly recommended as Base Station UHF Antenna.
This colinear UHF antenna with 3 dBd gain is developed for use on board ships as well as on masts, and thanks to the 1” revolving nut mounting system it can be mounted in the mast, in the auxiliary mast as well as on the cross-beam. By means of PROCOM’s flange mount type “FLG”, it can also be mounted on deck or rooftop.
The CXL 70-3/… is in widespread use in connection with 450 MHz CELLULAR systems.
The antenna makes it possible to extend the – normally land based – CELLULAR telephone system service for maritime use as well, and here the 3 dBd gain of the antenna comes to definite advantage.
Bear in mind that the higher the antenna is mounted the better coverage. Avoid mounting the antenna parallel with and in the neighbourhood of other metal parts, such as masts, supporting wires etc. Free mounting and as high as possible is most preferable, otherwise the SWR and the radiation diagram will be influenced.
The antenna needs neither loading coils, ground-plane, radials nor other auxiliary arrangements. The antenna is a grounded radiator antenna and therefore it shows a DC-short across the coaxial cable.

CXL 70-3LW/... Lightweight, Medium Duty, 3 dBd Marine Antenna (and Base Station UHF Antenna), 450 MHz Band
This antenna is also highly recommended as Base Station UHF Antenna.
CXL 70-3LW/… is a 3 dBd, vertically polarised, omnidirectional marine and base station antenna, which covers the UHF band in 4 models with up to 10 MHz overlap.
The antenna meets the demand for a medium duty, cost-effective antenna to be chosen, when the exceptional mechanical capabilities of our extremely rugged heavy-duty model CXL 70-3C/… are not needed.
The carefully designed radiating element is sealed in a high-quality, conical glassfiber tube with low wind-load, which will ensure undisturbed performance by corrosive environments.
Provided with the sturdy “LW” mast mount – a lightweight, multipurpose, epoxy-coated mounting bracket made of non-corrosive aluminium.
The accompanying U-bolts and fittings are made of stainless steel. To be mounted on vertical or horizontal mast tubes, 16 to 54 mm in outer diameter. The cable can be led either on the outside or along the inside of the mast tube.

CXL 70-5C/... Colinear, Heavy-Duty 5 dBd Marine Antenna (and Base Station UHF Antenna), 450 MHz Band
This antenna is also highly recommended as Base Station UHF Antenna.
CXL 70-5C/… is a 5 dBd, vertically polarised, omnidirectional marine and base station antenna, which covers the 380–470 MHz band in 4 models with up to 10 MHz overlap.
The antenna is provided with our heavy-duty type “C” universal fixation bracket made of epoxy-coated, seawater resistant aluminium. The accompanying U-bolts and fittings are made of stainless steel.
CXL 70-5C/… can be mounted on 27 to 65 mm dia. mast tubes, and it is possible to lead the cable either along the inside or on the outside of the mast tube.
The carefully designed radiating element is sealed in a high-quality, conical glassfiber tube with low wind-load, which will ensure undisturbed performance by corrosive environments.
To substantially reduce noise caused by atmospherical discharges, all metal parts in the antenna are DC-grounded. Consequently, the antenna shows a DC-short across the coaxial cable.
