Procom has added two new downtilt antennas to its portfolio of antenna products along with a new Tetra base station antenna. It has also launched a new series of high-perfromance 100W diplexers covering the VHF, TETRA and UHF frequency bands.
The company said that the new base antennas are designed by experience engineers with a focus on the professional user. The antennas are of sturdy construction and the use of high-quality materials in construction along with an extensive QA-system ensures the high quality of both electrical specifications as well as mechanical parameters.
They are designed to reduce wind load and reduce space load on tower/antenna sites to give optimum function for many years even under extreme climatic conditions. The antennas are:
• CXL 70-5C/T-7 is a UHF 7dBi (4.8dBd) gain vertically polarized omnidirectional base station antenna with a 7 degree electrical downtilt.
• CXL 70-5C/T-12 is a UHF 7dBi (4.8dBd) gain vertically polarized omnidirectional base station antenna with a 12 degree electrical downtilt.
• CXL TETRA-5SL/ is a UHF 7.5dBi (5.4dBd) gain vertically polarized omnidirectional base station antenna.
Specifications include wind loads up to 160 km/h, temperature ranges from -35°C to +70°C, and Nfemale connectors as standard.
Downtilt antennas allow users greater flexibility in tilting the antenna beam and manipulating the radiation pattern. As a result they allow the operator to minimize interference and to obtain the best quality of service for sites.
Michael Hudson, for Procom UK Systems commented: ‘With these new antennas we are bringing into the market start-of-the-art products with high-performance, reliability which can offer flexible solutions to customers.’
The new series of PRO-DIPX diplexers are designed using the Chebyshev characteristic, which ensures low insertion loss typically 0.6dB and high isolation of 40dB – covering 0-960MHz with SMA, TNC or BNC connectors.
Diplexers are passive devices that multiplex two ports into a single common port. They prevent intermodulation and keep reflected VSWR to a minimum for each of the input transmitters. A typical example would be the simultaneous operation of two different band radio transceivers on a common antenna.
