Saudi Arabia builds radio and TV network with Jampro

Saudi Arabia’s Ministry of Culture and Information (MOCI) has selected Jampro Antennas of Sacramento, CA to furnish turnkey broadband DVB-T antenna solutions to a twelve-site network as well as supply FM antenna systems and related RF components.

Alex M. Perchevitch, Jampro president, released details of the project at IBC.

MOCI specified Jampro model JUHD UHF broadband antenna systems to accommodate the digital video broadcasting side of the project. Jampro Proline rigid transmission line and associated accessories round out the system.

For FM transmissions, MOCI chose Jampro model JFVD panel antennas in conjunction with Jampro RCCS Starpoint combiners, which are used to combine two or more high-power FM signals. 

Perchevitch said: “MOCI’s prime purchasing considerations were equipment reliability and durability, but they also insisted on the best performance. They learned from our many other customers in the Middle East and North Africa that our products stand the test of time.”

JUHD Broadband UHF Panel Antennas will be delivered DVB-T-ready for UHF bands IV and V and can accommodate wide bandwidth for multiple channel operation. Built of stainless steel and available with fiberglass radomes for panel protection, JUHD antennas are designed to operate in challenging environments such as Saudi Arabia’s hot, dry desert with great temperature extremes. 

The model JFVD verticlally-polarized dipole, flat-panel antennas ordered by MOCI are also ruggedly constructed. Made of hot-dipped galvanized steel, antenna panels can also be shielded by fiberglass radomes. Each panel has dual dipoles that provide high gain and low downward radiation. JFVD’s have excellent bandwidth (88 to 108 MHz) and pattern stability.  JFVD’s also offer MOCI flexibility in adjusting coverage by being able to select a variety of standard and custom directional patterns. Typical single channel VSWR is 1.1:1 or better.

JFVD antennas used in conjunction Starpoint combiners provide an inexpensive method to combine two or more high power signals. RCCS combiners use bandpass filters and various lengths of transmission line configured to make the filters mutually invisible. Jampro bandpass technology offers intermodulation suppression of both the combined frequencies and any other frequencies in the local environment. Passband insertion loss is minimised by the use of aluminum cavities. Temperature stability is maintained through the use of invar tuning rods on copper center conductors.
