KAT Projects Worldwide
Station - Egypt:
The first Crossed Field Antenna CFA was installed in 1990 at Tanta radio station 90km from Cairo, owned by the Egyptian Radio TV Union ERTU , in daily service broadcasting at 1161 kHz , 60 kW in regular service since 1994 .
Because the CFA the higher gain of CFA than the Lambda/4 mast antenna; ERTU has decided to reduce the transmission power to 30 kW.
Later, in 1998, another higher power CFA , 100 kW at 864 kHz was installed on the same roof of the 1161 kHz CFA .
No coupling or interference was noticed between the two CFA antennas on the same roof of station when they are worked simultaneously, also no rejection circuits were used for the transmitters .
A new medium wave CFA was built in the UK and set-up by Communications Dynamics Limited (CDL) in collaboration with Kabbary Antenna Technology (KAT). The test results were carried out and confirmed independently by ARQIVA Ltd., which was recommended to CDL by OFCOM for the purpose of independent verification to test the CFA.
The excellent results obtained have confirmed that the elevated CFA had a Relative Emission Efficiency and Bandwidth at least equivalent to a full size Lambda/4 Vertical Monopole Antenna.
This test represent a forward step for a worldwide marketing of the CFA.
