We renewed our popular AD-14-CQ/A cubical quad antenna and made new AD-14-CQ/B : two element two-band quad for 21 and 28 MHz. The most important thing is that no more tuning is necessary at the installation. At the end of March 99 we plan to develop new three-band (14, 21 and 28 MHz) three-element cubical-quad.
Participation on the exhibition MODERN ELECTRONICS 98 in Ljubljana. We exhibited our new telescopic winch driven mast (as co-operation with the company MASTSYSTEM), which is almost all produced in Slovenia. We exhibited also the original headset used by Ferrari mechanics - of course with our little antennas on it. By the way: in November we've been in Maranello on "working" visit (measurements, modification of headset with antennas in order to improve communication range). All measurements were made on the Fiorano track alongside beautiful noise of testing Ferrari's newest sport car...
Two new antennas: AD-44/BW (flexible) and AD-44/CW (blade); the wideband antennas cover from 30 to 90 MHz intended for use with portable and manpack radios. The model AD-44 is out of production.
CATALOGUES in PDF format are updated (General catalogue and Short Form one too). Due to the size of the General catalogue (over 3 Mb) partial catalogues of the antennas are added (separately for HF; VHF 30-90 MHz; VHF 145-175, UHF 400-1000 and for the 88 - 3000 MHz).
NEW ANTENNA: AD-36/2-10 is "corner reflector" antenna covering from 145 to 175 MHz.
NEW ANTENNA : AD-29/07-5 is heavy duty base station antenna for 0.7 m band and with 5 dBd of gain. The version from 410 to 430 MHz is now used by Slovenian national mobile telephony operator MOBITEL for NMT base stations to increase coverage.
Starting with production of the antennas for Ferrari Formula 1 racing team.
Participation on the exhibition MODERN ELECTRONICS 97 in Ljubljana. Among the other news a prototype of the new telescopic winch driven mast (co-operation with the company MASTSYSTEM AB Sweden) was demonstrated.
NEW ANTENNA: AD-18/D-110 is result of modification of the antenna AD-18/D. Due to the customer's requirements the frequency range is extended up to 108 MHz for covering also standard FM radio band.
NEW ANTENNA: AD-40/07-3 is three-element YAGI antenna covering frequency range from 390 to 475 MHz. A special version of this antenna is named AD-40/NMT-3 and is intended mainly for use with stationary NMT mobile phones (frequency range from 410 to 430 MHz)
NEW ANTENNA: ADS-21/4-W is new wideband mobile antenna covering complete 4 m band from 68 to 88 MHz (SVR<2,5, height 100 cm). The antenna could be used with fixed support ADN-21/UHF or magnet mount ADM-21/UHF. The antenna was developed according to special requirements from German customer.
NEW ANTENNAS : AD-34/2G4 and AD-40/2G4-16 are antennas intended for use in wireless LAN (Local Area Network). The first type is dipole antenna with omnidirectional radiation pattern and the other one is directional (16-elements YAGI antennas enclosed in radome).
