Bigger update of our web pages with many new and renewed products.

October this year will pass 3 years since our relocation to new premises. This move enhanced our production capabilities, improved our stock organization and last but not least improves our test and development capabilities.

 

Aside of a new, fully automated open area test site on the roof for the gain and radiation patterns measurements we have invested over € 300,000 this year in additional test and development equipment. Thus, we enrich the existing measuring equipment with two new network analyzers, new RF power amplifier and new software for analysis and synthesis of antenna matching circuits. In addition, our open area test site was enhanced with special "RF-to-optic" converters that contribute to more accurate measurements of gain and radiation patterns of antennas for portable and handheld radio devices.

 

The result of all these efforts and, of course, efforts of our development team, is visible in many new products as well as improvements to existing ones.

 

VHF 30 - 108 MHz:

 

- Antenna AD-21/6688 is designed to work in the frequency range from 66 to 88 MHz and is composed of the radiator as well as fixed and the magnetic antenna base. The antenna radiator AD-21/6688-N can be used as a standalone antenna for portable radio units, in combination with fixed or magnetic media as a low-profile mobile antenna. This antenna is replacing our old antenna ADS-21/4-W.

 

- Antenna AD-21/3108 is designed same way as the antenna AD-21/6688; the only difference is in the frequency range 30-108 MHz. This antenna is replacing our old antenna ADS-21/4-WB. - Antenna AD-18/CF-388 is so-called "Center-fed" or dipole VHF mobile antenna with similar design as our other VHF/UHF mobile antennas, with the advantage that installation on the metal surface is not needed for normal operation.

 

- Antenna AD-18/CF-3108 has the same shape as the AD-18/CF-388, except it is designed to work on freq. the 30-108 MHz.

 

VHF 108 - 180 MHz:

 

- Antenna AD-21/1318 is intended to work in the frequency range from 130 to 180 MHz and is composed of the radiator as well as fixed and the magnetic antenna base. The antenna radiator AD-21/1318-N can be used as a standalone antenna with portable radio units, in combination with fixed or magnet antenna base as a low-profile mobile antenna. This antenna is replacing our old antenna AD-32. Mechanical design of all our AD-21/… low profile antennas is the same.

 

- Antenna AD-18/H-1318 is a robust vehicle antenna designed for the frequency range from 130 to 180 MHz for use on heavier military vehicles.

 

VHF/UHF 20 - 512 MHz:

 

- Antenna AD-65/B-1512 is a flexible antenna for handheld or portable radio units to work in the frequency range 108-512 MHz. The special design of the radiator provides high gain also in the upper half of the frequency range.

 

- Antenna AD-25/CW-2175 is an antenna with a tape radiator for freq. range from 20 to 175 MHz, intended for covering standard military and civilian VHF frequency range.

 

- Antenna AD-17/C-1512-F is a special version of our standard disc-cone antenna AD-17/C- 1512. All disc and radial elements are made of tape radiators, permanently attached on the antenna head. This way we save time-consuming attachment of all 24 elements, and thus the antenna become usable for military tactical/portable field use.

 

UHF 225 - 512 MHz:

 

- Antenna AD-44/E-HS is a short flexible antenna for handheld radio for freq. range 225 - 512 MHz with SMA female connector.

 

- Antenna AD-22/B-F is also a special version of our standard log-periodic antenna AD-22/B for the frequency range 225 - 512 MHz. Similarly to the antenna AD-17/C-1512-F, all dipole elements are made of tape radiators and are permanently attached to the antenna boom which makes antenna deployment in fraction of time. Thus the antenna is especially useful for tactical/portable field use.

 

- New family of yagi antennas AD-40/07-3T, AD-40/07-7T in AD-40/07-9T is intended for use on TETRA frequency range.

 

- a new high RF power log-periodic antenna AD-22/E covering freq. range 700 - 2800 MHz which makes it ideal for EMC and RF jamming.

 

Antenna Masts:

 

- We have added a new family of telescopic masts STV-G heights up to 5 meters, which are specifically designed to be mounted and used on fire brigade trucks, primarily to raise reflectors.

 

- A new family of lightweight man-portable masts family STM was added for use with lighter antennas and other loads for use in the field. Antenna Accessories:

 

- The ATP-1827/01 is a tripod stand for our VHF/UHF antennas to be used on field.

 

- The ATP-1827/02 is a "Ground Plane" kit for our monopole VHF/UHF antennas to be used with our tubular sectionalized masts ST or telescopic winch driven masts STV.

 

- The ATP-1827/03 is an attachment adaptor for attaching our VHF/UHF center-fed antennas on our tubular sectionalized masts ST or telescopic winch driven masts STV.

 

In addition to these new products, we have done a lot of improvements on our other standard antennas. Thus, we revised the structure of our log-periodic antenna AD-22/A and AD-22/B (increase of freq. range up to 512 MHz, an increase of operating RF power to 500 W), innovate and improve the design of antennas AD-25/CW-… and AD-26/CW-… (increasing RF power handling). Also all of our antennas families AD-25/CW-... and ... AD-44/CW- have tape radiators made from bi-directional bendable flexible tapes coated with a plastic sleeve. The development of manufacturing technology as well as the radiator testing according to strict military standards MIL-STD-810F lasted more than 15 months, but the result of all our efforts is the radiator of truly superior quality, accepted by many of the world's leading manufacturers of military radio equipment.
