    New Trucker Antenna: Sirio Performer 5000 3/8 10m & CB Mobile Trucker Antenna




    Special Design for Truckers, Coming soon!

    The new SERIES 5000 has been designed as a new series of vehicular antennas for 27 MHz or 10m HAM band to assure very good performances and high power handling. Thanks to its coil made of big section copper wire, TURBO 5000 and PERFORMER 5000 can bear very high powers up to 1500 Watts countinuous or 5000 Watts short time. It's very important to make use of the correct cable, in particular, we recommend to use a teflon RG303 for power more than 600 Watts to guarantee your tranceiver's life. The whip is made of 17/7 PH stainless steel and all the metallic parts are of chromed brass to get the best robustness. The Non-PL model are standardly supplied with 4m cable RG58 C/U for hole installation but they can be also fitted on magnet mount or brackets supplied with UHF connector.

  • New RM Italy LA 250 Series VHF 2 meter Linear Amplifier Just passed FCC Lab Test


    The New RM Italy LA 250 VHF 2 meter Amplifier just passed the FCC lab test, It will come to the US Market soon


    The LA-250 is a 200W 140-150MHz amplifier, at 1 to 20W input (13.6V 30A). It uses 4 Mitsubishi RD70 Mosfets mounted on a copper heat spreader (200x60x3mm).





    It is available in two versions one with and one without top mounted fans. There is an external PTT input but it can be used also without due to the built-in HF-VOX. The front panel features an LCD display which shows input power, output power, heat sink temp and output VSWR. There is the ability to change the intensity of the backlight.
    The CPU keeps an eye on input power, temperature and VSWR and will if necessary disable the amplifier from transmitting if there is fault. Any errors will also be recorded and will be available for later recall for diagnostic purposes by either the manufacturer or his distributors.

    Weight is approximately 4kg. Dimensions are approximately 240x420x70mm for the non fan version and an extra 10mm of height, 80mm, for the fan version.

  • RM Italy HLA 300 Plus Linear Amplifier vs. the New RM Italy HLA 305v Plus Linear Amplifier

    So What's the new RM Italy HLA 305v plus is different from the classic RM Italy HLA 300v plus?





    The classic HLA 300 series amp still a very good amp!

    The new HLA305 is the next generation of the HLA 300 series amplifier. New features include:

    page1image4840 page1image5000
    1. Larger Heat Sink. A new die has been designed that provides increased dissipation by about 25%, which in turn increases the internal PCB size allowing improved layout of some of the critical circuit components. This allows the amplifier to be used at higher duty cycles without the requirement for cooling fans. A version is also available with fans, that are now larger diameter and run much quieter than previous models. This will afford the contest operator a much quieter noise level.

    2. More linear input circuit. This improves the measurement of both frequency and input power.

    3. More powerful processor. Allows improved control of the amplifiers protection circuits and general functionality. In addition we have introduced a new system for digital to analogue conversion that allows measurement of all values at the same instant instead of se-
      quentially, (sample and hold). We have also added measurement of the input current and redesigned the SWR sensor circuit which is now done with a ’Tandem Match’ that results in better linearity and precision.

    4. LCD Display. The introduction of a more powerful processor allows us to use an alphanumeric display which is able to show the status of the amplifier and some of the operating parameters.

    5. Improved Filtering. The six Low Pass Filters have been completely redesigned and are now 5 pole Cauer designs. This has significantly improved the attenuation of the harmonic output. We also now use larger (AMIDON) cores that avoids core saturation and with the use of high quality Siler Mica capacitors that are better able to cope with excessive voltage in the case of a poor load.

    6. Redesigned RF stage. With respect to the old HLA300 we now use an adaption of a classic Motorola design which although more complex improves linearity with respect to frequency and reduces signal distortion. The collector supply is now provided via the feedback transformer so the DC supply is no longer passing through the output matching transformer which greatly reduces the possibility of core saturation.

    7. Bias Circuit. This has been completely redesigned and is now stabilised in both voltage and temperature to keep the bias supply constant with changing supply loads and transistor temperature.

    8. Faster RX/TX Switching. RX/TX switching time has been greatly reduced, (After band detection has been completed). 

    RM Italy HLA 305 V Plus Professional Linear Amplifier With Fans passed the FCC Lab Test




    The New RM Italy HLA 305v HF Wide band Amplifier just passed the FCC lab test, 11 meter blocked, It will come to the US Market fall 2014!


    The new RM Italy HLA 305 V (with ventilator) is a Wideband compact Amplifier for the HF band covering from 1.8 to 30 MHz.
    The HLA-350 operates from 1.8 - 30 MHz and its output power is 250W, with an input power of 1-10 Watt. There are 6 filters built-in to suppress harmonics, which are switched automatically but can also be switched manually for special operating conditions.
    At the front panel there is a switchable input attenuator as well as a LC-display which can show input power, output power, heat sink temperature or output SWR. The intensity of the background light is adjustable. The CPU monitors input power, temperature and VSWR. Any error status are saved so that the manufacturer or authorised reseller can read them out for diagnose purposes. The PA has a PTT input (use for SSB recommended), but also a built-in HF-VOX.
    For optimal heat distribution the PA transistors are mounted on a large copper heat spreader (200x60x3mm). The HLA-350 has an oversized heatsink and therefore remains cool during operation.
    For operation the PA requires 13.5V at max. 34A, dimensions are about 240x420x70mm and weight 4,3 Kg.
    The model HLA-350V comes with 2 additional temperature-controlled fans and thus has a total height of 80mm instead of 70mm. The DC cable is removable.
