2. Drošības informācija
Lai novērstu traumas vai aprīkojuma bojājumus, vienmēr ievērojiet šādus drošības pasākumus:
- Barošanas avots: Ensure the antenna is connected to a stable DC12V power source. Incorrect voltage can damage the antenna's internal motor.
- Montāža: Securely mount the antenna to your vehicle. Loose mounting can cause the antenna to detach during motion, leading to accidents or damage.
- Klīrenss: Be aware of the antenna's length (1.85m) when driving, especially near low overhead structures, bridges, or power lines.
- Laika apstākļi: Avoid operating the antenna during severe weather conditions, such as thunderstorms, to prevent lightning strikes.
- RF ekspozīcija: Maintain a safe distance from the antenna during transmission to minimize exposure to radio frequency (RF) energy.

4. Iestatīšana un instalēšana
Follow these steps to properly install your Diamond SD330 antenna:
4.1. Mehāniskā uzstādīšana
- Choose a suitable mounting location on your vehicle, ensuring it is sturdy enough to support the antenna's weight and length. A heavy-duty antenna mount is recommended.
- Securely attach the antenna base to the chosen mount. Ensure a good electrical ground connection to the vehicle chassis for optimal performance.
- Connect your coaxial cable (not included) from your transceiver to the antenna's MP connector.
4.2 Elektriskais savienojums
- Locate the control unit and the power supply cable.
- Connect the control unit to the antenna's control port.
- Insert the cigar plug of the power supply cable into your vehicle's 12V accessory socket. The antenna requires an external DC12V power supply and consumes approximately 100mA.
This image illustrates the components for powering and controlling the Diamond SD330 antenna, including the power supply cable, the control switch (UP/DOWN), and the cigar plug for vehicle power connection.
5. Darbība
The Diamond SD330 antenna features an automatic tuning mechanism to adjust its length for optimal performance across different HF bands.
5.1 Frekvences regulēšana
- Turn on your transceiver and select the desired operating frequency within the 3.5MHz to 30MHz range.
- Use the UP and DOWN buttons on the control unit to adjust the antenna's length. Pressing UP extends the antenna, and pressing DOWN retracts it.
- Observe the SWR (Standing Wave Ratio) meter on your transceiver or an external SWR meter. Adjust the antenna length until the SWR is below 2.0.
- The approximate tuning time is 50 seconds for the full 3.5/30MHz range and 20 seconds for the 7/30MHz range.
This image displays the Diamond SD330 Mobile HF Antenna, showing its physical length when tuned for 3.5MHz and 28MHz frequencies. The antenna extends for lower frequencies and retracts for higher frequencies.
5.2 SWR Optimization
Achieving a low SWR is crucial for efficient transmission and to prevent damage to your transceiver. Fine-tune the antenna length using small adjustments of the UP/DOWN buttons until the lowest possible SWR is achieved for your chosen frequency.
6. Apkope
Regular maintenance ensures the longevity and performance of your antenna:
- Tīrīšana: Periodically clean the antenna elements and base with a soft, damp Izvairieties no abrazīviem tīrīšanas līdzekļiem vai šķīdinātājiem.
- Savienojumi: Check all electrical and mechanical connections regularly for tightness and corrosion. Clean and re-tighten as necessary.
- Motor Mechanism: The internal motor mechanism is sealed. Do not attempt to disassemble it. If you suspect a motor issue, contact customer support.
- Vides iedarbība: While designed for outdoor use, prolonged exposure to extreme weather conditions (e.g., heavy snow, ice, salt spray) may accelerate wear. Consider covering the antenna when not in use for extended periods.
7. Traucējummeklēšana
