4.2 Memasang Antena

The Harvest X-5000 is designed for mast mounting. Select a sturdy mast or pole that can withstand environmental conditions.

1. Attach the provided mounting brackets to the antenna's base section.
2. Position the antenna on the mast at the desired height, ensuring it is vertical and clear of obstructions.
3. Use the U-bolts and clamps to securely fasten the antenna to the mast. Tighten all nuts firmly, but do not overtighten to avoid damaging the antenna or mast.

4.3 Coaxial Cable Connection

The antenna features an N-series female connector.

1. Connect a high-quality 50-ohm coaxial cable with an N-series male connector to the antenna's base.
2. Pastikan sambungannya ketat dan kalis cuaca menggunakan pita pengedap atau sebatian yang sesuai untuk mengelakkan kemasukan lembapan.
3. Route the coaxial cable away from the mast and secure it to prevent strain or damage.

5. Arahan Operasi

Once the antenna is installed and connected, follow these guidelines for operation:

• Sambungan Pemancar: Connect the other end of the coaxial cable to your amateur radio transceiver's antenna port.
• Band Frekuensi: The X-5000 operates on 144MHz, 440MHz, and 1200MHz. Ensure your transceiver is set to the correct frequency band for communication.
• Had Kuasa: Do not exceed the maximum power rating of 100W (total) for this antenna. Exceeding this limit can damage the antenna and your radio equipment.
• Semakan SWR: Before transmitting, always check the Standing Wave Ratio (SWR) using an SWR meter. An SWR reading above 2:1 indicates a potential issue that should be resolved before transmitting to prevent damage to your transceiver.

6. Penyelenggaraan

Regular maintenance helps ensure optimal performance and longevity of your antenna.

• Pemeriksaan Visual: Periodically inspect the antenna for any physical damage, loose connections, or corrosion. Check the mast and mounting hardware for stability.
• Kalis cuaca: Re-check the coaxial cable connection for proper weatherproofing, especially after severe weather. Reapply sealing tape or compound as needed.
• Pembersihan: Gently clean the antenna elements with a soft cloth and mild soap and water if dirt or grime accumulates. Avoid abrasive cleaners.

7. Penyelesaian masalah

If you experience issues with your Harvest X-5000 antenna, consider the following troubleshooting steps:

• SWR Tinggi:
  • Check all coaxial cable connections for tightness and proper seating.
  • Inspect the coaxial cable for kinks, cuts, or damage.
  • Ensure the antenna elements are fully assembled and not damaged.
  • Verify that the antenna is mounted clear of any metallic obstructions that could affect its radiation pattern.
• Penerimaan/Penghantaran yang lemah:
  • Confirm your transceiver is set to the correct frequency and mode.
  • Check the SWR. High SWR can significantly reduce performance.
  • Ensure the antenna is mounted at an adequate height and clear of local interference sources.
  • Test with a known good coaxial cable if possible.
