Proper installation of your Comet SMA-24 antenna is crucial for optimal performance.
3.1 Attaching Eriali
- Identify the antenna connector on your handheld transceiver. The SMA-24 is designed to be compatible with BNC, SMA, and SMA female connector types.
- Carefully align the antenna's connector with the transceiver's antenna port.
- Gently screw the antenna onto the port clockwise until it is finger-tight. Maṣe ṣe apọju, as this can damage both the antenna and the transceiver's connector.
- Ensure the connection is secure but not forced.

Once the antenna is securely attached, your handheld transceiver is ready for operation.
- Aṣayan Igbohunsafẹfẹ: Ensure your transceiver is set to frequencies within the 2-meter (VHF) or 70-centimeter (UHF) bands for optimal performance with this antenna.
- Iṣalaye eriali: For best results, hold your transceiver vertically. While the antenna is flexible, maintaining a generally upright position helps maximize signal propagation.
- Awọn Okunfa Ayika: Performance can be affected by obstructions such as buildings, terrain, and dense foliage. Try to operate in open areas when possible.
5. Itọju
To ensure the longevity and continued performance of your Comet SMA-24 antenna, follow these maintenance guidelines:
- Ninu: Wipe the antenna with a soft, damp aṣọ láti mú ìdọ̀tí àti eruku kúrò. Yẹra fún lílo àwọn kẹ́míkà líle tàbí àwọn ohun ìfọmọ́ tí ó ń pa ara.
- Mimu: While the antenna is designed with flexible material, it is important to handle it with care. Avoid excessive bending, twisting, or sharp impacts, especially near the base connector. Repeated or forceful bending can compromise the internal structure and lead to damage.
- Ibi ipamọ: When not in use, store the antenna in a clean, dry place, away from extreme temperatures and direct sunlight.
