สำคัญ:
– Ensure proper shielding between the final stage and audio stage with exciter. Install a good ตัวเก็บประจุแบบป้อนผ่าน on the +48V supply wiring to prevent RF interference.
– Excessive drive levels can damage the amplifier. Ensure your equipment includes appropriate protection circuits.
– Amplifier efficiency is dependent on supply voltage. For maximum efficiency, adjust the supply according to the desired output power, typically at 1-3 dB gain compression.
– RF pallets are sensitive. If you lack sufficient experience, consider a fully finished product. Misuse can lead to damage, and no warranty is provided. Every pallet is tested and fully operational upon dispatch.
– Ensure proper airflow across the pallet to prevent overheating. Pre-order now to secure yours!
– You can find special adjustable 50-65V power supply for this amplifier ที่นี่! Use a good strong fan!
Manuals and drivers for most products are available under the Additional Information tab above, just under the prices. Some old manuals are ที่นี่.

Warnings and Notes:
– Do not exceed maximum supply voltage for your pallet to avoid damage.
- ใช้ สายโคแอกเชียล PTFE for RF input (RG178) and output (RG178 or RG142). Keep leads very short. This หน้าแปลนตัวเมีย N สำหรับ RG142 หรือ .141 กึ่งแข็ง – ติดตั้งง่าย สมบูรณ์แบบ!
– A heatsink is essential. Ensure proper airflow across the pallet to prevent overheating.
อุปกรณ์เสริมที่แนะนำ:
เราแนะนำ antenna analyzer for checking SWR of the antennas. Grounding kits for lightning protection can be purchased ที่นี่. They should be installed at the antenna (if needed, most dipoles are grounded anyway), at the tower base and at the point of entrance into transmitter building. Also use เทปปิดผนึกตัวเอง which turns into rubber and protects moisture from entering your antenna system. You might also need Antenna tower to place the antennas. สายโคแอกเชียลและขั้วต่อ are available as well.
