POMEMBNO:
– Ensure proper shielding between the final stage and audio stage with exciter. Install a good dovodni kondenzator 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 tukaj! 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 tukaj.
If your web browser blocks the download, you may have to allow it manually. You can send us questions tukaj.
Warnings and Notes:
– Do not exceed maximum supply voltage for your pallet to avoid damage.
- Uporaba PTFE koaksialni kabel for RF input (RG178) and output (RG178 or RG142). Keep leads very short. This N ženska prirobnica za RG142 ali .141 poltrda – enostavna namestitev je popoln!
– A heatsink is essential. Ensure proper airflow across the pallet to prevent overheating.
Priporočena dodatna oprema:
Priporočamo antenski analizator for checking SWR of the antennas. Grounding kits for lightning protection can be purchased tukaj. 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 samolepilni trak which turns into rubber and protects moisture from entering your antenna system. You might also need Antenna tower to place the antennas. Koaksialni kabel in priključki are available as well.
