ΣΠΟΥΔΑΙΟΣ:
– Ensure proper shielding between the final stage and audio stage with exciter. Install a good πυκνωτής τροφοδοσίας 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 εδώ! Use a good strong fan!

Warnings and Notes:
– Do not exceed maximum supply voltage for your pallet to avoid damage.
- Χρήση Ομοαξονικό καλώδιο PTFE for RF input (RG178) and output (RG178 or RG142). Keep leads very short. This N θηλυκή φλάντζα για RG142 ή 0,141 ημιάκαμπτη – εύκολη εγκατάσταση είναι τέλειο!
– A heatsink is essential. Ensure proper airflow across the pallet to prevent overheating.
Προτεινόμενα αξεσουάρ:
Συνιστούμε αναλυτής κεραιών for checking SWR of the antennas. Grounding kits for lightning protection can be purchased εδώ. 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 αυτοσφραγιζόμενη ταινία which turns into rubber and protects moisture from entering your antenna system. You might also need Antenna tower to place the antennas. Ομοαξονικό καλώδιο και σύνδεσμοι are available as well.
