WARNING: The transistors in the RF finals are expressly not covered by the manufacturers warranty. We do not accept 'change of mind', 'upgrade', 'not quite what I wanted' or 'swap' returns so be careful this is the model you want before purchasing.
Please Read Before Using:
- Do not use outside of the specified frequency ranges as damage may occur.
- Care needs to be taken that the antenna you are connecting to is in good condition and the VSWR is less than 1.5:1 on the frequency you are transmitting on.
- For higher power amplifiers (100+ watts) we recommend a single band antenna tuned to the frequency you are transmitting on.
- Never use an amplifier to attempt to compensate for a poorly tuned, high SWR antenna, for poor quality coaxial cable or connectors.
- We strongly recommend not using a power amplifiers with an indoor or loft antenna.
- Check the transmit power immunity of your vehicle if vehicle mounting as this may damage the electronics and/or disable your vehicle or functions of your vehicle.
- Be certain that the supply current from your power supply is ample for the peak current draw of the amplifier otherwise damage to the amplifier may occur.
- Be very careful when operating at high power and keep well clear of the transmitting antenna.
- Always check your antenna and feedline performance with an SWR meter on low power before increasing power to maximum.
- Do not overdrive the RF input of the amplifier.
- Do not operate the amplifier without a 50 ohm antenna or overrated dummy load connected to the antenna output.
- Do not operate your amplifier in hazardous environments - ie service stations, mines, etc
- Regularly or continuously test your antenna and feed line SWR for unexpected performance issues.
- Disconnect the antenna if lightning or storm activity is occurring nearby.
- Do not touch the antenna or exposed antenna connections when transmitting.
- Stop transmitting immediately if a fault appears.
