Shortwave tuned amplifier designed for receive-side signal enhancement.\u003cbr\u003e2. Adjustable narrowband tuning range from 3MHz to 30MHz with approximately 1MHz bandwidth.\u003cbr\u003e3. Incoming signals from the ANT port are filtered by the built-in tunable bandpass filter and then amplified by a low-noise amplifier before output to the RX\/TX port.\u003cbr\u003e4. The tunable filter helps emphasize the selected frequency range while reducing unwanted signals on adjacent frequencies. Gain is adjustable from 0 to 30dB to help match different signal strengths and minimize overload.\u003cbr\u003e5. Built-in bypass function supports direct signal path operation when needed. Maximum rated voltage: AC 440V \/ DC 120V. Maximum rated current: 8A . Please operate within the specified limits.\u003cbr\u003e6. Rear panel connectors are BNC female. Connect the ANT port to the antenna and the RX\/TX port to the radio, receiver, or other compatible equipment.\u003cbr\u003e7. For safe operation, switch the amplifier off or use the external control connection before changing system routing.\u003cbr\u003e8. The control interface is a 3.5mm mono audio female connector.\u003cbr\u003e9. Requires a 12V or 13.8V regulated DC power supply. Power connector size: 5.5 ĄÁ 2.1mm, center positive. Please confirm correct voltage and polarity before use.\u003cbr\u003e10. Press the black button on the right side of the front panel to power on. The green indicator light will illuminate. The red indicator light will be active during bypass\/control operation.\u003cbr\u003e11. TUNE knob adjusts the filter center frequency from 3MHz to 30MHz.\u003cbr\u003e12. FINE TUNE allows precise adjustment at the selected frequency.\u003cbr\u003e13. GAIN controls amplification level.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePackage Included:\u003c\/strong\u003e\u003cbr\u003e1 x Shortwave Tuned Amplifier","brand":"bruceshark","offers":[{"title":"Default","offer_id":54214654001516,"sku":"E002-D104","price":177.09,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0332\/4772\/3658\/files\/1213555268420370432.jpg?v=1787023464","url":"https:\/\/bruceshark.com\/en-nz\/products\/shortwave-tuned-amplifier-3-30mhz-frequency-coverage-adjustable-gain-0-30db","provider":"Bruceshark","version":"1.0","type":"link"}
