SSB Electronic LNA-30 Broadband 5 kHz – 30 MHz Low Noise Mast-Mount Preamplifiers

SSB Electronic LNA-30 Broadband 5 kHz – 30 MHz Low Noise Mast-Mount Preamplifiers cover the VLF, LF, and MF range, including the 2200 through 10 meter Amateur bands. Only for receiving applications, the LNA-30 is used to transform a simple wire or small whip antenna into a powerful broadband receiving antenna. This allows, for example, an SDR receiver to be operated in an unfavorable location with limited space and still deliver very good results. A skimmer or

The LNA-30 amplifies the signals received by about 20 dB. The operating power can be varied for effect from 12 and 24V, with higher gain achieved at 24V, but the lowest figure at 12V. A very RF quiet, well filtered linear power supply should be used, not a switching power supply, which connects to this mast-mounted preamplifier via a separate coaxial cable; a UHF female handles the power input. The LNA-30 handles the RF separately with Type-N female connectors for antenna and receiver. When power is removed the preamplifier turns of and no signal from the antenna passes, making this an "always on" broadband preamplifier.

The LNA-30 may be mounted on masts up to 2.25 in. (58mm), is weatherproof, and should be placed outside, close to the receive antenna. This preamplifier cannot pass RF power and is not suitable for transmitting operations.
