FEATURES, FUNCTIONS AND SPECIFICATIONS:
The SP 400 is a low-noise and large-signal-proof mast preamplifier for the 4 m amateur band. It has a coax relay for transmit / receive switching. When using a sequence control, the maximum transmission power is 750 W PEP and 400 W CW / FM / WSJT. This amplifier can be powered remotely via the coaxial cable through its output with supply voltage. Alternatively, local power supply can be provided via the UHF connector with a separate cable. When using the VOX switching, this amplifier must have a permanent power supply during operation. It can be supplied locally or remotely. In VOX mode, the maximum transmission power may not exceed 200 W PEP and 100 W CW / FM / WSJT. The input and output of this amplifier are protected with amplitude limiters to ensure a high level of operational reliability. The input and output circuits of the amplifier have an exact 50 ohm impedance with very low imaginary components. This ensures that the antenna system is loaded with real 50 ohms and that the parameters of the system are not changed. With currently mostly used highly optimized narrowband antennas it is very important that they are terminated with real 50 ohms. Mismatching at the input of the preamplifier used can lead to a change in the parameters of such antennas, which causes loss of gain and changes in the directional characteristic. The SP 400 has a UV-resistant, weatherproof housing and N connector. Hot-dip galvanized clamps and mounting material made of stainless steel are included.
