Technical description MHP-200

The mast preamplifier MHP-200 is based on the LNA-200 with additional transmit/receive switching. The switch-over provides a decoupling of approx. 60 dB, the input is additionally protected with limiters. The gain is typ. 24 dB, the maximum permissible transmit power is 1500 W, the noise figure is 0.3 dB. The mast VV is intended for installation close to the antenna, the housing is weatherproof and UV-resistant. The remote power supply (12VDC, approx. 460 mA) is provided via the coaxial cable. A sequencer is urgently recommended for operation.

Application description MHP-200

The MHP-200 is a mast preamplifier for the highest demands. The high amplification is suitable for use with "weak signal" modes such as Tropo-DX or EME. The maximum permissible transmit power of 1500 W makes this preamplifier very suitable for contest or EME operation. For operation, the MHP-200 must be supplied with 12V phantom power via the coaxial cable; the use of an appropriate sequencer is recommended. The transmit/receive switch must not be switched under load.
