The MVV 1296-VOX mast pre-amp is a low-noise antenna pre-amplifier in a double-shelled housing. The outer housing made of ABS is weatherproof and suited for mast mounting. The inner metal housing ensures a high shielding factor against unwanted irradiation and protects the components of the amplifier against harmful environmental influences effectively.The MVV 1296-VOX has two stages to gain enough amplification for longer feed lines, also. The input stage is equipped with a low-noise microwave GaAs FET, the second stage uses a microwave IC (MMIC). The amplification is continuously adjustable, which helps to adjust to particular cable lengths. A three-circuit stripline filter provides the necessary preselection.The MVV 1296-VOX is equipped with UHF-capable print coaxial relays, which ensure a low-attenuation carriage of the transmission power. Transmit/receive changeover is done via a PTT input or automatically by the integrated HF-VOX. With the protection circuit even in VOX operation a reliable transit/receive changeover up to 180 Watt at SSB mode is guaranteed. The operating voltage is supplied either via a separate two wire line or by remote power via coaxial cable. If the transceiver does not already provide 12V voltage for powering a pre-amp via coaxial cable, then another Bias-T (Order No. 26137.23) for remote power supply is required. Delivery includes mast clamps.
