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.\u003c\/strong\u003e\n\u003c\/h1\u003e\n\u003ch1\u003e\u003cstrong\u003eTechnical Data Receive Pre-Amplifier MVV 1296 VOX\u003c\/strong\u003e\u003c\/h1\u003e\n\u003ch1\u003e\u003cstrong\u003e Frequency Range 1240-1300 MHz \u003c\/strong\u003e\u003c\/h1\u003e\n\u003ch1\u003e\u003cstrong\u003eNoise figure typ. 0,8-1,2 dB \u003c\/strong\u003e\u003c\/h1\u003e\n\u003ch1\u003e\u003cstrong\u003eAmplification typ. 22 dB \u003c\/strong\u003e\u003c\/h1\u003e\n\u003ch1\u003e\u003cstrong\u003eMax.
