VHT1 Video Transmitter – Replacement for GMS or Cobham ST series

UHF – L-Band – S-Band – C-Band

AMP’s VHT1 Series analog FM video transmitters is an upgraded drop in replacement for the Cobham / GMS ST series video transmitters. It has up to two Line/Mic audio or RS232/TTL data subcarriers and up to 10 Watts output power.

VHT1 transmitters may be configured with fixed RF output powers of 4 Watts or 10 Watts. Transmitters may be optionally configured with remotely selectable power levels utilizing both power levels. AMP’s proprietary power-leveling circuit ensures level output power over the entire frequency band.

Locally configurable features include carrier frequency, high/low output power, video inversion, subcarrier enable, and subcarrier input type. These features and PA on/off, all power modes, and temperature fold-back characteristics may be configured remotely.

With military telemetry heritage, VHT1 transmitters are designed to withstand harsh environments and are ideal for law enforcement, surveillance, Military, and other applications requiring efficient, high quality video/audio/data transmission in a compact, rugged package.
