JTM-30C 100W PEP or 200 W PEP, SINGLE or DUAL
ALL-IN-ONE !
NEW GENERATION NDB WITH ULTIMATE CAPABILITY
EASY AND LOW COST INSTALLATION
COVERS WORLDWIDE NDB SPECIFICATIONS
The JTM-30C transmitter consists of one self con-tained unit (“all-in-one”) including Antenna Tuning & Matching circuits and all Transmitter functions all mounted inside an IP66 weatherproof and rugged-ized cabinet.
As option a Power Supply (AC Mains to 24VDC), diode switching for DC Battery input, and JTM-485/LAN Interface box may be installed inside same Transmitter Cabinet.
The transmitter itself may be powered from any 24V DC source of energy and supply 100W PEP alterna-tively up to 200W PEP from the RF Amplifiers
The equipment may be monitored & controlled from remote located Remote Control, from a local PC, or from any PC worldwide if transmitter supplied with a JTM-485/LAN Interface box.
