DX Engineering RTR-2 Modular Receive-Transmit Interfaces provide the easiest and safest method for connecting a dedicated receive antenna to an HF transceiver that does not have a separate receive antenna input. Building upon the innovation of the RTR-1A, our completely redesigned model RTR-2 interfaces now feature three internal slots for these new optional accessory modules:
*DXE-RPA-2-PM Receive Preamplifier Plug-in Module
*DXE-RG5000HD-PM Receiver Guard 5000HD Plug-in Module
*DXE-IT-PM 75 to 50 ohm Impedance Transformer Plug-in Module
DX Engineering RTR-2 Modular Receive-Transmit Interfaces allow the standard transceiver owner to enjoy the advantages of separate receive antennas. These interfaces also add inexpensive failsafe protection for the unswitched receive antenna (RX ANT) port on expensive transceivers.
The RTR-2 is a very useful device for many applications, including:
— Connection of external receiving antennas to transceivers lacking external antenna ports
— T-R antenna switch for older equipment using separate transmitters and receivers
— Interfacing antennas to older phasing or noise cancelling systems
— Addition of a receive preamplifier to any transceiver or transmitter and receiver combination
— Excellent failsafe receiver protection for close-spaced antennas without performance degradation of diode circuits
RTR-2 Modular Receive-Transmit Interfaces are receive-transmit relay units that automatically or manually switch the RF output antenna connector on any HF transceiver between a separate receiving antenna system and a standard transmitting antenna. They are keyed from the transceiver’s ground on transmit amplifier keying line. RTR-2 units feature a unique, failsafe connection method that prevents the hot switching and timing errors that are common on other transmit/receive relays. RTR-2 interfaces switch fast enough for partial break-in CW operation.
There are many simple applications for the new RTR-2 and now internal modules can add dramatically improved reception of those really weak signals on the crowded HF bands!
DX Engineering RTR-2 Modular Receive-Transmit Interfaces enable operators to enjoy improved reception with any low noise receiving antenna system. This shielded enclosure relay system provides a safe method of connecting a receive antenna, such as a Beverage, Active Receive system, or other receiving accessories to your radio.
