The DX-Engineering RTR-1 is perfect for a rig that doesn't have a RX
only input.  Before I got this I also used the T/R feature of the
MFJ-1026 by feeding the RX only antennas via a switch into the noise
antenna  input.  This also provides you with the ability to feed in the
TX antenna for some limited phasing out local noise. My model even has a
built in switchable pre-amp which can help on some RX only antennas as
you may require.
