I don't know, but I'm using an ARR GasFET preamp at the RXIN/OUT patch
point, and the ARR 0.5 NF seems to be slightly better than the
K3S-series Transverter Interface. Although I own an ARR mast-mount
version, I'm afraid to put it at the tower because the 6M antenna is
only about 10 ft below the SteppIR that I drive legal limit. :) The
loss in my 325 ft of 7/8-in hard line plus coax for rotator loop and
jumper at the shack is is a bit less than 1 dB on 6M.
