[Elecraft] K3 Splitter for Loop RX Antenna ?

[Mike K2MK]

Hi Duane,

I'll jump in with my 2 cents. I use the DXE-RSC-2 splitter from DX
Engineering for my Pixel RX loop. One leg goes to the KXV3A RX IN port for
the Main RX and the other leg goes to the AUX port for the SUB RX. I think
this is what the original poster was trying to accomplish. This would be in
non-diversity use. The DX ENGR unit has a 3db per port loss which I'm sure
is true. But we pretty much expect RX antennas to have somewhat lower gain
than our transmitting antenna. Their advantage is in improved signal to
noise ratio. We make adjustments for this by possibly not using the K3
attenuator or by using the K3 pre-amp. Or we use an external amplifier with
the RX antenna. By taking these steps an additional loss of 3db signal +
noise should not be a show stopper.

73,
Mike K2MK
