Couple of K3 questions

Vic Rosenthal
I have 2 questions about feeding the two receivers in my K3.

1) Say I want to split an antenna and feed both the RX input and the AUX
BNC input. It is recommended to use a 2-way splitter. What would the
effect be if I just used a T connector?

2) I have a 4-way splitter. If I terminate the 2 unused ports it will
have a loss of about 7 dB. If I don't terminate the unused ports,
connect them together (or something) can I reduce the loss?

In other words, I don't have the 2-way splitter I need, what should I do?

Hi Vic,

I tried using a 75 ohm 1x4 Mini-Circuits splitter, but discontinued it
because thanks to some design issue in the K3, it coupled 60 Hz hum from
the power supply for my Titan amp, which sits 6-10 inches below it.  
K6XX uses a BNC Tee, and I adopted that.
