I've been wondering how feeding two receivers from the same antenna
would affect performance.
If the input impedance is as high as I think, there shouldn't be much of
a drop.
I'm trying to compare two receivers on the same signals without the use
of an antenna pre-amp or some sort of active splitter.

* * *Depends on the impedance. Most coaxial inputs are 50 ohms. Single
wires can be much higher....over 300 ohms.

impedance inputs are more complex to isolate.

split without isolation between the two inputs can cause the two
receivers to interact. Tuning one can affect reception in the other.
