I am finishing up the MW receiver..............anyway, I have a high
impedance antenna input in addition to the 50 ohm input. With this type of
receiver is the high impedance input enough, or would interested parties
rather have both inputs.
The reason I am asking this is because my employer would like to have all
jacks mounted to the main PC board. The only thing I have been able to find
so far has been a right angle BNC connector for the 50 ohm input.
Opinions welcomed!

Pete,

I'm in favor of the low-Z input myself. I wouldn't want to connect a
"wire" to any receiver without some robust -- and sacrificial --
isolation.

Would your boss be in favor of using (or recommending one of the
existing) an external impedence matching device with binding posts on
it?
