Hi all,

I have a 1/4 wave vertical on 440, from this a direct connect to my 440
preamp,
which as a 50 ohm input and output, then a direct connect to a receiver
which
has 2000 ohms impedance.


Something wrong here. It would be very difficult to build anything at 440
MHz that has 2000 Ohm input impedance.

Does it make a different if the receiver input is not exactly matched?
Should
I try to set up the 50ohm to 2000 or step down the 2000 to 50 ohm?
