Hello:

Am using a long wire (actually, I guess I should call it a random length
wire) antenna for
receiving only. It runs around the 4 edges of my attic, and then down to
rceiver.

Do listening only up to 30 MHz. Have a JRC NRD 545

Saw an ad for the WinRadio Balun on the Grove site. [The WiNRADiO
WR-LWA-0130 Long Wire Antenna Adapter]

Would sure appreciate any opinions as to whether it's worth getting, and if
it "might" improve receotion
for me ?

Any other thoughts on this would be appreciated.

I've seen, over the years, comments that for receiving only, and using a
long-wire, a Balun to match Z would not
add anything to S/N, and isn't worth even trying.

Others have said in effect, "it can't hurt to match the Z."

A bit confused.
Anyone ever used this unit, or one like it, for receiving ?

Thanks,
Bob

Bob, I doubt that it would help. I have a JRC NRD 525, and I would
imagine the antenna setup on the back of my radio is similar to your
545. There's a connection for a "hi-z" antenna, that is, a long wire,
and the radio has a built-in balun behind that connection to match the
wire to the radio. There is another connnection, a "low-z" connnection
for coax-fed antennas.

If your long wire is connected to your low-z terminal, you're already
in business. About the only additional thing might be to also run a
ground wire from the ground terminal on your low-z terminal to a
little ground rod -- although that probably won't do much to your
reception.

The Win-radio balun would simply duplicate what you already have in
your very fine 545 radio.
