[Boatanchors] Re: GB> Collins R-388 vs 51J4

The article that was in Electric Radio a while back
about using television baluns on the older receivers
can be found at

http://k9sth.com/Page_2.html

The link is about 2/3rds the way down the list of
links and is entitled "Using television baluns to
improve receiver sensitivity".

You are correct.   Both are designed to work with a
high impedance whip or single wire antenna.   Some use
a TV receiver balun (nominally 70 to 300 ohms) as a
step-up transformer.  Most are good all the way down
to the upper BC band.
 
Actually many boatanchor receivers are happier with a
Hi-Z antenna up until the late 50's era and benefit
from an "antenna input transformer".
