A couple general antenna questions - is bare wire to be preferred to
plastic coated wire? Thicker wire better than thinner? I own a
Collins 51J-3. I'm using about 20 feet of ordinary speaker wire
(double wire, plastic coated, with the ends twisted together) as an
indoor antenna. I have the wire looped around the top of the wall
unit in which the radio sits. Reception is pretty good - probably a
credit more to the Collins than to my antenna! Can I do better
within the confines of a 8'X10' room? Bear in mind I need wife's
approval too!

Hi Jeff: You may use your wife for a form to hold the 1,000 feet of number
12 awg solid wire, and place it next to the window closest to your Collins.
You'll get great reception with no hassles from YL. Do the dutiful thing of
submitting a missing persons report, but keep a straight face when
interviewed. Good luck.
Actually, you will probably enjoy better results with the speaker wire
split, and therefore not doubled back on itself. Placing the wire behind the
window coverings will help in the domestic relations department, and if
possible, place it just on the perimeter of the glass. Again, good luck.

It makes no difference to the performance of the
antenna if the wire used is coated or bare. However,
if you're using it inside then you really want that
nice plastic covering! Also same with the wire size,
you need really thick wire of 1/2 inch or more to see
any difference and all this does is shorten the
antenna length if you use it for transmitting. For
receiving, more wire length is always better! Split
that speaker wire and either double it's length or use
the second wire as a ground counterpoise, which would
give you a dipole type antenna. Try the dipole setup
first and if you don't see improvement add the wire to
double your now random wire antenna.

Jeff,

Not too sure about the 51J3 but some of the old Collins commercial
receivers had two antenna inputs. One was 50 Ohm with a coaxial
fitting and the other was a nominal 500 Ohm with screw terminals. If
you have the 500 Ohm input you might find using it works better.
