Well, how about some generalized answers to this question, that I've sought
answers to before as well.
Let's assume:
1) 2 wire power cord
2) some problems w/local stations - draping the cord in weird/awkward
positions can help
3) no external connector for antenna
Draping the wire around to improve the reception implies an FM VHF
frequecy - should I assume that?
With AM frequencies a large tuned loop antenna in close proximity to
the internal ferrite antenna can dramatically improve reception.
How about 2 answers?:
1) assume you don't/won't/can't open the case - only external mods
The external things - design and build a pre-tuner to capture the
signal from a real antenna and then capacitively couple it into the
power line with a "gimick" cap like some aluminum foil wraped around a
portion of the cord.
2) assume you could open case
Locate the RF input and bring it to the outside of the case so you can
add an antenna - probably want to disconnect the power cord antenna
too - and take pains to make sure the installation is shock proof,
since the chassis/common may not be isolated from the power line.
Takes some knowledge to pull it off - ideally one wants a balanced
input if it is VHF.
How about same info for battery powered atomic clock? I have one at my
office that works OK near window, but can't get a signal when I put it where
I want it.
There may not be much you can do about that without opening the case
and adding an antenna - typically they receive one or more of the
standard time broadcasts in the HF range - the building is probably
inhibiting the signal. shock isn't an issue with battery power so
that may be a good option - also check out the instructions, they may
already have a solution.
Many thanks,
Steve

I have a clock radio that uses the electrical plug as the antennae.
However, the reception in my bedroom is really bad during the summer
months, but gets somewhat better in the winter months.
Anyway, is there some type of connector plug that I can plug the radio
in to get better reception?
Any help appreciated,
Chris
AM or FM, what frequency? Is there a connection on it for the
antenna? Two or three wire cord?
(some line cord antennas are a piece of steel crimped on the
insulation of the power cord and attach to a screw on the back of the
radio - you remove that and add a wire or dipole antenna to the screw)
Are you able to have an external antenna where you live? Is it only
some distant stations that give you problems?
