i'm gonna try that.  i get @#$% for reception here.  of course 2 weeks of rainy 
cold weather and the buildings tween me and downtown may not be helping.

And for those that might still use an antenna
to get reception for a TV, a small blast of WD 40 on the coaxial threads will
give you a better longer lasting connection between you roof top and the TV.

WD-40 works wonders on electrical
contacts.  
 
Once I had an older TV in for
repair and mentioned that when I turned the volume knob (see it WAS old!) it
made a scratchy noise through the speaker.  Repair guy told me to squirt
some WD in there, I did, and no more problem. 
 
Same thing happened with a high
end analog radio tuner I have.  I don't know what exactly I squirted the
WD onto, but it was something making electrical contact inside the unit when I
opened it up and moved when I turned the dial.  Turned it on and problem
was fixed.   
 
Recently had
a  pull switch in the darkroom go "bad" and when I
couldn't find a replacement in the house, I did squirted some WD in there and
now it works fine.  One doesn't need to use a lot.

Nope. WD-40 is just fine on battery contacts. It neither causes
increased resistance of any significance nor - when used sparingly -
is there all that much residue. WD-40 was invented as a water
displacement and rust inhibitor. When used rationally, it is an
excellent cleaner/lube in many contexts. There are probably some ultra
high impedance situations where the film left behind might cause an
undesirable current leak, but these are few and far between. As I
said, I've resurrected all manner of dead/sick electronics - tube,
transistor, FET, and IC - with an appropriate application of this
magic juice to contacts, switches, potentiometers, and the like.

This would also be fine BUT one has to be very careful.  Under no
circumstances would I recommend the use of "Contact Cleaner" type
solutions.  The solvents used in many of these are quite destructive
to plastic.  I've seen components and plastic mounting hardware melt
under the onslaught of contact cleaner.
