What part of the antenna is broken? Perhaps it can easily be repaired
with a little soldering.If not,look around for any kind of similar shape
and size antenna.Maybe an old rabbit ears tv antenna might work.It's a
thought anyway.Visit some thrift stores in your area and see if there
are any old junk radios there that might have an antenna that might work
ok.Ordering a replacement antenna might cost you a bunch of money.I
think I remember somebody in this news group once griped about the price
of a replacement antenna he was looking at on the internet.Do a search
for,Replacement Antennas for Radios.
