I have a remote control system for an R/C boat that
operates on 2.4 GHz (spread spectrum of some sort).
It comes with an antenna that is about 4" long.
Is there a commercial (cheap) one that can extend
the range of the system. I seem to only be getting
about 500' from it now. Thanks.

My guess is you're using a low-end system instead
of a major brand - like Futaba, JR or Spektrum.
Those systems are poorly designed and have just
enough range to work within the capacity of the
cheap model sthat come with them. Not being sarcastic
here, just real. A different antenna wouldn't be
worth the trouble. I suggest that you live with
what you have for now, and if you plan to move on
to more sophisticated models, buy a good system
- the $250 will save you a lot of heartache and
headache.
BTW I've been operating RC models
for many decades and have seen a lot of people make
the mistalke of trying to use those cheap systems
in higher end models with disasterous results.

I'm not familiar with the hobby RC systems at 2.4
GHz, but I agree that your range problems are more
than likely due to poor quality equipment. The stuff
sold as package deals are usually barely qualified.
Price isn't always the ultimate indicator
of quality, but if you do a common sense assessment
of what it takes to produce the equipment and compare
to the price, you can tell pretty well what is junk.
The principle applies to Ham gear as well. Pay
bottom price get bottom performance. I've learned
that the hard way. Nowadays I'll do without before
buying junk. The exception is if the application
is only temporary or for assessment. Then I buy
the mid-to-good-quality equipment.
